Traumatic brain abscess due to Streptococcus equi subspecies zooepidemicus in a Foal. Bacterial infection of the equine central nervous system is rare. This report describes the clinical features, computed tomography (CT) findings, and postmortem results of a 3-month-old female Quarter Horse with an intracranial abscess. Clinical signs included seizures, depression, and bilateral blindness. CT imaging demonstrated a large space-occupying lesion in the left cerebral hemisphere, associated with a frontal bone fracture. Necropsy and histopathology confirmed the presence of an abscess secondary to head trauma. Bacterial culture identified Streptococcus equi subsp. zooepidemicus as...
Assessing Cadmium Levels in Horses Imported from the European Union and Slaughtered in Italy. The aim of this study was to evaluate cadmium (Cd) concentrations in horses imported from various European Union countries and slaughtered in Italy. In addition, we assessed the potential correlation between Cd levels in tissues and organs, and Cd-related gross and histological lesions. The animals were divided into six groups based on age and geographical origin. Among the 430 animals examined, gross renal lesions were observed in only two kidney samples from Polish horses, which also had the highest Cd concentrations: 9.1 mg/kg w/w and 8.23 mg/kg w/w, respectively. Further histological a...
Epizootic situation on horse helminthiases in the northern region of Kazakhstan. The research relevance is predefined by the widespread distribution of parasitosis, including helminthiases, alongside constant depasture on the same areas of pastures, which annually causes massive re‑infection of horses. In this regard, the research aims to identify the age, seasonal, and territorial dynamics of infection of horses with helminthiases in the context of the districts of the northern region of Kazakhstan. The primary research method was an experimental analysis that allowing to consider the dynamics and causes of horse helminthiases, associated with the prepatent period, the ...
Evidence of West Nile virus in chickens and horses in Nigeria: results from a serosurvey. West Nile virus (WNV) is an emerging arbovirus which affects humans and horses. A cross sectional study was carried out on 106 local horses in Kaduna and 78 domestic chickens in Federal Capital Territory. A total of 184 sera were screened for West Nile virus anti Pr‑E antibodies using ID Screen® West Nile competitive enzyme linked immunosorbent assay. For the horses, an overall prevalence of 92.45% was recorded while domestic chickens had a preponderance of 7.69%. From our study, there was a statistical significant difference between the occurrences of WNV in stallions than mares with p <...
Pharmacodynamics and pharmacokinetics of nalbuphine in xylazine‑sedated horses. This study describes the selected pharmacodynamics and pharmacokinetics of nalbuphine (NAL) in xylazine (XYL)‑sedated horses. Five adult healthy horses were randomly received 2 treatments at a 1‑week interval; XYL treatment (0.55 mg/kg IV) and XYL/NAL treatment (XYL, 0.55 mg/kg IV; NAL, 0.3 mg/kg IV). The measured pharmacodynamic variables were sedative and analgesic effects and the effect on ataxia and some physiological parameters. for the pharmacokinetics of NAL, its plasma concentrations were measured using HPLC and a 2‑compartment analysis was performed. Greater and prolonged sedati...
Larvae and adult flies of Rhinoestrus purpureus and R. usbekistanicus: morphology and pupation (Diptera: Oestridae). Rhinoestrus species larvae are considered obligatory parasites of the nasal cavities of equine. This type of myiasis is characterised by sneezing, coughing, olfactory nerve damage and encephalomyelitis. Also, it has a zoonotic importance as the larvae might cause ophthalmomyiasis and conjunctivitis in human. While few studies describing R. purpureus adult fly antennal sensillae are available, the R. usbekistanicus antennal sensillae have never been described. Also, scanty data are available on the adult flies of Rhinoestrus species morphology. For this reason, the current study aimed at identi...
The detection and phylogenetic analysis of equine herpesviruses 1, 4 and 5 identified in nasal swab samples of asymptomatic horses from Serbia and Bosnia and Herzegovina. Nasal swabs originating from 112 apparently clinically healthy and unvaccinated horses of different age, breed and from diverse rearing conditions from Serbia and Bosnia and Herzegovina were examined for the presence of equine herpesviruses 1, 4 and 5 using multiplex nested PCR (Mn‑PCR) and virus isolation. The detected viruses were subsequently characterised by gB gene nucleotide sequencing and their phylogenetic analysis was performed. The infections with EHV‑1, EHV‑4, and EHV‑5 in the examined horse populations are apparently chronic, subclinical and persistent, whilst the shedding ...
The first case of Tyzzer’s disease in a young foal in Italy: a case report. Seizures, coma and death rapidly appeared after admission in a one ‑month‑old foal with a history of lethargy, fever and anorexia. Severe icterus and necrotizing hepatitis were observed at necropsy. Clinical signs, laboratory and postmortem findings were compatible with a suspect of clostridial hepatitis. Tyzzer’s disease was confirmed by the presence of organisms morphologically consistent with Clostridium piliforme in the hepatocytes at the margins of multiple areas of hepatic necrosis. To the authors’ knowledge, this is the first reported case of clostridial hepatitis caused by Clos...
Monolateral chronicon orchitis in a stallion. Orchitis and epididymo-orchitis are inflammatory lesions of the testicle. We herein describe a case of monolateral chronic orchitis which occurred in a Tiro Pesante Rapido (TPR) stallion, born in 2002, with a history of good fertility. The stallion was healthy and asymptomatic although the left testis was found to be smaller as compared with the right one and was hard in consistency. Histopathology examination revealed tubular atrophy and parenchymal sclerosis. Scattered foci of calcification and chronic inflammation, the latter dominated by macrophages and lymphocytes, were also observed. Alt...
Evaluation of serological responses in horses challenged with Burkholderia pseudomallei using current diagnostic tests for glanders. Six horses were challenged experimentally with a strain of Burkholderia pseudomallei isolated from a fatal case of the infection in a dromedary camel years earlier in the Emirate of Dubai. Three horses were inoculated subcutaneously and in 3 the bacterium was administered by the oral route. Four of the horses became serologically positive based on reactions to one or more of the OIE described tests for glanders. B. pseudomallei was re-isolated from the 4 serological positive horses. Only one of the subcutaneously infected horses, developed fever for 3 days. The white blood cell values and the ...
Ex vivo comparison of barbed and unbarbed sutures for the closure of caecal and pelvic flexure enterotomies in horses. In this study the caecum and large colon were harvested from 24 slaughtered horses. On each sample, an 8‑cm long enterotomy was performed. Enterotomies were closed using either barbed or unbarbed glycomer‑631. We compared the time to close, appearance, length of suture material, bursting pressure, and costs associated with each type of material. Our findings demonstrated that time to close was significantly shorter (caecum, P = 0.034; pelvic flexure, P = 0.039) using barbed sutures (caecum 610.4 seconds; pelvic flexure 699.3 seconds) than unbarbed sutures (caecum 661.0 seconds, pelvic flex...
Evaluating African horse sickness virus in horses and field-caught Culicoides biting midges on the East Rand, Gauteng Province, South Africa. A prospective study was undertaken during 2013 and 2014, to determine the prevalence of African horse sickness virus (AHSV) in Culicoides midges and the incidence of infection caused by the virus in 28 resident horses on two equine establishments on the East Rand, Gauteng Province, South Africa. Field caught Culicoides midges together with whole blood samples from participating horses were collected every two weeks at each establishment. Culicoides midges and blood samples were tested for the presence of AHSV RNA by real-time quantitative reverse transcription polymerase chain reaction. Nine i...
Immunological response in horses following West Nile virus vaccination with inactivated or recombinant vaccine. To evaluate the immunological response following vaccination, 40 WNV serologically negative horses were selected and divided in two groups of 20 animals. One group was vaccinated (booster after 28 days) with a whole inactivated viral strain and the second group with a live recombinant canarypox virus expressing the genes coding for the WNV preM/E viral proteins. IgM, IgG and neutralizing antibodies were monitored by class specific ELISAs and serum neutralization assay for 360 days. In both groups, IgM antibodies were first detected 7 days post vaccination (dpv). However, in the group vaccinate...
Cyathostomin faecal egg counts in horse farms from Central Italy. Cyathostomins, or 'small strongyles', are the most important equine helminths because of their worldwide distribution, spread of anthelmintic‑resistant populations, and pathogenic impact. The so‑called 'selective treatment' of those animals exceeding a certain faecal egg count (FEC) has recently been proposed to implement cyathostomin control programmes. The present study evaluated the extent of egg shedding in 475 horses living in 12 farms from 3 regions of Italy. All examined farms and 224 horses (47.6%...
The reliability and forensic soundness of the equine shin circumference measurement in living animals versus post‑mortem examination. Catastrophic injuries in racehorses mostly involve the metacarpal region. Although many studies describe fractures of equine limbs, few examine the relationship between bone morphometrics and musculoskeletal problems in racing horses. And yet, according to the regulation of some Italian traditional races, the shin circumference represents a qualifying prerequisite for horses to be admitted to races. This study aims to evaluate the conformity of the shin circumference measurement in living animals and in post‑mortem examinations, in order to evaluate the forensic reliability of these measurem...
Heart valve pathology in regularly slaughtered horses. In this study we examined macroscopic and microscopic lesions in the mitral valves of 50 regularly slaughtered horses in Italy. Macroscopically the results were minor. Microscopic lesions to the valve were found in both young and elderly subjects, confirming that there is no correlation between age and onset of lesions. We set out to evaluate whether the lesions correspond to valve disorder during the life of the animal.
Exuberant granulation tissue in a horse: successful treatment by the intralesional injection of 4% formaldehyde solution. The healing of wounds located on the equine distal limbs can often be impaired, which can result in exuberant granulation tissue and its associated aesthetic alteration and functional failures. Although a number of therapies have been developed and assessed, the treatment of these wounds still presents challenges. This report describes the treatment of exuberant granulation tissue in a horse using an intra-lesional injection of 4% formaldehyde solution. The successful outcome of this treatment suggests that further investigations are required in order to better evaluate its efficacy, as well a...
Anoplocephala sp. (Cestoda, Cyclophyllidea) infection in horses in Central Italy. Species of Anoplocephalidae are cestodes affecting equines worldwide and causing many intestinal disorders. Between October 2010 and September 2013, 284 faecal samples of horses originating from Lazio Region (Central Italy) were tested for the presence of Anoplocephala sp. eggs by a classic copromicroscopic technique. Data regarding pasture‑dependence/non dependence, age, and sex of the horses were also collected. Statistical analysis, aimed at detecting possible associations between these variables and Anoplocephala sp. prevalence, was performed. Anoplocephala sp. eggs were found in 13% of ...
Total and free iodothyronine changes in response to transport of Equidae (Equus asinus and Equus caballus). In this study the effects of short distance road transport on total and free iodothyronine changes in 12 stallions (Equus asinus and Equus caballus) were evaluated. Donkeys (n = 6) and horses (n = 6) were transported for a distance of 50 km. Blood samples were collected 1 week before transport in basal conditions, 1 week later immediately before loading, and after transport and unloading. After transport, donkeys showed significant increases in circulating T4 (P≤0.01), fT3 (P≤0.001), and fT4 (P≤0.01) levels; while horses had significant increases in circulating T3, fT3 and fT4 (P≤0.01)...
The prevalence of Culicoides spp. in 3 geographic areas of South Africa. The seasonal abundance of Culicoides midges, the vector of Bluetongue and African horse sickness viruses (BTV/AHSV) and the presence of viruses in midges were determined in 3 geographic areas in South Africa. In the Onderstepoort area, more than 500,000 Culicoides midges belonging to 27 species were collected. Eighteen midge species were collected throughout Winter and the presence of AHSV and BTV RNA in midges was detected using real time reverse transcription quantitative polymerase chain reaction. The nucleic acid of AHSV was found in 12 pools out of total pools of 35 Culicoides. Twenty‑f...
The economic impact of Bluetongue and other orbiviruses in sub-Saharan Africa, with special reference to Southern Africa. Bluetongue (BT) and African horse sickness (AHS) are considered the most important orbiviral diseases in Southern Africans countries. The general endemic status makes these diseases challenging to be quanti ed in terms of their economic impact. Using country reported data from BT and AHS outbreaks and cases, as well as international trade data, the economic impact of BT and AHS is evaluated on local, regional, and global scales. Local scale impact in the Southern African region is underestimated as shown by the underreporting of BT and AHS. Exceptions occur during epidemic cycles of the diseas...
Serological surveillance of Leptospirosis in Italy: two‑year national data (2010‑2011). Nowadays, leptospirosis is a re‑emerging widespread infectious disease often underestimate worldwide. The National Reference Centre for Leptospirosis (NRCL), at the Istituto Zooprofilattico Sperimentale della Lombardia e dell'Emilia Romagna, Brescia (Italy), with the cooperation of all the other Istituti Zooprofilattici Sperimentali (IIZZSS), evaluated the distribution of such important zoonosis in Italy. Serological data obtained between 2010‑2011 by each laboratory were collected by the NRCL and discussed. Serum samples collected from 43,935 animal specimens were analysed by the Microsco...
Magnetic resonance imaging features of progressive ethmoid hematoma in 2 horses. Progressive ethmoid hematoma is frequently reported among the pathologies of the upper airways in horses. While several hypotheses have been proposed such as repeated trauma, inflammatory processes and/or chronic infections, congenital phenomena, complication of hemangiomas, and neoplastic processes, the aetiology of this condition is yet unknown. Clinical symptoms are non-specific and includes haemorrhagic nasal discharge, respiratory noise not related to physical exercise and, in most severe cases, phenomena of coughing. The purpose of this case report is to contribute to a correct diagnosti...
First evidence of West Nile virus lineage 2 circulation in Turkey. In August 2014, a West Nile virus (WNV) strain belonging to lineage 2 was detected in the brain tissues of a 9 year old mare euthanised after showing severe clinical signs in Bursa region, Turkey. Phylogenetic analyses of 290 bp of NS3 coding region clustered the Turkish strain together with the 2010-2012 Greek isolates. Either IgG and IgM or IgG only WNV antibodies were detected in 2 and 11 horses, respectively, which were in the outbreak surrounding. No WNV RNA was detected in pools of 50 individuals of Culex pipiens (n = 2), Ochlerotatus caspius (n = 2), and Culex theileri (n = 1) collected...
Hygienic characteristics and microbiological hazard identification in horse and donkey raw milk. Today the interest toward horse (Equus caballus) and donkey (Equus asinus) milk for human consumption is receiving a renewed attention because of its particular composition, hypoallergenicity, and nutraceutical properties. The realistic perspective of global use of this aliment in balanced diets, especially for infancy and geriatrics, poses the need for a more in depth knowledge on milk hygiene and on the health status of dairy animals, as a prerequisite of consumers' safety. The aim of this paper was to review the available literature on the health and hygiene parameters as well as on the pot...

African horse sickness (AHS) is a vector‑borne viral disease of equids, endemic in Sub‑Saharan Africa. This article reports the clinic‑pathological and laboratory findings observed in the framework of passive surveillance during the AHS outbreaks which occurred in Namibia between 2006 and 2013. This study was conducted in the framework of the collaboration among the Istituto Zooprofilattico Sperimentale dell'Abruzzo e del Molise (Teramo, Italy), the Namibian Ministry of Agriculture Water and Forestry, and the Namibian National Veterinary Association. A total of 92 horses were investigate...
Analysis of the 227 bp short interspersed nuclear element (SINE) insertion of the promoter of the myostatin (MSTN) gene in different horse breeds. The myostatin (MSTN) gene encodes a protein known to be a negative regulator of muscle mass in mammalian species. Different polymorphisms of the horse (Equus caballus) MSTN gene have been identified, including single nucleotide polymorphisms and a short interspersed nuclear element (SINE) insertion of 227 bp within the promoter of the gene. The SINE insertion has been associated with performance traits in Thoroughbred racehorses and it was proposed as a predictor of optimum racing distance. The aims of this study were to perform in silico analysis to identify putative gains or abrogation of tr...
New incursions of West Nile virus lineage 2 in Italy in 2013: the value of the entomological surveillance as early warning system. West Nile virus (WNV) is one of the most serious public health threats that Europe and the Mediterranean countries are currently facing. In Italy, WNV emerged in 1998 and has been circulating since 2008. To tackle its continuous incursions, Italian national and regional institutions set up a surveillance program, which includes the serological screening of sentinel horses, sentinel-chickens and backyard poultry flocks and the surveillance on all equine neurological cases, resident captured and wild dead birds, and vectors. This communication aims to assess the importance of the entomological s...
Inactivated and adjuvanted vaccine for the control of the African horse sickness virus serotype 9 infection: evaluation of efficacy in horses and guinea-pig model. African horse sickness (AHS) is a non-contagious viral disease of solipeds transmitted by Culicoides. The disease is endemic in most African countries. Past experience has shown that Italy is a country exposed to emerging infectious diseases endemic to Africa; an incursion of AHS virus together with the widespread presence of Culicoides vectors could be the cause of a serious epidemic emergency. A live attenuated vaccine containing seven of the nine viral serotypes, serotype 5 and 9 are excluded, is commercially available from Onderstepoort Biological Products. However, the use of live vaccine...
Considerations on the sphere of application of European Union animal protection legislation for horses. The increasing awareness of animal welfare issues among consumers and the general public in the European Union has brought about the adoption of laws for the protection of production animals throughout the various steps of the food chain, from breeding to slaughter. Considering that horses may be kept for a variety of reasons, including as companion animals and as farm animals, protective legislation in Europe applies to this species only partially. In consistency with the areas of competence of the European Union, it is the purpose of the activity (be it economic/commercial or neither) and no...
