Evaluation of Bacterial Pneumonia and Pathological Changes in Lungs of Cattle Slaughtered in Maiduguri Central Abattoir, Borno State Nigeria

The study was designed to determine level of lungs inflammation and associated bacterial flora that influenced gross and histopathological lesions related to bovine pneumonic lungs amongst cattle slaughter in Maiduguri central abattoir. The study was conducted in Maiduguri, North-Eastern Nigeria. A total of 100 pneumonic lungs sampled from cattle slaughtered at Maiduguri central abattoir, 63 (63 %) were positive isolate and 37 were negative isolate (37 %). The results indicate isolates recovered were gram-positive and gram-negative bacteria with five bacterial genera isolated consist of 3 Gram-positive and 2 Gram-negative bacteria. The isolates were subjected to sensitivity test of various antibiotics like Ciprofloxacin, Pefloxacin, and Oflaxacinm and they were sensitive, while Chloramphenicol, Ciprofloxacin, Gentamicin, Streptomycin and Oflaxacin were Intermediate and Amoxicillin, Erythromycin, Cotrimoxazole, Gentamycin, and Ceftriaxone were resistance to the antimicrobial sensitivity tests. Pneumonic bacteria isolates based on sex and age of the cattle slaughtered at Maiduguri abattoir were recorded. Bull has the highest 58 (92.0%) compare to the cow 5 (8.0%). While age-wise, Isolates were recorded with highest 97.0 % among adult cattle when compare to the young cattle (3.0%). Three types of pneumonia were identified based on the Pathological examinations of 25 pneumonic lungs randomly selected from the 100 lungs samples which were recorded.
