Bacteriological study on pneumonic lungs of slaughtered cattle with special reference to mycobacteria

ABSTRACT

A total of 200 samples of lung tissues and bronchial lymph nodes were collected from 100 cattle slaughtered at Cairo abattoir and examined bacteriologically for isolation of the existing microorganisms which may cause pneumonia with special reference to mycobacteria. The following organisms could be isolated from pneumonic lungs in varying percentages E. coli, Staph. epidermidis, Staph. aureus, micrococci, Strept. pneumoniae, Strept. pyogenes, proteus vulgaris, Enterobacter agglumerans, C. pyogenes and Serratia liquificence. By examination of the collected lung and bronchial lymph node samples showing tuberculous nodules, mycobacteria were isolated from lymph nodes only. Public health significance and economic importance of the isolated microorganisms were discussed
