Prevalence of contagious bovine pleuropneumonia in Borno State, Nigeria
Epidemiological situation of contagious bovine pleuropneumoia (CBPP) over a ten (10) year period in Borno State of Nigeria was examined. During this period, 1,178 out of 355,745 cattle examined at postmortem had lesions suggestive of CBPP giving an overall prevalence rate of 0.33%. Highest prevalence rate of 0.77% was recorded in 1988 while lowest prevalence rate of 0.08% was recorded in 1994. Total vaccination coverage during the same period was 2,344,520 with highest vaccination coverage of 488,054 (10.8%) in 1988 and the lowest coverage of 66,398 (1.5%) in 1997. A total of 37 outbreaks of CBPP were reported during the period under review with highest outbreak (8) occurring in 1990. Seasonal prevalence of the disease was found to be highest in rainy season (0.20%) than the dry season (0.13%) but was not statistically significant (P>0.05). In a related development, a total of 3,875 cattle were examined between January and July 1998 in an attempt to find the incidence of CBPP using agar gel precipitation test (AGPT). Out of 57 suspected lungs, 41 (1.1%) were positive for AGPT. The disease is still endemic in Borno State and vaccination coverage was grossly inadequate.
