Abstract

In our
study, we
aimed to present the cases of Coenurus
cerebralis in domesticated
and wild ruminants. The material of
this study consisted of eight sheep, six mountain goats and three cattle
admitted to the Department of Pathology of the Faculty of Veterinary Medicine
of Kafkas University, between 2016 and 2019, for necropsy. The animals
presented various neurological symptoms, including rotation around their axis,
opistotonus, loss of coordination, unilateral blindness and torticollis. Subsequently,
routine systemic necropsy was performed. After routine tissue procedures, 5 μm
thick sections were taken from paraffin blocks prepared for Hematoxylin Eosin
staining. Sections were examined under light microscope to determine the
histopathologic changes. In conclusion,
the cases were diagnosed with Coenurus
cerebralis, in the light of clinical, histopathological and parasitological
findings. In three of the six goats, in addition to these parasitic
cysts, Oestrus ovis larvae were
detected in the frontal sinus. Oestrus
ovis larvae were also observed in three of the eight sheep.

Kars İlindeki Coenurus cerebralis ile enfekte olan Evcil ve Yaban Ruminantların Klinik, Histopatolojik ve Parazitolojik Olarak Değerlendirilmesi

Abstract

Çalışmamızda yerli ve yabani ruminantlarda
gözlenen Coenurus cerebralis
vakalarını sunmayı amaçladık. Bu çalışmanın materyali, 2016 ve 2019 yılları
arasında, nekropsisi yapılmak üzere Kafkas Üniversitesi Veteriner Fakültesi
Patoloji Anabilim Dalı'na kabul edilen sekiz koyun, altı dağ keçisi ve üç sığır
oluşturdu. Hayvanlarda, ekseni etrafında dönme, opistotonus, koordinasyon
kaybı, tek taraflı körlük ve tortikollis gibi çeşitli nörolojik semptomlar gözlendi.
Hayvanların sistemik nekropsisi yapıldı. Rutin doku takip işlemlerinden sonra,
Hematoksilen Eosin boyaması için hazırlanan parafin bloklardan 5 μm kalınlığında
kesitler alındı. Histopatolojik değişiklikleri belirlemek için kesitler ışık
mikroskobu altında incelendi. Sonuç olarak olgulara klinik, histopatolojik ve
parazitolojik bulgular ışığında Coenurus
cerebralis tanısı kondu. Altı keçiden üçünde, bu parazitik kistlere ek
olarak, frontal sinüste Oestrus ovis
larvaları tespit edildi. Sekiz koyunun üçünde de Oestrus ovis larvaları gözlendi.
