Contagious bovine pleuropneumonia is an important infectious disease of cattle caused by Mycoplasma mycoides subsp. mycoides and a major constraint to cattle production in sub-Saharan Africa. This study was aimed to identify pathological and histopathological lesions identified in cattle tentatively diagnosed with CBPP at Yola Modern Abattoir, Adamawa State. A total of 9,750 cattle were examined at post-mortem for a period of six months, 110 (1.13%) had lesions suggestive of CBPP out of which seventeen (17) were randomly selected and processed for histopathology based on standard laboratory protocols. Based on sex, CBPP lesion was observed more in female 63 (1.06%) than in the male 47 (1.24%). Whereas, CBPP lesions was observed highest in White Fulani breed 68 (1.14%) followed by Cross breeds 23 (91.16%) and Sokoto Gudali 19 (1.74%) and lowest in Red Bororo 10 (1.36%). There was insignificant statistical association (P>0.05) between CBPP lesions and sex and breed of cattle sampled. Age distribution of CBPP lesion was observed higher in cattle between ages of 4-7 years 79 (1.16%), followed by cattle of 1-3 years 28 (1.15%) and least in cattle less than 1 year 3 (0.60%) with significant statistical difference (P<0.05) between the age groups. Histopathology lesions observed include severe congestion of pulmonary blood vessel in all the lung tissues and fibrin exudation into inter-alveolar spaces with almost all the alveoli collapsed. The bronchiolar epithelium was observed to be thickened, hyperplastic and folded, with a considerable quantity of edematous fluid and numerous inflammatory cells seen in the lumen. In conclusion, this study had demonstrated the presence of CBPP lesions in cattle in the study area. Therefore, serological screening of all cattle, stamping out policies and aggressive annual vaccination campaigns are thus recommended in the study area.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
