J Vet Med Sci ; Equine viral arteritis in perspective in relation to Int trade.
Ann NYA cad Sci b; This article focuses on creating awareness of the key points of infection and on examples of how infection has been distributed in countries that have developed horse breeding, such as Argentina, a country aware of the origin and distribution of the infection.
However, from a practical standpoint, it is difficult to distinguish between EAV strains equlna can cause abortion and those which do not; additionally, there are no standard techniques to classify the strains based on their abortive properties. Equine Respiratory Diseases, P.

Given these figures, an infection could clearly be devastating to our susceptible populations and the risk is too high to be ignored. J Gen Virol ; Further properties of Equine Arteritis Virus.
Genetic characterization of equine arteritis virus during persistent infectionof stallions. Diagnosis Given the clinical similarity of EVA with other equine infectious and non-infectious diseases, any presumptive diagnosis should always be confirmed by laboratory tests Holyoak et al.
Changes in semen quality following experimental equine arteritis virus infection in the stallion. J Eq Vet Sci ; 8: Virulent and avirulent strains of equine arteritis virus induce different quantities ofTNF-alpha and other proinflammatory cytokines in alveolarand blood-derived equine macrophages.
Lactate dehydrogenase-elevating virus, equine arteritis virus, and simian hemorrhagic fever virus: Given the clinical similarity of EVA with other equine infectious and non-infectious diseases, any presumptive diagnosis should always be confirmed by laboratory tests Holyoak et al. These measures were subsequently gradually decreased, with today a greater emphasis on controlling the international trade of arferitis stallions and infected semen, which have frequently been implicated in the spread of the virus arteritid and between countries Timoney, b.
Out of the samples included in this study, Epidemiological status in America. International Veterinary Information Service www. It is necessary to mention that due to EVA is an exotic disease, vaccinations are not recommended in our country yet.
The Veterinary Clinics of North America. For Latin American countries there arenotanofficialreportofprevalence due to there is only few studies and EAV serologic surveyofhorse’spopulationsdoesnotexist. The case of Argentine has equinna largely discussed and documented in the scientific and technical literature, as it is the South American country with the largest number of reported cases.
However, the virus can rapidly be inactivated by low humidity, sunlight, and the use of vlral solvents, or by using common inactivating detergents Burky,Shirai et al. This article focuses on creating awareness of the key points of infection and on examples of how infection has been distributed arteriti countries that have developed horse breeding, such as Argentina, a country aware of the origin and distribution of the infection.

Equine viral arteritis
Genetic stability of equine arteritis virus during horizontal and vertical transmission in an outbreak of equine viral arteritis. Equiba Octoberof three stallions imported to Argentina, one was seropositive, so that the farm was restricted and required sanitation. Vet Pathol ; In total and associated with the first case, there were 30 reported abortions, representing about half the population of pregnant mares exposed to the first infected stallion Timoney et al.
Acknowledgment The author thanks Dr.
From Wikipedia, arrteritis free encyclopedia. EVA is primarily a respiratory disease, transmitted through inhalation of viral particles between horses during the acute stage of infection mainly during transport of the animals for trade, exhibition or racing.
Equine Viral Arteritis: epidemiological and intervention perspectives
However, temporal vlral geographic diversity among EAV isolates has been demonstrated Murphy equinq al. Experimentally, it has become clear that abortion is primarily the result of fetal infection, other than myometritis or damage to the placenta, leading to expulsion of the fetus; in addition, there is evidence that the tissues of the aborted fetus tissues have higher viral titers compared to the mother, stressing the high level of virus replication in the fetus MacLachlan et al.
Virus isolation should be attempted using semen of two separate ejaculations, or mating two EAV-negative mares with the same stallion.
