Abstract

Contagious bovine pleuro-pneumonia (CBPP) is an endemic disease in Nigeria, mostly affecting cattle. Despite the endemic status of CBPP in Nigeria, there is a dearth of information on the clinicopathological manifestations of the disease in Sokoto Gudali breed of cattle, hence the need to highlight our findings in this report. The carcass of 11-month-old Sokoto Gudali heifer was presented for necropsy with a history of respiratory distress amongst the herd. A detailed postmortem examination was conducted, and representative tissue sections collected for histopathologic tissue processing. Swabs of the lung tissue and pleural effusion were also collected for bacteriology. A farm visit to assess and manage the disease within the herd was also carried out. Nasal swabs and blood samples were also collected for bacteriological and haematological analyses. Necropsy revealed marked fibrinous effusion in the pleural cavity, fibrinous consolidation of the left lung, and chronic pneumonia of the right lung. Clinical observations of the herd made on farm visit included emaciation, cough, nasal discharge, anorexia and fever in some of the heifers. Haematological analysis of the blood samples revealed anaemia and leukopenia due to neutropenia. Histopathological analysis of samples from the left lung revealed acute fibrinous pleuro-pneumonia whereas analysis of the right lung revealed chronic interstitial pneumonia. Microbial culture of the pleural effusion and nasal swab yielded growths of Mycoplasma mycoides subspecies mycoides (Mmm) colonies. Consequently, the sick heifers were culled while others were treated with enrofloxacin and tetracycline injections. The burden of CBPP in cattle in Nigeria is enormous and discourages investments in the livestock sector thereby thwarting efforts to meet the protein requirements of the growing population.
