Abstract

Contagious bovine pleuropneumonia is an important economic disease of cattle caused by Mycoplasma mycoides subspecies mycoides and manifested by anorexia, fever, dyspnoea, polypnoea, cough and nasal discharges. An eleven years (2006-2016) abattoir-based retrospective data were collated and analysed from Adamawa state Ministry of Livestock Production. Out of 241,700 cattle examined at post-mortem, 8,429 had CBPP-like lesions giving a prevalence of 3.49% (95% CI: 3.41-3.56). The overall prevalence for each local government area were 2.42% (95% CI: 2.35-2.49), 5.53% (95% CI: 5.30-5.74) and 8.97% (95% CI: 8.56-9.41) for Yola, Mubi and Ganye abattoirs respectively. There was   significant association (p<0.05) between Local Government Areas and occurrence of CBPP. The annual highest prevalence of 5.75% (95% CI: 5.43-6.09) was recorded in 2010 with 1,128 cases and lowest prevalence of 2.43% (95% CI: 2.23-2.66) was recorded in 2007 with 505 cases. Based on season, highest prevalence rate of 3.85% (95% CI: 3.58-4.14) was recorded in February with 709 cases and lowest prevalence rate of 3.03% (95% CI: 2.80-3.28) was recorded in December with 605 cases. Both annual and monthly prevalence rates varied significantly (p<0.05). It was concluded that CBPP is endemic and widespread in Adamawa state. Hence, we recommend increased funding in the control of the disease, restriction of cattle movement and provision of cattle ranches.
