GANGRENOUS MASTITIS IN COWS: PATHOLOGICAL, MICROBIOLOGICAL AND SURGICOTHERAPEUTICAL INVESTIGATION (Pages : 29 - 36)

Gangrenous mastitis in cows was investigated at Dinajpur district of Bangladesh. The animals brought to clinics for the diagnosis and treatments were examined clinically, pathomicrobiologically and surgicotherapeutically. Out of 29 mastitis cases, only 7 cases of gangrenous mastitis were recorded. The signs, lesions and the causative organisms were characterized clinically, pathologically and bacteriologically, respectively and the surgicotherapeutical responses of the patients were noted. A presumptive diagnosis was done based on the identification of the organisms by preparing impression smears stained with Gram’s stain. The organisms were finally isolated and identified by culturing and biochemical properties of the organisms in differential sugar media without typification. The animal was accepted for the amputation of the gangrenous portion (s) despite of the doubtful negative prognosis. The amputed tissues, exudates and the milk samples were collected taking necessary precautions for bacteriological as well as gross and histopathological examinations. The formalin fixed tissues were processed, sectioned and stained with haematoxylin and eosin for the histopathological examination. Possible all measures were taken carefully during the course of surgical operation giving emphasis on to less painful operation, check more bleeding, compensate fluid and electrolytes loss, provide hygienic measurement to avoid contamination and complications, and also taken necessary postoperative care.Both local and systemic signs of the disease were recorded and characterized clinically as anorexia, moderate elevation of the body temperature, dehydration, depression, reluctant to walk. The lesions were morphopathologically characterized as extremely swollen, bluish discoloration, foul smelling, serosanguineous odoriferous exudation, painless and cool to touch that indicated the development of moist gangrenous mastitis. The causative organisms (Staphylococci, Bacilli, and E. coli) Download
