A Glance at the Role of Sheep in the Transmission and Surveillance of Foot-and-Mouth Disease

Abstract

The study presented serological evidence of exposure to foot-and-mouth disease virus (FMDV) serotype O in sheep from two herds, named Farm A and Farm G, following the
detection of antibodies against non-structural proteins (NSPs), which serve as markers of viral exposure. The herds included unvaccinated animals with no history of foot-andmouth disease (FMD), as reported by their owners. Seropositivity was determined to be 59.09% and 6.25% for Farm A and Farm G, respectively. These findings are discussed with respect to subclinical FMDV infection in sheep and its potential implications for cattle, informed by previous reports.

Koyunların Şap Hastalığının Bulaşması ve Surveyansındaki Rolüne Genel Bir Bakış

Abstract

Bu çalışma, viral maruziyetin belirteçleri olarak işlev gören yapısal olmayan proteinlere (NSP'ler) karşı antikorların saptanmasının ardından, A ve G çiftlikleri olarak adlandırılan iki sürüdeki koyunlarda şap hastalığı virüsü (FMDV) serotip O'ya maruz kalmaya dair serolojik kanıtlar sunmuştur. Sürülerde, sahipleri tarafından bildirildiği üzere, şap hastalığı (FMD) öyküsü olmayan aşılanmamış hayvanlar yer almıştır. Seropozitiflik oranı A çiftliği için %59,09 ve G çiftliği için %6,25 olarak belirlenmiştir. Bu bulgular, koyunlarda subklinik FMDV enfeksiyonu ve bunun sığırlar için potansiyel etkileri açısından, önceki raporlardan yola çıkarak tartışılmıştır.
