Abstract

© 2022 Elsevier LtdSchmallenberg orthobunyavirus (SBV), first discovered in 2011, belongs to the Orthobunyavirus genus of the Peribunyaviridae family. SBV, which predominantly infects ruminants, can cause severe fetal malformations when pregnant animals are infected during a critical phase of gestation. In this study, 1590 blood serum samples from cattle, sheep, and goats were obtained for serological investigation and 1604 specimens for virological investigation (including 1414 whole blood with EDTA, 165 vaginal swab samples from aborting animals, and tissue samples from 25 dead and/or aborted fetuses) in private and family-type ruminant establishments in Turkey's Eastern Mediterranean region. All the blood serum samples were tested for the presence of antibodies using ELISA, which showed SBV antibodies in 29.11% (95% CI: 26.89%–31.35%). The virological samples were tested using real-time RT-PCR for SBV nucleic acid presence, which showed 3.17% (95% CI:2.32%–4.04%) were positive. Finally, 10 different Culicoides species (a total of 29,156 Culicoides, including 16,005 females and 13,151 males) were tested to identify the vectors thought to carry infections in the region. However, no SBV nucleic acid was detected in the Culicoides pools.
