Background: Brucellosis is a major zoonosis with negative consequences on the health, economic and social in countries with agricultural and livestock. Moreover, it is one of the 5 priority zoonosis monitored in Burkina Faso as part of the fight against major epidemics with a multisectoral approach “One Health” involving The Ministry of Health, Agriculture, Animal and Fisheries Resources and the Environment. In Burkina Faso, despite its presence in animals, its prevalence is still unknown among people at risk. The general objective of this study is to describe the seroepidemiology characteristics and risk factors for brucellosis in people in direct and close contact with pigs and their feces in the city of Bobo-Dioulasso in Burkina Faso.

Methods: The aim was to find anti-Brucella antibodies in the serums of persons in contact with pigs through serological tests of the Buffered Antigen Test and the Enzyme-Linked Immunosorbent Assay. Through a questionnaire, we investigated the epidemiological characteristics and risk factors related to the presence of these antibodies. The study was conducted from August 20, 2016 to October 24, 2021. It concerned anyone in direct and close contact with pigs and their feces and residing within a 25 km radius of the city center of Bobo-Dioulasso.

Results: Of 368 sera, seroprevalence with the Buffered Antigen Assay and the Enzyme-Linked Immunosorbent Assay gave respectively 10,9% and 8.2%. Subjects over 35 years of age were seropositive at 14.1%, those 18 - 35 years of age at 3.8%. Men were 10.8% and women 1.8% seropositive. Regarding the profession, the slaughterhouse workers were seropositive at 12%. Seropositivity was significantly associated with risk behaviors such as: abortion assistance (p = 0.01), manipulation of the unborn (p = 0.01) and permanent contact with unprotected pig blood (p = 0.01).

Conclusion: The presence of anti-Brucella antibodies was revealed in people in direct and close contact with pigs and their feces in the city of Bobo-Dioulasso. In view of this result and the major nature of this zoonosis, it is imperative to conduct a survey within other at-risk occupations in order to diagnose and eliminate the enabling factors.
