BACKGROUND: Lentivirus ovivismae and Lentivirus capartenc (formerly maedi-visna and caprine arthritis-encephalitis virus) are highly contagious, chronic viral infections that cause significant economic losses in small ruminant farming. This study aimed to determine the current seroprevalence of these infections in the Yozgat region, where sheep and goat farming is widespread and clinical signs are frequently observed.
MATERIALS AND METHODS: Blood samples were collected from 160 sheep and 160 goats in districts with high small ruminant populations, including Sorgun, Sarıkaya, Saraykent, Boğazlıyan, Şefaatli and Akdağmadeni. The samples were analysed using Lentivirus ovivismae and Lentivirus capartenc enzyme-linked immunosorbent assay (ELISA) tests to detect the presence of antibodies.
RESULTS: Out of the 320 animals sampled, 10 sheep (6.25%) tested positive for Lentivirus ovivismae and 28 goats (17.5%) tested positive for Lentivirus capartenc. These results demonstrate a notable level of viral circulation within the livestock population of the Yozgat Province.
CONCLUSION: The findings indicate that both infections are prevalent in the region, posing a threat to productivity. This study serves as a baseline for informing local veterinarians and farmers about preventive measures. Based on these data, further comprehensive studies and control strategies are planned for the region.
