Potentially Pathogenic Bacteria from Pneumonic Bovine Lungs

Abstract

This work was carried out to isolate and study the bacterial agents associated with pneumonia in cattle. Bacteriological examination of 50 samples, collected at random, from Ganawah, Elkadaro and Elbugaa Slaughter houses during September, 2002 to December 2002 was carried out. Thirty samples were positive for bacterial growth (60%), yielding 49 species in 9 genera. Staphylococcus aureus (6.12%), S. epidermidis (4.08%), S. heamolyticus (4.08), S. hysicus (4.08%), S. saprophyticus (4.08%), S. xylosus (4.08%), S. auricularis (2.04%), S. lentus (2.04%), S. sciuri (2.04%), Streptococcus bovis (8.16%), St. pyogenes (8.16%), St. equi (4.08%), St. pneumoniae (4.08%), St. uberis (2.04%), St. zooepidemicus (2.04%), Klebsiella pneumoniae (14.28%), Corynebacterium pseudotuberculosis (8.16%), Arcanobacterium pyogenes (2.04%), Arachnia propionica (2,04), Micrococcus agilis (2,04), Pseudomonas aeruginosa (2.04%) and Proteus vulgaris (2.04%). Sensitivity tests were performed using eight different antibiotics, including: Gentamicin, Penicillin, Ampicillin, Streptomycin, Erythromycin, Chloramphenicol, Tetracycline and Cloxacillin. All isolates were found to be sensitive to Chloramphenicol and Gentamicin in varying degrees. Sensitivity to other antibiotics varied from one species to another.
