RESUMEN
Contagious bovine pleuropneumonia (CBPP) is a bacterial disease caused by Mycoplasma mycoides subsp. Mycoides. This disease affects ruminants mainly cattle with respiratory disorders as predominant symptoms. In Burkina Faso, this condition has been considered as enzootic since several years but data on its seroprevalence remains scares. This study aimed to establish the serological prevalence and determinants of CBPP in Burkina Faso in 2017. For this purpose, 3969 serum samples have been collected following a stratified sampling plan based on vaccination coverage in 12 regions, 84 communes, and 210 villages and analyzed using c-ELISA test. Individual seroprevalence was 16.91% (95% CI: 15.74-18.07%), while 84.5% (95% CI: 60.46-80.02%) of communes, chosen as epidemiological units were found positive. The individual prevalence was found to be associated with agro-ecological area (p < 0.05) and a prevalence of 18.70% (95% CI: 16.74-20.66%) was noted in Sahelian areas, while 15.79% (95% CI: 14.34-17.23%) was found in Soudanian areas. The prevalence was also significantly associated with vaccination coverage (p < 0.05) with a prevalence of 13.92% (95% CI: 11.66-16.18%), 19.21% (95% CI: 16.66-20.75%) and 11.61%(95% CI: 9.00-14.23%) for high, moderate, and low vaccination coverage respectively. The individual prevalence was respectively 16.97 (95% CI: 15.56-18.39%) and 17.13% (95% CI: 15.93-18.33%) for female and animals more than 2 years old. According to regions, the highest seroprevalence was found in Plateau Central region (38.18%, 95% CI: 29.1-47.26%), while the lowest was found in Centre-Est Region (7%, 95% CI: 4.5-9.5%). These prevalence data will allow us to adapt the ongoing strategy to control CBPP in Burkina Faso.
