Bacteriological and pathological investigation of goat lungs in Mymensingh and determination of antibiotic sensitivity

Abstract

The foremost important goal of the present study was to investigate the bacteriological and pathological conditions in lungs of goats slaughtered in four different slaughter houses/places of Mymensingh Sadar, Mymensingh and in addition to it, antibiotic sensitivity test of commonly used antibiotics in Veterinary practices were performed on isolated bacteria. A total of 75 lungs of slaughtered goats were examined individually and out of which 20 affected lungs were collected for histopathology and bacterial isolation respectively from Mymensingh Sadar, Mymensingh in Bangladesh, during the period from January to May 2013.The lung lesions was grossly recorded 40% in goats (30 out of 75 lungs examined). Grossly, the lung lesions were categorized into (a) hemorrhages 35% (b) congestion 25% (c) hemorrhage and congestion 15% (d) emphysematous lung 15% and (e) hepatization in lung10%. In histopathology, lung lesions were categorized into (a) bronchopneumonia 30%, (b) pneumonia 25% (c) hemorrhagic pneumonia 20% (d) emphysema 15%, (e) purulent pneumonia 10%. Pasteurella sp. (15%) was isolated from the lung lesions of hemorrhagic pneumonia, E. coli. (25%) from bronchopneumonia and Staphylococcus sp. (40%) from purulent pneumonia, focal pneumonia and emphysema, and mixed infection (Staphylococcus sp. and E. coli) 20%. Finally antibiotics sensitivity test was performed on isolated bacteria to which ciprofloxacin was more powerful than others (penicillin, amoxicillin, streptomycin, nalidixic acid and kanamycin) tested and the second one was oxytetracyclin.DOI: http://dx.doi.org/10.3329/bjvm.v11i2.19142Bangl.
