Bir koyunda akut şiddetli sistiserkozis olgusu. "Hepatitis cysticercosa, Pneumonitis cysticercosa ve Lymphadenitis cysticercosa"#

Cysticercus tenuicollis, köpek, tilki, çakal, kurt gibi karnivorların ince bağırsaklarında yaşayan Taenia hydatigena’nın larva formudur ve dünya üzerinde geniş bir yayılışa sahiptir. Bu form geviş getiren hayvanlar başta olmak üzere birçok küçük memeli hayvanda karaciğer dokusundaki göçü sırasında (Hepatitis cysticercosa) ve akciğerde (Pneumonitis cysticercosa) önemli patolojik bozukluklara sebep olur.

Bu çalışmada Afyon Kocatepe Üniversitesi Veteriner Fakültesi Patoloji Anabilim Dalına getirilen 18 aylık bir koyunun ölüm sebebinin belirlenmesi amacıyla nekropsi yapılmış, organlar ve görülen patolojik lezyonlar paraziter açıdan değerlendirilmiştir. Nekropside karaciğer yüzeyinde birbirlerine paralel veya yer yer birbirlerini kesen yollar şeklinde çok sayıda kanama alanları ile içleri jelatinimsi sıvıyla dolu beyaz pirinç tanesi şeklinde parazit formasyonlarına rastlanmıştır. Bu değişiklikler aynı zamanda organın kesit yüzünde de görülmüştür. İç organlardan alınan kesitler tamponlu nötral formalin solüsyonunda 48 saat süreyle tespit edilmiştir. Doku takibinin ardından parafinde bloklanarak mikrotom aracılığı ile 5-6 mikron kalınlığında kesitler alınmıştır. Kesitlere hematoksilen-eozin (HE) boyası uygulanarak ışık mikroskobunda incelenmiştir. Histopatolojik incelemede karaciğerde, akciğerde ve mezenteriyel lenf yumrularında parazitin kistik formlarına ve bunun yol açtığı lezyonlara rastlanmıştır. Ayrıca kronik peritonitisin bu bulgulara eşlik ettiği dikkati çekmiştir. Sonuç olarak 18 aylık koyunda Hepatitis cysticercosa ve Pneumonitis cysticercosa ve Lenfadenitis cysticercosa yapan sistiserkoz vakası teşhis edilmiştir.

Cysticercus tenuicollis is larval form of Taenia hydatigena that lives in the small intestine of carnivores as dog, foxes, coyote, wolves and has a wide spread on the world. This form causes significant pathological disorder mainly during the migration in the liver (hepatitis cysticercosa) and lung (pneumonitis cysticercosa) especially in ruminants and many small mammals.

In this study, necropsy was made determining of the cause of death of a 18 months sheep and it was evaluated organs and pathological lesions in terms of parasitic aspect which brought to Afyon Kocatepe University Faculty of Veterinary Medicine Department of Pathology. During necropsy, it was found large number of hemorrhages as shape of parallel or crossing each other on the liver surface and it was seen interference forms as shape of white rice which filled with gelatinous liquid. These changes were also seen on the cut surface of organ. The sections taken from internal organs were fixed in neutral buffered formalin for 48 hours. After the following of tissue, it was blocked in paraffin and the sections were obtained via tissue microtome with 5-6 micron. The sections were examined by light microscopy that applied hematoxylin-eosin (HE). It was found cystic forms of the parasite and it caused lesions in liver, lungs and mesenterial lymph nodes in the histopathological examination. In addition, it was noted, peritonitis is accompanied on these findings. As a result, cysticercosis case was diagnosed which caused Hepatitis cysticercosa, Pneumonitis cysticercosa and Lenfadenitis cysticercosa by 18 month sheep.
