Topic:Public Health

The topic of Public Health and horses encompasses the study of interactions between equine populations and human health systems. It involves examining the transmission of zoonotic diseases, which are diseases that can be transferred between animals and humans, as well as the role of horses in the epidemiology of such diseases. This field also considers the impact of equine-related activities on public health, including injuries and environmental effects. Research in this area often explores preventive measures, management strategies, and policies to mitigate health risks associated with horses. This page compiles peer-reviewed research studies and scholarly articles that investigate the intersection of equine and public health, focusing on disease transmission, risk assessment, and health management strategies.
Evolutionary patterns of eastern equine encephalitis virus in North versus South America suggest ecological differences and taxonomic revision.
Journal of virology    November 4, 2009   Volume 84, Issue 2 1014-1025 doi: 10.1128/JVI.01586-09
Arrigo NC, Adams AP, Weaver SC.The eastern equine encephalitis (EEE) complex consists of four distinct genetic lineages: one that circulates in North America (NA EEEV) and the Caribbean and three that circulate in Central and South America (SA EEEV). Differences in their geographic, pathogenic, and epidemiologic profiles prompted evaluation of their genetic diversity and evolutionary histories. The structural polyprotein open reading frames of all available SA EEEV and recent NA EEEV isolates were sequenced and used in evolutionary and phylogenetic analyses. The nucleotide substitution rate per year for SA EEEV (1.2 x 10(-4...
Could work be a source of behavioural disorders? A study in horses.
PloS one    October 28, 2009   Volume 4, Issue 10 e7625 doi: 10.1371/journal.pone.0007625
Hausberger M, Gautier E, Biquand V, Lunel C, Jégo P.Stress at work, as shown by a number of human studies, may lead to a variety of negative and durable effects, such as impaired psychological functioning (anxiety, depression...). Horses share with humans this characteristic of working on a daily basis and are submitted then to work stressors related to physical constraints and/or more "psychological" conflicts, such as potential controversial orders from the riders or the requirement to suppress emotions. On another hand, horses may perform abnormal repetitive behaviour ("stereotypies") in response to adverse life conditions. In the present st...
Stress-related hormones in horses before and after stunning by captive bolt gun.
Meat science    October 28, 2009   Volume 84, Issue 4 634-637 doi: 10.1016/j.meatsci.2009.10.023
Micera E, Albrizio M, Surdo NC, Moramarco AM, Zarrilli A.In this work the slaughter-linked plasma modifications of some stress-related hormones in horses subject to standardized butchering procedures were investigated in order to highlight the compromised animal welfare during pre-slaughter handling. During pre-slaughter, animals show strong hardship behavioural patterns, probably due to being under life-threatening conditions. Blood samples from 12 male horses, ageing from 3 to 5 years, were collected before slaughtering in lairage, and during exsanguination after stunning. Catecholamines, cortisol and beta-endorphin concentrations were assessed in...
Methicillin-resistant coagulase negative staphylococci isolated from horses.
The new microbiologica    October 23, 2009   Volume 32, Issue 3 311-314 
Corrente M, D'Abramo M, Latronico F, Greco MF, Bellacicco AL, Greco G, Martella V, Buonavoglia D.A methicillin-resistant (MR) Staphylococcus epidermidis strain was isolated from a saddle horse affected by osteolysis. MR coagulase-negative staphylococci (MRCNS) were isolated from 11 of 14 (78.8%) horses housed in the same riding club. By typing of the SCCmec region, almost the strains displayed a non typeable (NT) pattern and possessed the ccr type 2. Altogether, the high prevalence of MRCNS and the detection of NT SCCmec types support the hypothesis that horses may represent a reservoir of MRCNS for humans and that equine MRCNS may act as potential source of resistance genes for other sta...
International Equine Ophthalmology Consortium (IEOC) Symposium.
Equine veterinary journal    October 7, 2009   Volume 41, Issue 6 606-607 doi: 10.2746/042516409x447789
Gilger BC, Brooks DE.This first IEOC symposium met its goals of gathering a group of leading equine ophthalmology clinicians and researchers to identify the challenges of the field. To facilitate collaboration, notes from round-table discussions, including the ideas and plans that were discussed are being complied and will be distributed to the attendees. Development of an IEOC membership organisation and website was discussed and supported by the group in an effort further to advance the science of equine ophthalmology. To present results from the collaborations made at this first IEOC meeting, an IEOC mini-sympo...
Trypanosoma evansi infection in mainland Spain.
Veterinary parasitology    October 7, 2009   Volume 167, Issue 1 74-76 doi: 10.1016/j.vetpar.2009.09.050
Tamarit A, Gutierrez C, Arroyo R, Jimenez V, Zagalá G, Bosch I, Sirvent J, Alberola J, Alonso I, Caballero C.An outbreak of Trypanosoma evansi infection that occurred in mainland Spain is described. The outbreak occurred on an equine and camel farm to which dromedary camels from an infected area of the Canary Islands had recently been introduced. One of these camels developed clinical signs and T. evansi was discovered in a blood smear examination. The herd was evaluated in order to determine the extent of the disease. The results showed that 76% of the camels, 35% of the donkeys and 2% of the horses were affected. The animals were isolated and treated using Cymelarsan((R)) (0.5mg/kg). After treatmen...
A zoonotic genotype of Enterocytozoon bieneusi in horses.
The Journal of parasitology    October 6, 2009   Volume 96, Issue 1 157-161 doi: 10.1645/GE-2184.1
Santín M, Vecino JA, Fayer R.This is the first report of Enterocytozoon bieneusi in an equid species. Feces from 195 horses from 4 locations in Colombia were examined for E. bieneusi by polymerase chain reaction. Of these, 21 horses (10.8%) were found positive for E. bieneusi . The prevalence of E. bieneusi in horses 1 yr of age (2.5%). No significant differences in prevalence were observed between male (13.7%) and female horses (9%). Sequencing of the internal transcribed spacer region of the SSUrRNA locus identified 3 genotypes. Two genotypes appear to be unique to horses and were named Horse 1 and Horse 2. A third geno...
Field evaluation of an equine influenza ELISA used in New South Wales during the 2007 Australian outbreak response.
Preventive veterinary medicine    October 1, 2009   Volume 92, Issue 4 382-385 doi: 10.1016/j.prevetmed.2009.08.025
Sergeant ES, Kirkland PD, Cowled BD.During the Australian epidemic of equine influenza in 2007, tens of thousands of horses were infected. From the resulting field data, 475 known infected and 1323 uninfected horses were identified to allow a post outbreak evaluation of the performance of the commonly used bELISA for influenza A under field conditions. A variety of techniques, such as ROC plots, area under the curve and hypothesis testing were used to assess the overall performance of the test. The test was deemed to be accurate (area under curve=0.993+/-0.003 standard error) and significantly informative (z=-32.0; p or =50) wer...
Status of natural infection with Japanese encephalitis virus in Japan: prevalence of antibodies to the nonstructural 1 protein among humans and horses.
Vaccine    September 30, 2009   Volume 27, Issue 50 7129-7130 doi: 10.1016/j.vaccine.2009.09.052
Konishi E.The literature on natural infections with Japanese encephalitis virus in Japan and subclinical:clinical infection rates was summarized. To detect natural infections, conventional serologic methods were used in the past, while nonstructural 1 protein-based methods have been used recently. Annual infection rates in humans and horses indicated the status of natural virus activity in Japan.

Restrictions of anthelmintic usage: perspectives and potential consequences.
Parasites & vectors    September 25, 2009   Volume 2 Suppl 2, Issue Suppl 2 S7 doi: 10.1186/1756-3305-2-S2-S7
Nielsen MK.Given the increasing levels of anthelmintic resistance in equine parasites, parasitologists now recommend traditional treatment approaches to be abandoned and replaced by more sustainable strategies. It is of crucial importance to facilitate veterinary involvement to ensure that treatment decisions are based on parasitic knowledge. Despite recommendations given for the past two decades, strategies based on the selective therapy principle have not yet been implemented on a larger scale in equine establishments. In contrast, treatment regimens appear to be derived from recommendations originally...
Ticks on domestic animals in Pernambuco, Northeastern Brazil. Dantas-Torres F.The objective of this article was to discuss some aspects of ticks associated with domestic animals in the State of Pernambuco, northeastern Brazil, based on a literature review and present new data obtained from recent tick collections carried out in this northeastern Brazilian state. From August 2007 to June 2008, 1,405 ticks were collected and five species were identified: Amblyomma cajennense (Fabricius, 1787), Amblyomma ovale Koch, 1844, Dermacentor nitens Neumann, 1897, Rhipicephalus (Boophilus) microplus (Canestrini, 1887), and Rhipicephalus sanguineus (Latreille, 1806).

The natural history of Anaplasma phagocytophilum.
Veterinary parasitology    September 20, 2009   Volume 167, Issue 2-4 108-122 doi: 10.1016/j.vetpar.2009.09.013
Woldehiwet Z.Anaplasma phagocytophilum is the recently designated name replacing three species of granulocytic bacteria, Ehrlichia phagocytophila, Ehrlichia equi and the agent of human granulocytic ehrlichiosis, after the recent reorganization of the families Rickettsiaceae and Anaplasmataceae in the order Rickettsiales. Tick-borne fever (TBF), which is caused by the prototype of A. phagocytophilum, was first described in 1932 in Scotland. A similar disease caused by a related granulocytic agent was first described in horses in the USA in 1969; this was followed by the description of two distinct granulocy...
Getting to grips with strangles: an effective multi-component recombinant vaccine for the protection of horses from Streptococcus equi infection.
PLoS pathogens    September 18, 2009   Volume 5, Issue 9 e1000584 doi: 10.1371/journal.ppat.1000584
Guss B, Flock M, Frykberg L, Waller AS, Robinson C, Smith KC, Flock JI.Streptococcus equi subspecies equi (S. equi) is a clonal, equine host-adapted pathogen of global importance that causes a suppurative lymphodendopathy of the head and neck, more commonly known as Strangles. The disease is highly prevalent, can be severe and is highly contagious. Antibiotic treatment is usually ineffective. Live attenuated vaccine strains of S. equi have shown adverse reactions and they suffer from a short duration of immunity. Thus, a safe and effective vaccine against S. equi is highly desirable. The bacterium shows only limited genetic diversity and an effective vaccine coul...
Peruvian horse sickness virus and Yunnan orbivirus, isolated from vertebrates and mosquitoes in Peru and Australia.
Virology    September 18, 2009   Volume 394, Issue 2 298-310 doi: 10.1016/j.virol.2009.08.032
Attoui H, Mendez-Lopez MR, Rao S, Hurtado-Alendes A, Lizaraso-Caparo F, Mohd Jaafar F, Samuel AR, Belhouchet M, Pritchard LI, Melville L, Weir RP....During 1997, two new viruses were isolated from outbreaks of disease that occurred in horses, donkeys, cattle and sheep in Peru. Genome characterization showed that the virus isolated from horses (with neurological disorders, 78% fatality) belongs to a new species the Peruvian horse sickness virus (PHSV), within the genus Orbivirus, family Reoviridae. This represents the first isolation of PHSV, which was subsequently also isolated during 1999, from diseased horses in the Northern Territory of Australia (Elsey virus, ELSV). Serological and molecular studies showed that PHSV and ELSV are very s...
Use of quantitative real-time PCR for the detection of Salmonella spp. in fecal samples from horses at a veterinary teaching hospital.
Veterinary journal (London, England : 1997)    September 17, 2009   Volume 186, Issue 2 252-255 doi: 10.1016/j.tvjl.2009.08.022
Pusterla N, Byrne BA, Hodzic E, Mapes S, Jang SS, Magdesian KG.A quantitative real-time (RT)-PCR assay was developed to detect Salmonella spp. in the feces of 911 equine species admitted to a veterinary hospital. Fresh feces and feces enriched for 24h in selenite broth were assessed by conventional culture and by RT-PCR targeting the Salmonella invA gene. The detection limit for the RT-PCR assay was 3 and 10 organisms, respectively, when spiked samples were purified from selenite broth and feces. The analytical specificity was 100% based on the detection of a panel of 40 salmonella serotypes from five serogroups and the lack of cross-reactivity with non-r...
Occurrence of Leishmania sp. in cutaneous lesions of horses in Central Europe.
Veterinary parasitology    September 15, 2009   Volume 166, Issue 3-4 346-351 doi: 10.1016/j.vetpar.2009.09.001
Müller N, Welle M, Lobsiger L, Stoffel MH, Boghenbor KK, Hilbe M, Gottstein B, Frey CF, Geyer C, von Bomhard W.The present report describes a novel etiological agent of cutaneous leishmaniasis in horses that, at least for some cases, sporadically appeared as autochthonous infections in geographically distant regions of Germany and Switzerland. The infection was initially diagnosed upon clinical and immunohistological findings. Subsequent comparative sequence analysis of diagnostic PCR products from the internal transcribed spacer 1 (ITS1) of ssrRNA classified the respective isolates as neither Old World nor New World Leishmania species. However, four isolates subjected to molecular analyses all exhibit...

The equine influenza epidemic in Australia: spatial and temporal descriptive analyses of a large propagating epidemic.
Preventive veterinary medicine    September 12, 2009   Volume 92, Issue 1-2 60-70 doi: 10.1016/j.prevetmed.2009.08.006
Cowled B, Ward MP, Hamilton S, Garner G.Australia experienced a large outbreak of equine influenza in August 2007. Nearly 10000 premises were infected during the epidemic. We used spatial and temporal analytical techniques to describe the epidemic, to quantify important descriptors of the epidemic, and to generate hypotheses about how the epidemic progressed and which control tools assisted in eradication. Spatio-temporal epidemic curves revealed three phases in the epidemic: dispersal, local spread and disease fade out. Spatial dispersal of infection rapidly declined immediately after national movement restrictions were introduced....
Infectious agents detected in the feces of diarrheic foals: a retrospective study of 233 cases (2003-2008).

Viability of Rhodococcus equi and Parascaris equorum eggs exposed to high temperatures.
Current microbiology    September 1, 2009   Volume 60, Issue 1 38-41 doi: 10.1007/s00284-009-9497-5
Hébert L, Cauchard J, Doligez P, Quitard L, Laugier C, Petry S.There is great concern about the potential pathogen contamination of horse manure compost spread in the same fields horses graze in. To ensure that pathogen destruction occurs, temperatures need to be sufficiently high during composting. Here, we investigated the survival rate of two marker organisms, Rhodococcus equi and Parascaris equorum eggs, exposed to temperatures potentially encountered during horse manure composting. Our results show that the time required to achieve a 1 log10 reduction in R. equi population (D-value) are 17.1 h (+/-1.47) at 45 degrees C, 8.6 h (+/-0.28) at 50 degrees ...
Prevalence of vancomycin resistance and multiple drug resistance in enterococci in equids in North India.
Journal of infection in developing countries    August 30, 2009   Volume 3, Issue 7 498-503 doi: 10.3855/jidc.467
Singh BR.Vancomycin resistant and multi-drug-resistant enterococci are the major emerging pathogens in surgical, neonatal, and tertiary care units. Methods: In this study, 267 enterococci from different clinical and non-clinical samples of equine origin were tested for their antimicrobial drug sensitivity against 19 antimicrobials using disc diffusion method. Results: A total of 80.2% enterococci tested were resistant to vancomycin and 99.6% to multiple-drugs. There was a significant association between haemolytic potential and vancomycin resistance (chi(2), 0.00). Enterococci isolates from healthy equ...
