YA Sabiel, MT Musa, HE Ahmed


Little work have been done in the Sudan concerning the association of different bacteria with sheep pneumonia. This study was conducted to isolate and characterize the aerobic bacteria associated with pneumonia in sheep by conventional bacteriological methods. A total of 250 samples were collected from lungs of sheep with pathological conditions at El –Damazin Slaughterhouse. The pathological lesions included: congestion, fibrinous inflammation, pleural adhesions and abscesses. The isolates were identified by the standard bacteriological methods. Two hundred and two organisms were isolated from the 250 samples of which 100 (49.5%) were Gram- positive and 102(50.5%) Gram-negative bacteria. The gramnegative bacteria isolated were 20(10.9%) Mannheimia haemolytica, 15(7.6%) Pasteurella multocida, 13(6.4%) Citrobacter,11(5.4%) Klebsiella spp., 10(5.0%) Actinobacillus ligneirsii, 9(4.5%) Pseudomonas aeruginosa, 7(3.4%) Histophillus somni, (3.4%) Escherichia coli, 5(2.5%) Enterobacter spp. and 5(2.5%) Bordetella parapertussis. The Gram-positive isolates were 45(22.5%) Staphylococcus spp. 30 (14.9%) Streptococcus and Enterococcus spp. 17(8.8%) Corynebacterium pseudotuberculosis and 8(4.0%) Arcanobacterium (Actinomyces) pyogene.
