Erciyes Üniversitesi Hayvan Hastanesi’ne 2019-2021 Yılları Arasında Getirilen Neonatal İshalli Bu-zağılarda Majör Enteropatojenlerin Yaygınlığının Araştırılması

Öz

Bu çalışma, Kayseri ve civar illerindeki çiftliklerden 01 Ağustos 2019 ve 31 Ağustos 2021 tarihleri arasında, Erciyes Üniversitesi, Veteriner Fakültesi, Eğitim Araştırma ve Uygulama Hastanesi’ne getirilen neonatal ishalli buzağılarda BRV, BCoV, E. coli K99+, Cryptosporidium spp. ve Giardia spp.’nin görülme oranlarını belirlemeyi amaçlayan retros-pektif bir araştırmadır. Belirtilen periyotlar arasında, hastaneye toplamda 1839 buzağı getirildiği tespit edildi. Bu buzağı-lardan 863’ünün İç Hastalıkları Anabilim Dalı Ruminant Kliniğine getirildiği ve bunlardan 560’ının (%65) klinik ishal belir-tisine sahip olduğu belirlendi. İshalli buzağılardan alınan dışkı örneklerinden, tek bir enteropatojen olarak en çok, BCoV (%21.7), sonra sırasıyla; Cryptosporidium spp. (%18.3), ETEC K99+ (F5) (%14.3), BRV (%11.4), Giardia spp. (%0.6) tespit edildiği belirlendi. Birden fazla enteropatojen olarak ise en çok, Cryptosporidium spp. + BRV (8.0%), sonra sıra-sıyla; BRV + BCoV (%7.4), Cryptosporidium spp. + BCoV (%6.3), BRV + ETEC K99+ (%1.1), BRV + BCoV + Cryptos-poridium spp. (%2.3) teşhisi konulduğu gözlendi. 1-7 günlük neonatal ishalli buzağılarda en çok ETEC K99+ (%34.7), 8-14 günlük neonatal ishalli buzağılarda ise en çok Cryptosporidium spp. (%23.9) kaynaklı ishal vakalarının görüldüğü belirlendi. İlkbahar ve kış mevsiminde, en çok BCoV (sırasıyla, %22.5, %25.5), yaz ve sonbahar mevsiminde ise en çok Cryptosporidium spp. (sırasıyla, %26.9, %31.8) kaynaklı ishal teşhisi konulduğu görüldü. Sonuç olarak, 2019-2021 yılları arasında, Kayseri ve civar illerinden Erciyes Üniversitesi, Veteriner Fakültesi, Eğitim Araştırma ve Uygulama Hastanesi’ne getirilen neonatal ishalli buzağılarda, en çok BCoV kaynaklı buzağı ishallerinin görüldüğü ortaya konuldu. Enteropatojenlerin prevalansının örnekleme yeri, zamanı, mevsim gibi çeşitli faktörlere bağlı olarak değişebileceği ve bu çalışmadan elde edilen bulguların buzağı ishalinin önlenmesi için gerekli profilaktik ve yönetimsel önlemlerin alınma-sında faydalı olabileceği sonucuna varıldı.

Investigation of the Prevalence of Major Enteropathogens in Neonatal Diarrheic Calves Brought to Erciyes University Animal Hospital between 2019-2021 years

Öz

This retrospective study aimed to determine the incidence rates of BRV, BCoV, E. coli K99+, Cryptosporidi-umspp. 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 Rumi-nant 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 diar-rhea 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.
