Abstract
Mass spontaneous abortions among pregnant mares, neonatal death of newborn foals and signs of infection of mares and stallions with an infectious disease of unknown etiology are recorded annually in the territory of the Kyrgyz Republic (KR). Since 2008, such mass cases have been recorded in the Issyk-Kul and Naryn regions. Our goal was to identify potential viral pathogens that lead to all of these above economic losses for farmers in the Kyrgyz Republic. In our studies, potential viral causes of late abortions, stillbirths, and neonatal deaths in foals were investigated in horse population of KR by serological tests. Using the ELISA method, we determined the susceptibility of the KR horse population to equine herpes viruses type 1 (EHV1) and type 4 (EHV-4). In total, 18 blood serum samples were taken from horses from the Jeti-Oguz district of the Issyk-Kul region, in the farms where cases of late mass abortions, neonatal death of foals and death of horses from a disease with unknown etiology were previously detected. Serological studies showed that antibodies against EHV-1 and EHV-4 were detected in the population of the studied horses. On the territory of the Kyrgyz Republic, earlier mass scheduled vaccinations of horses were not carried out, antibodies were produced precisely in response to the penetration of infectious foreign agents, in our case against to EHV-1 and EHV-4. EHV-4 affects the respiratory system and is not related to abortion. Based on this, we suggest that EHV-1 is one of the potential causative agents of diseases in horses that lead to mass abortions of mares and neonatal death of foals
