Rev Colomb Cienc Pecu ; According to the World Animal Health Organization-OIE, a carrier stallion has serological positive for antibodies to the virus using the virus neutralisation test or an appropriately validated enzyme-linked immunosorbent assay ELISA and also positive virus isolation from the semen Timoney, Equine viral arteritis uniform methods and rules effective April 19, In America, the presence of EAV has been reported in different countries of South, Central and North America, mainly in Argentina, the United States and Canada where the virus has caused substantial economic losses and is today one of the main pathogens of veterinary importance Figure 3.

Equine Viral Arteritis: epidemiological and intervention perspectives

In contrast, adult males are very likely to become carriers of the virus for long periods of time and can transmit the virus to mares during mating Neu et al. J Am Vet MedAssoc ; Further properties of Equine Arteritis Virus.

In breeders and sites dedicated to reproduction, it is necessary to perform bleeding and serological assays of all horses prior to mating; viral isolation should also be attempted on imported semen before use. The virus can also be spread by the venereal route, including by artificial insemination. Since there is no specific treatment for EVA, once the infection is confirmed clinical management should include rest, fluids and in some cases, broadspectrum antibiotics to reduce the risk of secondary bacterial infections.

The case of Argentine has been largely discussed and documented in the scientific and technical literature, as it is the South American country with the largest number of reported cases. Another symptom of infection in pregnant mares is abortion, that is not preceded by any characteristic or premonitory sign and may occur either at the end of the acute phase of illness or when the recovery phase begins Coignoul and Cheville, ; Vaala et equjna. In paired samples carried out in all of the horses existing in the two farms, no infection was found,andthisdeterminedtheriseofhealthactivities and restrictive measures in the giral of horses movementrestriction DelaSota et al.

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. Of these, 10 were thoroughbreds imported from the U. Cornell Vet ; Genetic divergence with emergence of novel phenotypic variants of equine arteritis virus during persistent infectionof stallions.

The increasing significance of international trade in equids and its influence on the spread of infectious diseases. These measures were subsequently gradually decreased, with today a greater emphasis on controlling the international trade of carrier stallions and infected semen, which have frequently been implicated in the spread of the virus within and between countries Timoney, b.

For females a negative result or stability of neutralizing titers in two serological, evaluated 28 days prior to shipment is required.

J Gen Virol ; This is not to mention the importance of exports which during the same period was over USD Adult horses fully recover from the disease, leaving only the recovered stallions as carriers and sources ofinfection.

J Equine Vet Sci a; A lesser percentage of long-term carrier eqkina can clear the virus spontaneously from the reproductive tracts and do not show risk for transmission of infection Timoney and McCollum, Fatal experimental equine arteritis virus infection of a pregnant mare: EAVnegative mares should mate only with semen from EAV-seronegative stallions, but not with semen from carriers that could be infected.

Virus isolates can be obtained from nasopharyngeal swabs or washes, conjunctival swabs, samples of ejaculates, essentially the sperm-rich fraction, placentas, fetal fluids and tissues of aborted fetuses, such as lung, spleen and lymph nodes, and through blood samples with EDTAas anticoagulant. Twenty-eight days after mating, serological surveys should be performed on the mares to determine if neutralizing antibodies against EAV have developed Holyoak et al.

The Veterinary Clinics of North America. J Ateritis Fertility Suppl ; International Veterinary Information Service www. Serological surveys were conducted in all the horses, two serial diagnostic tests with an interval of 14 days, to verify the absence of viral activity. Genetic characterization of equine arteritis virus during persistent infectionof stallions. Although in Colombia, EVA is an exotic disease, some prevention and control measures have been widely reported, that can make infection a manageable disease, and most importantly, can reduce the direct economic losses produced by disease outbreaks.

The fear that a highly pathogenic strain had emerged, joined with the belief that most horse populations are susceptible to the virus, led to an increased evaluation of the importance of the disease worldwide, imposing severe restrictions on the movement of horses with positive titers of antibodies against the virus Timoney and McCollum, a.
