The study and analysis of "Domestic Animals" and horses examines the historical domestication, breeding, and management practices that have shaped the role of horses in human society. It also explores the anatomical, physiological, and behavioral characteristics that differentiate horses from other domestic species. Comparative studies often focus on aspects such as nutrition, health management, and the economic and cultural importance of horses relative to other domesticated animals. This page aggregates peer-reviewed research studies and scholarly articles that explore the various dimensions of equine domestication, including genetic studies, welfare considerations, and the impact of domestication on horse behavior and physiology.
Gethmann D.In the early twentieth century, counting and speaking horses, like the famous Clever Hans or the "Horses of Elberfeld," became widely debated subjects in experimental psychology. The idea was to determine whether their learning success was only a fraud, or if it might open up a new chapter in "animal psychology" - or even belong to the realm of parapsychology and telepathy. When their tricks were discovered, the teachers of the animals were marked as charlatans. Both the attempts to detect charlatans and the efforts to avoid this accusation during the talking horse experiments proceeded using ...
Tavenner MK, McDonnell SM, Biddle AS.Early development of the gut microbiome is an essential part of neonate health in animals. It is unclear whether the acquisition of gut microbes is different between domesticated animals and their wild counterparts. In this study, fecal samples from ten domestic conventionally managed (DCM) Standardbred and ten semi-feral managed (SFM) Shetland-type pony foals and dams were compared using 16S rRNA sequencing to identify differences in the development of the foal hindgut microbiome related to time and management. Results: Gut microbiome diversity of dams was lower than foals overall and within ...
Librado P, Orlando L.The equid family contains only one single extant genus, , including seven living species grouped into horses on the one hand and zebras and asses on the other. In contrast, the equine fossil record shows that an extraordinarily richer diversity existed in the past and provides multiple examples of a highly dynamic evolution punctuated by several waves of explosive radiations and extinctions, cross-continental migrations, and local adaptations. In recent years, genomic technologies have provided new analytical solutions that have enhanced our understanding of equine evolution, including the spe...
Souza SS, Alves BG, Alves KA, Brandão FAS, Brito DCC, Gastal MO, Rodrigues APR, Figueireod JR, Teixeira DIA, Gastal EL.Heterotopic and orthotopic ovarian tissue autotransplantation techniques, currently used in humans, will become promising alternative methods for fertility preservation in domestic and wild animals. Thus, this study describes for the first time the efficiency of a heterotopic ovarian tissue autotransplantation technique in a large livestock species (i.e., horses) after ovarian fragments were exposed or not to a cooling process (4°C/24 h) and/or VEGF before grafting. Ovarian fragments were collected in vivo via an ultrasound-guided biopsy pick-up method and surgically autografted in a subcutan...
Kaynarcalidan O, Oğuzoğlu TÇ.Papillomaviruses are oncogenic DNA viruses and induce hyperplastic benign lesions of both cutaneous and mucosal tissues in their various hosts, including many domestic and wild animals as well as humans. There are some Papillomavirus genotypes that can infect hosts different from their own, such as BPV 1 and BPV 2 originated from cattle, which can also infect horses and are responsible for fibroblastic tumours in horses. This review article summarizes the origin and evolution of papillomaviruses as an etiological agent in the historical process. The main focus in this review is the evaluation ...
Li Y, Zhang C, Taylor WTT, Chen L, Flad RK, Boivin N, Liu H, You Y, Wang J, Ren M, Xi T, Han Y, Wen R, Ma J.Horseback riding was a transformative force in the ancient world, prompting radical shifts in human mobility, warfare, trade, and interaction. In China, domestic horses laid the foundation for trade, communication, and state infrastructure along the ancient Silk Road, while also stimulating key military, social, and political changes in Chinese society. Nonetheless, the emergence and adoption of mounted horseback riding in China is still poorly understood, particularly due to a lack of direct archaeological data. Here we present a detailed osteological study of eight horse skeletons dated to c...
Su Y, Zhu J, Salman S, Tang Y.The development of the induced pluripotent stem cells (iPSCs) technology has revolutionized the world on the establishment of pluripotent stem cells (PSCs) across a great variety of animal species. Generation of iPSCs from domesticated animals would provide unrestricted cell resources for the study of embryonic development and cell differentiation of these species, for screening and establishing desired traits for sustainable agricultural production, and as veterinary and preclinical therapeutic tools for animal and human diseases. Induced PSCs from domesticated animals thus harbor enormous sc...
Orlando L.The domestication of the horse some 5,500 years ago followed those of dogs, sheep, goats, cattle, and pigs by ∼2,500-10,000 years. By providing fast transportation and transforming warfare, the horse had an impact on human history with no equivalent in the animal kingdom. Even though the equine sport industry has considerable economic value today, the evolutionary history underlying the emergence of the modern domestic horse remains contentious. In the last decade, novel sequencing technologies have revolutionized our capacity to sequence the complete genome of organisms, including from arch...
Guimaraes S, Arbuckle BS, Peters J, Adcock SE, Buitenhuis H, Chazin H, Manaseryan N, Uerpmann HP, Grange T, Geigl EM.Despite the important roles that horses have played in human history, particularly in the spread of languages and cultures, and correspondingly intensive research on this topic, the origin of domestic horses remains elusive. Several domestication centers have been hypothesized, but most of these have been invalidated through recent paleogenetic studies. Anatolia is a region with an extended history of horse exploitation that has been considered a candidate for the origins of domestic horses but has never been subject to detailed investigation. Our paleogenetic study of pre- and protohistoric h...
Gharekhani J, Yakhchali M, Berahmat R.Knowledge on neosporosis and associated risk factors in different species of animals are so important for designing the control programs and reduce the economic losses globally. This literature review targeted for evaluating the infection rate of in animals in Iran. Until April 2020, all of published documents in the main English and Persian-language databases were searched. A total number of 110 documents (English = 85 and Persian = 25) were extracted. Most of reports were sero-epidemiological studies using ELISA in Iranian cattle population. The range of infection was 3.8-76.2% in ...
Shuaib YA, Isaa MH, Ezz-Eldin MI, Abdalla MA, Bakhiet AO, Chitimia-Dobler L.Morphological abnormalities in ticks have rarely been reported in nature. The existing knowledge about anomalies in ticks collected in Africa is very sparse. In this paper, we describe abnormalities in Amblyomma, Hyalomma, and Rhipicephalus ticks collected from cattle, sheep, goats, camels, and horses in Kassala and North Kordofan states, Sudan, between January and August 2017. A number of 15 adult ticks displayed one or several local anomalies, such as ectromely, abnormalities of the ventral plates, and body deformities, besides newly described multiple cuticula scars. This study presents th...
Todd ET, Thomson PC, Hamilton NA, Ang RA, Lindgren G, Viklund Å, Eriksson S, Mikko S, Strand E, Velie BD.Domestic animal populations are often characterised by high rates of inbreeding and low effective population sizes due to selective breeding practices. These practices can result in otherwise rare recessive deleterious alleles drifting to high frequencies, resulting in reduced fertility rates. This study aimed to identify potential recessive lethal haplotypes in the Thoroughbred horse breed, a closed population that has been selectively bred for racing performance. In this study, we identified a haplotype in the LY49B gene that shows strong evidence of being homozygous lethal, despite having h...
Bressan FF, Bassanezze V, de Figueiredo Pessôa LV, Sacramento CB, Malta TM, Kashima S, Fantinato Neto P, Strefezzi RF, Pieri NCG, Krieger JE....Induced pluripotent stem cells (iPSCs) have enormous potential in developmental biology studies and in cellular therapies. Although extensively studied and characterized in human and murine models, iPSCs from animals other than mice lack reproducible results. Herein, we describe the generation of robust iPSCs from equine and bovine cells through lentiviral transduction of murine or human transcription factors Oct4, Sox2, Klf4, and c-Myc and from human and murine cells using similar protocols, even when different supplementations were used. The iPSCs were analyzed regarding morphology, gene and...
Salat J, Ruzek D.Tick-borne encephalitis (TBE), a disease caused by tick-borne encephalitis virus (TBEV), represents a serious neural infection of humans in Europe and Asia. The main reservoir hosts of TBEV are ticks, rodents and insectivores, but domestic animals may also be infected with the virus. This review summarizes what is known about TBE in domestic species (e.g., dogs, horses), in which infection may manifest with clinical signs similar to those seen in severe human cases. We also focus on TBE in ruminants where TBE infections are typically asymptomatic and do not cause health problems in the infecte...
Hao L, Yuan D, Li S, Jia T, Guo L, Hou W, Lu Z, Mo X, Yin J, Yang A, Zheng W, Li R.Theileria species, with a broad geographic distribution, infect a wide range of both domestic and wild animals and are transmitted by ixodid ticks. Currently, there is no comprehensive report regarding the distribution of Theileria spp. in the eastern Tibetan Plateau, especially in Ganze Tibetan autonomous prefecture (153,700 km) and Ngawa Tibetan and Qiang autonomous prefecture (84,242 km) of Sichuan province, China. In this study, we collected blood samples from yaks (n = 144) (Bos grunniens), Tibetan sheep (n = 92), and Tibet horses (n = 142) in Ganze and Ngawa.Theileria sinen...
Steyn J, Fourie I, Steyl J, Williams J, Stivaktas V, Botha E, van Niekerk S, Reininghaus B, Venter M.Alphaviruses from Africa, such as Middelburg virus (MIDV), and Sindbis virus (SINV), were detected in horses with neurologic disease in South Africa, but their host ranges remain unknown. We investigated the contribution of alphaviruses to neurologic infections and death in wildlife and domestic animals in this country. During 2010-2018, a total of 608 clinical samples from wildlife and nonequine domestic animals that had febrile, neurologic signs or unexplained deaths were tested for alphaviruses. We identified 32 (5.5%) of 608 alphavirus infections (9 SINV and 23 MIDV), mostly in neurotissue...
Mangombi JB, Roqueplo C, Sambou M, Dahmani M, Mediannikov O, Comtet L, Davoust B.Crimean-Congo hemorrhagic fever (CCHF) is a tick-borne disease that can be contracted by direct contact with viremic animals or humans. In West Africa, recurrent CCHF outbreaks have been constantly observed in Mauritania and Senegal. Moreover, acquisition and epidemiology of the infection in humans are correlated with the occurrence and the seroprevalence of the virus in livestock. The main objective of this study is to provide updated information on the local spread of CCHF in animals in the northern region of Senegal. Out of a total of 283 animal sera collected, CCHF-specific antibodies were...
Salek Ardestani S, Aminafshar M, Zandi Baghche Maryam MB, Banabazi MH, Sargolzaei M, Miar Y.Natural selection and domestication have shaped modern horse populations, resulting in a vast range of phenotypically diverse breeds. Horse breeds are classified into three types (pony, light, and draft) generally based on their body type. Understanding the genetic basis of horse type variation and selective pressures related to the evolutionary trend can be particularly important for current selection strategies. Whole-genome sequences were generated for 14 pony and 32 light horses to investigate the genetic signatures of selection of the horse type in pony and light horses. In the overlappin...
Lilly ML, Gonçalves Arruda A, Proudfoot KL, Herron ME.To survey first-year veterinary students' knowledge of companion animal (dog, cat, and horse) behavior and popular-culture (ie, pop-culture) behavior myths related to animal body language, motivations, and learning prior to participation in an introductory animal behavior course; evaluate potential associations between sources of prior behavior knowledge and knowledge on the preclass survey; and determine whether postclass scores on the same survey were predictive of final examination score for the behavior class. Methods: 156 first-year veterinary students. Methods: Students were invited to p...
Pinzon-Arteaga C, Snyder MD, Lazzarotto CR, Moreno NF, Juras R, Raudsepp T, Golding MC, Varner DD, Long CR.Phenotypic selection during animal domestication has resulted in unwanted incorporation of deleterious mutations. In horses, the autosomal recessive condition known as Glycogen Branching Enzyme Deficiency (GBED) is the result of one of these deleterious mutations (102C > A), in the first exon of the GBE1 gene (GBE1). With recent advances in genome editing, this type of genetic mutation can be precisely repaired. In this study, we used the RNA-guided nuclease CRISPR-Cas9 (clustered regularly-interspaced short palindromic repeats/CRISPR-associated protein 9) to correct the GBE1 mutation in a...
Seo MG, Kwon OD, Kwak D.Lyme borreliosis is one of the most prevalent tick-borne infectious zoonotic diseases caused by spirochetes of the sensu lato group. The present study assessed the risk factors and prevalence of Lyme borreliosis in ticks parasitizing domestic and wild animals. A total of 589 ticks (329 tick pools) collected from animals were identified as , (85.7%), (10.0%), and (4.3%) using morphological and molecular methods in South Korea. In this study, the 5S-23S gene sequences of (6/329, 1.8%) were detected in ticks taken from mammals, including ticks from horses (2/147 pools, 1.4%), wild boar (1/19 ...
Šandlová K, Komárková M, Ceacero F.Different forms of direct paternal investment have been described in mammals. One such species where paternal care was noticed, but remains poorly understood, is the horse (Equus caballus), where the male keeps a long-term relationship with several females and offspring. Therefore, the aim of this study was to analyse the interactions between the harem stallion and his foals. Two herds of Exmoor ponies living under semi-feral conditions in two separate reserves within Czech Republic were studied, each during one of the two consecutive breeding seasons (in 2016 and 2017). Both herds consisted o...
Frantz LAF, Bradley DG, Larson G, Orlando L.The domestication of animals led to a major shift in human subsistence patterns, from a hunter-gatherer to a sedentary agricultural lifestyle, which ultimately resulted in the development of complex societies. Over the past 15,000 years, the phenotype and genotype of multiple animal species, such as dogs, pigs, sheep, goats, cattle and horses, have been substantially altered during their adaptation to the human niche. Recent methodological innovations, such as improved ancient DNA extraction methods and next-generation sequencing, have enabled the sequencing of whole ancient genomes. These gen...
Kuzmina ТА, Zvegintsova NS, Yasynetska NI, Kharchenko VA.Resistance of strongylids in domestic horses to benzimidazole anthelmintics (BZ) has been detected worldwide; however, information on the presence of BZ-resistance in wild equids has not been published to date. The purpose of this study was to analyze the manifestations of the BZ resistance in strongylids in domestic and wild equids kept in the Askania Nova Biosphere Reserve, Ukraine. Four species of equids: domestic horses and Shetland ponies (Equus caballus), donkeys (E. asinus), plains zebras (E. burchelli) and Grévy’s zebras (E. grevyi) kept under semi-free conditions were examined usin...
Benfodil K, Büscher P, Abdelli A, Van Reet N, Mohamed-Herif A, Ansel S, Fettata S, Dehou S, Bebronne N, Geerts M, Balharbi F, Ait-Oudhia K.Trypanosoma evansi (T. evansi) is a hemoflagellate parasite that affects a broad range of mammalian hosts and that causes a disease called surra. Diagnosis of surra based on clinical symptoms alone is inaccurate. Therefore, a variety of serological and molecular diagnostic tests are used to assist in the detection of T. evansi infections. The aim of this study was to compare the diagnostic performance of four serological tests (CATT/T.evansi, immune trypanolysis, ELISA with purified variant surface glycoprotein RoTat 1.2 and with whole cell lysate) and two molecular PCR tests targeting sequenc...
Gérard C, Valenchon M, Poulin N, Petit O.In collective movements, some individuals are more effective and attractive leaders than others. Parameters such as social network, personality, and physiologic needs failed to explain why group members follow one leader more than another. In this study in the domestic horse, we propose to focus on the leader's attitude and its impact to the followers' recruitment during two conditions: spontaneous group departures or experimentally induced departures. We postulate that the expressiveness of the leader could enhance its attractiveness and thus produce a successful followership. We found that a...
Höfner L, Luther AM, Waberski D.Ongoing progress in proteomic characterization of seminal plasma has stimulated research on the identification of biomarkers for male fertility and sperm preservability. So far, many studies have evaluated the benefits of reconstituting cryopreserved or sex-sorted semen with seminal plasma. Less information is available about the effect of remaining or added seminal plasma in liquid preserved semen. The interaction between seminal plasma and spermatozoa is species -specific, and within species often complex and ambiguous. This article aims to review the action of seminal plasma on sperm functi...

Morshed MG, Scott JD, Fernando K, Geddes G, McNabb A, Mak S, Durden LA.The blacklegged tick, Ixodes scapularis Say (Acari: Ixodidae), has a wide geographical distribution in Ontario, Canada, with a detected range extending at least as far north as the 50th parallel. Our data of 591 adult I. scapularis submissions collected from domestic animals (canines, felines, and equines) and humans during a 10-yr period (1993-2002) discloses a monthly questing activity in Ontario that peaks in May and October. The Lyme disease spirochete Borrelia burgdorferi Johnson, Schmidt, Hyde, Steigerwalt & Brenner was detected in 12.9% of I. scapularis adults collected from domesti...
Diaz GJ, Boermans HJ.Fumonisins are the most recently discovered group of mycotoxins with important implications in animal health. Equine leucoencephalomalacia and porcine pulmonary edema are diseases observed for many years, but their etiology was unknown. These 2 syndromes were recently reproduced experimentally after administration of purified fumonisin B1 (FB1). The main target organs for the toxic actions of FB1 are the brain in horses and the lungs in the case of swine. However, severe liver damage in both species and pancreatic lesions in swine are also observed, especially when Fusarium moniliforme culture...
Hashimoto-Hill S, Alenghat T.Domestic animals represent important resources for understanding shared mechanisms underlying complex natural diseases that arise due to both genetic and environmental factors. Intestinal inflammation, particularly inflammatory bowel disease (IBD), is a significant health challenge in humans and domestic animals. While the etiology of IBD is multifactorial, imbalance of symbiotic gut microbiota has been hypothesized to play a central role in disease pathophysiology. Advances in genomic sequencing and analytical pipelines have enabled researchers to decipher the composition of the intestinal mi...
Tsachev I, Gospodinova K, Pepovich R, Takova K, Kundurzhiev T, Zahmanova G, Kaneva K, Baymakova M.In recent years, hepatitis E virus (HEV) infection has been found to be widespread among different animal species worldwide. In Bulgaria, high HEV seropositivity was found among pigs (60.3%), wild boars (40.8%), and East Balkan swine (82.5%). The aim of the present study was to establish the seroprevalence of HEV among dogs, cats, horses, cattle, sheep, and goats in Bulgaria. In total, 720 serum samples from six animal species were randomly collected: dogs-90 samples; cats-90; horses-180; cattle-180; sheep-90; and goats-90. The serum samples were collected from seven districts of the country: ...
Davoust B, Maquart M, Roqueplo C, Gravier P, Sambou M, Mediannikov O, Leparc-Goffart I.In Africa, infection with West Nile virus (WNV) is frequent but almost always asymptomatic in humans and equids. The aim of this study was to identify whether any other domestic animal living in the same enzootic locality may be the sentinel of WNV circulation. In northwest Senegal, blood samples were collected from 283 adult domestic animals (136 sheep, 64 horses, 29 donkeys, 29 goats, 14 cattle, and 11 dogs), in three localities near Keur Momar Sarr. Each serum was tested for WNV immunoglobulin G using enzyme-linked immunosorbent assay. The prevalence among donkeys, horses, dogs, goats, catt...
Higuchi RG, Wrischnik LA, Oakes E, George M, Tong B, Wilson AC.Sequences are reported for portions of two mitochondrial genes from a domestic horse and a plains zebra and compared to those published for a quagga and a mountain zebra. The extinct quagga and plains zebra sequences are identical at all silent sites, whereas the horse sequence differs from both of them by 11 silent substitutions. Postmortem changes in quagga DNA may account for the two coding substitutions between the quagga and plains zebra sequences. The hypothesis that the closest relative of the quagga is the domestic horse receives no support from these data. From the extent of sequence ...
Taylor WTT, Barrón-Ortiz CI.Despite its transformative impact on human history, the early domestication of the horse (Equus caballus) remains exceedingly difficult to trace in the archaeological record. In recent years, a scientific consensus emerged linking the Botai culture of northern Kazakhstan with the first domestication of horses, based on compelling but largely indirect archaeological evidence. A cornerstone of the archaeological case for domestication at Botai is damage to the dentition commonly linked with the use of bridle mouthpieces, or "bit wear." Recent archaeogenetic analyses reveal, however, that horse r...
Jones SL, Maggi R, Shuler J, Alward A, Breitschwerdt EB.Bartonella spp. are emerging zoonotic agents that have been found in a wide variety of domestic animals and wildlife and cause a number of clinical syndromes. Bartonella sp. infection has been identified in a growing number of animal species, including cats, rodents, porpoises, and canids, but has not been reported in horses. Objective: To document the presence of Bartonella sp. in the blood of horses. Methods: One horse with chronic arthropathy and 1 horse with presumptive vasculitis. Methods: Blood samples were tested for the presence of Bartonella sp. by a combination of multiplex real-time...
Gershwin LJ.Allergic responses occur in humans, rodents, non-human primates, avian species, and all of the domestic animals. These responses are mediated by immunoglobulin E (IgE) antibodies that bind to mast cells and cause release/synthesis of potent mediators. Clinical syndromes include naturally occurring asthma in humans and cats; atopic dermatitis in humans, dogs, horses, and several other species; food allergies; and anaphylactic shock. Experimental induction of asthma in mice, rats, monkeys, sheep, and cats has helped to reveal mechanisms of pathogenesis of asthma in humans. All of these species s...
Ludwig A, Reissmann M, Benecke N, Bellone R, Sandoval-Castellanos E, Cieslak M, Fortes GG, Morales-Muñiz A, Hofreiter M, Pruvost M.Leopard complex spotting is inherited by the incompletely dominant locus, LP, which also causes congenital stationary night blindness in homozygous horses. We investigated an associated single nucleotide polymorphism in the TRPM1 gene in 96 archaeological bones from 31 localities from Late Pleistocene (approx. 17 000 YBP) to medieval times. The first genetic evidence of LP spotting in Europe dates back to the Pleistocene. We tested for temporal changes in the LP associated allele frequency and estimated coefficients of selection by means of approximate Bayesian computation analyses. Our result...
Haghi MM, Etemadifar F, Fakhar M, Teshnizi SH, Soosaraei M, Shokri A, Hajihasani A, Mashhadi H.Babesiosis is a protozoal disease caused by Babesia spp. in mammals and humans worldwide. It is one of the most important tick-borne diseases, which affects livestock productions, reproductions, and accordingly failing economy. In this, systematic review and meta-analysis, study, the prevalence of babesiosis among domestic herbivores in Iran, between 1998 and 2015, was methodically reviewed. Nine databases including five English and four Persian databases were explored. A total of 49 articles, as regards the examination of 13,547 sheep, 1920 goats, 7167 cattle, and 940 horses, corresponding to...
Wutke S, Benecke N, Sandoval-Castellanos E, Döhle HJ, Friederich S, Gonzalez J, Hallsson JH, Hofreiter M, Lõugas L, Magnell O, Morales-Muniz A....Horses have been valued for their diversity of coat colour since prehistoric times; this is especially the case since their domestication in the Caspian steppe in ~3,500 BC. Although we can assume that human preferences were not constant, we have only anecdotal information about how domestic horses were influenced by humans. Our results from genotype analyses show a significant increase in spotted coats in early domestic horses (Copper Age to Iron Age). In contrast, medieval horses carried significantly fewer alleles for these phenotypes, whereas solid phenotypes (i.e., chestnut) became domina...
Bundgaard L, Jacobsen S, Sørensen MA, Sun Z, Deutsch EW, Moritz RL, Bendixen E.Progress in MS-based methods for veterinary research and diagnostics is lagging behind compared to the human research, and proteome data of domestic animals is still not well represented in open source data repositories. This is particularly true for the equine species. Here we present a first Equine PeptideAtlas encompassing high-resolution tandem MS analyses of 51 samples representing a selection of equine tissues and body fluids from healthy and diseased animals. The raw data were processed through the Trans-Proteomic Pipeline to yield high quality identification of proteins and peptides. T...
Khalili M, Sakhaee E, Bagheri Amiri F, Safat AA, Afshar D, Esmaeili S.Leptospirosis is a neglected infectious zoonotic disease that affects domestic animals and wildlife as well as humans. Although leptospirosis is known as an endemic disease in Iran, there is no accurate information on the overall prevalence of this disease in humans and animals. The aim of this systematic review and meta-analysis was to estimate the seroprevalence of leptospirosis among human and domestic and wild animals in Iran. A systematic review of English and Persian articles (since 1998 to December 2017) was conducted using Google Scholar, Medline/PubMed, Science Direct, Scopus, Web of ...
Spolidorio MG, Labruna MB, Machado RZ, Moraes-Filho J, Zago AM, Donatele DM, Pinheiro SR, Silveira I, Caliari KM, Yoshinari NH.Blood samples collected from 201 humans, 92 dogs, and 27 horses in the state of Espirito Santo, Brazil, were tested by polymerase chain reaction, indirect immunofluorescence assays, and indirect enzyme-linked immunosorbent assay for tick-borne diseases (rickettsiosis, ehrlichiosis, anaplasmosis, borreliosis, babesiosis). Our results indicated that the surveyed counties are endemic for spotted fever group rickettsiosis because sera from 70 (34.8%) humans, 7 (7.6%) dogs, and 7 (25.9%) horses were reactive to at least one of the six Rickettsia species tested. Although there was evidence of ehrlic...
Sun Y, Liu Z, Ren L, Wei Z, Wang P, Li N, Zhao Y.This review focuses on the diversity of immunoglobulin (Ig) genes and Ig isotypes that are expressed in domestic animals. Four livestock species-cattle, sheep, pigs, and horses-express a full range of Ig heavy chains (IgHs), including μ, δ, γ, ϵ, and α. Two poultry species (chickens and ducks) express three IgH isotypes, μ, υ, and α, but not δ. The κ and λ light chains are both utilized in the four livestock species, but only the λ chain is expressed in poultry. V(D)J recombination, somatic hypermutation (SHM), and gene conversion (GC) are three distinct mechanisms by which immunog...
Sofizadeh A, Telmadarraiy Z, Rahnama A, Gorganli-Davaji A, Hosseini-Chegeni A.A survey on tick species composition was carried out in Golestan Province Iran during year 2010-2011.The aim was to determine tick species parasitizing domestic ruminants and their seasonal population dynamics. Methods: A total of 124 sheep, 92 goats, 84 cattle, 74 camels and 12 horses in several villages were inspected for tick infestation. The collected ticks preserved in 70% alcohol and then were identified. Results: The overall 1059 ticks (453 female, 606 male) were collected. The ticks occur on sheep, goats, cattle, camels and horses as 72.1%, 77.3%, 75.8%, 69.3%, and 50% respectively. Th...
Benfodil K, Büscher P, Abdelli A, Van Reet N, Mohamed-Herif A, Ansel S, Fettata S, Dehou S, Bebronne N, Geerts M, Balharbi F, Ait-Oudhia K.Trypanosoma evansi (T. evansi) is a hemoflagellate parasite that affects a broad range of mammalian hosts and that causes a disease called surra. Diagnosis of surra based on clinical symptoms alone is inaccurate. Therefore, a variety of serological and molecular diagnostic tests are used to assist in the detection of T. evansi infections. The aim of this study was to compare the diagnostic performance of four serological tests (CATT/T.evansi, immune trypanolysis, ELISA with purified variant surface glycoprotein RoTat 1.2 and with whole cell lysate) and two molecular PCR tests targeting sequenc...
Haase B, Signer-Hasler H, Binns MM, Obexer-Ruff G, Hauswirth R, Bellone RR, Burger D, Rieder S, Wade CM, Leeb T.Coat color and pattern variations in domestic animals are frequently inherited as simple monogenic traits, but a number are known to have a complex genetic basis. While the analysis of complex trait data remains a challenge in all species, we can use the reduced haplotypic diversity in domestic animal populations to gain insight into the genomic interactions underlying complex phenotypes. White face and leg markings are examples of complex traits in horses where little is known of the underlying genetics. In this study, Franches-Montagnes (FM) horses were scored for the occurrence of white fac...
Azócar-Aedo L.Leptospirosis is an important zoonosis worldwide. This disease affects numerous animal species, some of them are classified as "maintenance hosts", and others are categorized as "incidental hosts". Humans are at risk of becoming infected by having contact with domestic and wild animals. In this paper, general aspects of the etiology and transmission of leptospirosis are addressed, data regarding the clinical presentation of the pathology in humans and animals are also presented, and the results of some epidemiological studies on leptospirosis carried out in Chile in different animal species an...
Oliveira-Neto MP, Pirmez C, Rangel E, Schubach A, Grimaldi Júnior G.From July 1984 to September 1986, 105 cases of American cutaneous leishmaniasis were studied in a locality closely situated to an urbanized area of the city of Rio de Janeiro, Brazil. Settlement in this area was established at least 20 years ago but the first cases were noted six months prior to the beginning of this study. Cases were almost exclusively cutaneous and ulcerated, with one to six months of evolution. Montenegro's skin tests were positive in all cases and anti-Leishmania antibodies were detected by indirect immunofluorescence test in 74.3% of the patients. Parasites were demonstra...
Park W, Kim J, Kim HJ, Choi J, Park JW, Cho HW, Kim BW, Park MH, Shin TS, Cho SK, Park JK, Kim H, Hwang JY, Lee CK, Lee HK, Cho S, Cho BW.Previous studies of horse RNA-seq were performed by mapping sequence reads to the reference genome during transcriptome analysis. However in this study, we focused on two main ideas. First, differentially expressed genes (DEGs) were identified by de novo-based analysis (DBA) in RNA-seq data from six Thoroughbreds before and after exercise, here-after referred to as "de novo unique differentially expressed genes" (DUDEG). Second, by integrating both conventional DEGs and genes identified as being selected for during domestication of Thoroughbred and Jeju pony from whole genome re-sequencing (WG...
Davis E.Donkeys and mules have been critical to the development of human civilization, since being domesticated some 6000 years ago. However, they suffer from being undervalued or ignored by development agencies and animal protection nongovernmental organizations. Where they are recognized as affecting agriculture and the economy it is often because they are seen as being either invasive pests or an anachronism in the developing countries of the twenty-first century. Even in the wealthier societies of the world, donkeys suffer from ignorance about their proper management or a booming industry in heal...
Hanot P, Herrel A, Guintard C, Cornette R.The relationships between the different component parts of organisms, such as the sharing of common development or function, produce a coordinated variation between the different traits. This morphological integration contributes to drive or constrain morphological variation and thus impacts phenotypic diversification. Artificial selection is known to contribute significantly to phenotypic diversification of domestic species. However, little attention has been paid to its potential impact on integration patterns. This study explores the patterns of integration in the limb bones of different ho...
Pot B, Devriese LA, Hommez J, Miry C, Vandemeulebroecke K, Kersters K, Haesebrouck F.Strains of Vagococcus fluvialis, a species of Gram-positive catalase-negative cocci, related to the genera Enterococcus and Carnobacterium, were isolated from various lesions of pigs, from lesions and tonsils of cattle and cats and from tonsils of a horse. Most lesion strains were isolated in mixed culture from animals with disease conditions unrelated to coccal infection. Certain differences with the species description of Vagococcus fluvialis were found: only a proportion of the strains was motile; many strains gave positive reactions to Voges-Proskauer, alkaline phosphatase and leucine aryl...
Aho R.Hair samples from domestic and laboratory animals with suspected dermatophytosis were examined for the presence of saprophytic fungi. A nutritionally poor base medium, developed by the author, was used in the isolation and identification of the saprophytes. Three hundred and ninety-four specimens were examined of which 246 were from dogs, 75 from cats, 30 from horses, 19 from cows, 12 from guinea pigs, 5 from rats, 2 from parakeets, 2 from chinchillas and one each from a goat, a mink and a lesser panda (Ailurus fulgens). Moulds classified in 32 genera were isolated. The commonest in order of f...
