Erciyes Üniversitesi Hayvan Hastanesi'ne 2019-2021 Yılları Arasında Getirilen Neonatal İshalli Buzağılarda Majör Enteropatojenlerin Yaygınlığının Araştırılması.

This retrospective study aimed to determine the incidence rates of BRV, BCoV, E. coli K99+, Cryptosporidiumspp. and Giardia spp. in calves with neonatal diarrhea brought to the Erciyes University, Animal Hospital from farms in Kayseri and its surrounding provinces between 01 August 2019 and 31 August 2021. It was determined that a total of 1839 calves were brought to hospital between the periods above. Of the 1839 calves, 863 were brought to the Ruminant Clinic of Internal Medicine, and 560 of 863 calves (65%) had clinical signs of diarrhea. From the stool samples, BCoV (21.7%) were the most diagnosed single enteropathogen followed by; Cryptosporidium spp. (18.3%), ETEC K99+ (F5) (14.3%), BRV (11.4%) and Giardia spp. (0.6%). As for more than one enteropathogen, Cryptosporidium spp. +BRV (8.0%) were the mostly diagnosed and followed by; BRV+BCoV (7.4%), Cryptosporidium spp. +BCoV (6.3%), BRV+ETEC K99+ (1.1%), BRV+BCoV+Cryptosporidium spp. Diarrhea caused by ETEC K99+ (34.7%) was the most common at 1-7 day-old calves and Cryptosporidium spp. (23.9%) was the most common at 8-14 days calves. In spring and winter seasons, BCoV (22.5%, 25.5%, respectively) was diagnosed mostly and in summer and autumn seasons mostly Cryptosporidium spp. (26.9%, 31.8%, respectively) was diagnosed. As a result, it was revealed that calf diarrhea caused by BCoV was the most common in calves with neonatal diarrhea brought to Erciyes University Animal Hospital from Kayseri and its surrounding provinces between 2019-2021 years. It was concluded that the prevalence of enteropathogens may vary depending on various factors such as sampling place, time, season and the findings obtained from this study may be useful in taking necessary prophylactic and managerial measures for the prevention of calf diarrhea.
