Prevalence study in Cameroon identifies Brucella abortus as the endemic species in livestock

Brucellosis is a neglected zoonotic disease impacting agricultural economies, as well as animal and human health globally. In sub-Saharan Africa, brucellosis is considered endemic in many countries based on serological evidence, although the presence and distribution of specific Brucella species remain unverified due to limited bacteriological confirmation. Due to the economic importance and national/international trade routes, this study investigated Brucella prevalence in cattle, sheep, goats, and pigs from slaughterhouses in the Far-North, North, and West regions of Cameroon. The study emphasizes the critical need for coordinated surveillance systems to support evidence-based control strategies, enhance disease monitoring, and reduce the risk of transboundary transmission.
