Pathologic investigations on tuberculosis and other granulomatous pneumonia in cattle

Abstract

The study was carried out to reveal the pathology and Incidence of tuberculosis (Tb) that currently increased and other granulomatous pneumonia (GP) in cattle. For this purpose, the lungs and the mediastinal-bronchial lymph nodes of 4062 cattle slaughtered at Konya Konet Slaughterhouse were examined, and in 53 (1.30 %) cases, GP were determined. Out of these cases, 45 (85 %) tuberculosis, 6 (11.3 %) actinobacillosis and 2 (3.7 %) pneumomycosis were diagnosed. In addition to these cases, tuberculous granulomas were found in 4 mediastinal lymph nodes as well, making up a totally 49 (1.2 %) Tb cases. Certain and differential diagnosis of these diseases was performed by typical macroscopic and microscopic features of the lesions and observations of agents on sections stained with specific staining methods. It has concluded that, by taking account To which made up 85 % of GP, GPs In cattle need to be examined in terms of Tb. Besides, that 1.2 % of all examined cattle suffers from Tb has shown the importance of antemortem and postmortem examinations in abattoirs lor public health.
