Bu çalışmada, Erciyes Üniversitesi Veteriner Fakültesi Patoloji Anabilim Dalı’na nekropsi amacıyla getirilen 2 yaşlı dişi kaya-cami güvercini ve 4 aylık 2 adet evcil taklacı güvercinde tüberküloz olgusu tanımlandı. Makroskobik incelemede, kaya güvercininde kaşektik tablo ile birlikte akciğer kesitlerinde toplu iğne başı büyüklüğünde sarımtırak renkte birkaç nodül görüldü. Taklacı güvercinlerin bir tanesinin sağ kanat altında gri-sarımtırak renkte 1 x 1.5 x 0.8 cm ebatlarında, karaciğer yüzeyinde ve barsakta jejunum üzerinde 0.5-1 mm’den 1 cm’ye kadar değişen büyüklükte, kursağa yakın 0.3 x 0.8 cm’lik gri-sarımtırak renkte nodüllerin varlığı dikkati çekti. Diğer taklacı güvercinde ise akciğerde 1 x 1.2 x 0.5 cm ve karaciğerde 0.5 x 0.7 x 0.6 cm ebatlarında gri-sarımtırak renkte nodüler yapılar görüldü. Histopatolojik incelemede bu nodüller lezyonların homojen eozinofilik renkte kazeifikasyon nekrozu olduğu, bunların çevresinde çok çekirdekli dev hücreleri, epiteloid histiyositler, histiyosit, lenfosit ve en dışta da fibröz bir kapsülden oluşan tipik tüberküllerden oluşan tüberküloz lezyonları olduğu gözlendi. Yapılan Ziehl-Neelsen boyamasında kaya güvercininde tüberküloz basilleri gözlenmezken, taklacı güvercinlerin her ikisinde de tüberkül yapılarında çok sayıda yoğun kırmızı renkte küçük kümeler halinde tüberküloz basilleri tespit edildi. Etkenin zoonoz karakterde olması ve kontaminasyon riski nedeniyle olgu sunumu şeklinde değerlendirilmiştir.

Spontaneous Tuberculosis Cases In Two Pigeon Flocks

Öz

In this study, a 2-year-old female rock pigeon and two 4-month-old tumbler domestic pigeon brought to Erciyes University, Faculty of Veterinary Medicine, Department of Pathology, for necropsy were diagnosed as tuberculosis. On the macroscopic examination, several nodules with yellowish colour were seen in the pulmonary sections as well as in the rock pigeon. The grey-yellowish nodules were found on the right wings (1 x 1.5 x 0.8 cm in size), the liver surface and the jejunum in the small intestine (with a size ranging from 0.5-1 mm to 1 cm) and near the craw (0.3 x 0.8 cm in size) of the one tumbler pigeon. In other, grey-yellowish nodular structures were seen in the lungs 1 x 1.2 x 0.5 cm and 0.5 x 0.7 x 0.6 cm in the liver. Histopathological examination showed that these lesions were tuberculous lesions consisting of homogeneous eosinophilic colourized casein necrosis, surrounding multi-nucleated giant cells, epithelioid histiocytes, histiocytes, lymphocytes and, most extensively, typical tubercles with a fibrous capsule. According to In the Ziehl-Neelsen staining, tuberculous bacillus was not observed in the tissue of rock pigeon, while tuberculous bacillus was found in a large number of dense red in tubercle structures in both of the tumbler pigeons. Because of the zoonotic nature of the agent and the risk of contamination, it was evaluated as a case report.
