Serotypes of Salmonella isolated from feces of cattle, buffalo, and camel and sensitivities to antibiotics in Turkey

Abstract

In this study,Salmonellastrains from dairy cows, calves with diarrhea, and buffalo and camel feces were isolated andserotyped. There were 869 feces samples (437 calves, 287 dairy cows, 100 buffalo, and 45 camels) collected from 13 provinces and 21farms. Preenrichment feces samples were added to Rappaport-Vassiliadis medium. Samples were then subcultured on xylose lysinetergitol-4 agar and plates. Suspected colonies ofSalmonellawere confirmed by latex agglutination test. The isolates ofSalmonellaspp.were serotyped at the Etlik Central Veterinary Control Institute. In total, 40Salmonellaspp .were isolated, including 33 from calves, 5from dairy cows, 1 from a buffalo, and 1 from a camel.Salmonellastrains were serotyped asS.Kentucky (n = 23),S . Muenchen (n =5),S . Anatum (n = 4),S.Gaminare (n = 4),S . Typhimurium (n = 1),S.Muenster (n = 1),S.Enteritidis (n = 1), andS.Abony (n = 1). The Kirby-Bauer disk diffusion method was used for the determination of antibiotic susceptibilities of isolates against 15 antibiotics.Salmonellaisolates were determined as resistant to multiple antibiotics. In conclusion, 8 differentSalmonellaserotypes were found indairy cows, calves, buffalo, and camels. Because of the occurrence of multiresistant isolates, biosafety measures and pathogen controlprocesses are advised forSalmonella -associated risks to public health.
