Résumé
Brucellosis is a prevalent infectious zoonotic disease that affects humans, livestock, and wildlife in many parts of the world. A cross-sectional study was conducted to estimate the seroprevalence and risk factors of brucellosis among farmers and patients attending six health centers in Sidi Kacem province (northwestern Morocco). Blood samples (3-5 mL) were collected. Among 1283 participants, 351 were males and 932 were females and tested for Brucella antibodies using rose Bengal plate test and immunoglobulin (Ig)M/IgG enzyme-linked immunosorbent assay (ELISA) for confirmation. The seroprevalence of brucellosis was 33.20% (426/1283) with a higher risk among males and rural residents. The univariable analysis revealed that contacting cattle, handling abortion products and manure, and consuming undercooked beef and goat meat were all risk factors for brucellosis. Furthermore, raw milk and milk derivatives were risk factors strongly linked to brucellosis. Our findings indicate a high prevalence of brucellosis associated with the consumption of raw meat, raw dairy products, milk, and close contact with infected animals. However, there are some limitations to this study, such as we did not use the ELISA test on all sera collected and individuals under the age of 18 were not included in the study. Moreover, building a database on the occurrence of brucellosis and associated epidemiological factors is critical for providing informed advice to policymakers to improve control strategies against this disease in Morocco.

The seroprevalence of brucellosis was 33.20% (426/1283) with a higher risk among males and rural residents.

Our findings indicate a high prevalence of brucellosis associated with the consumption of raw meat, raw dairy products, milk, and close contact with infected animals. However, there are some limitations to this study, such as we did not use the ELISA test on all sera collected and individuals under the age of 18 were not included in the study. Moreover, building a database on the occurrence of brucellosis and associated epidemiological factors is critical for providing informed advice to policymakers to improve control strategies against this disease in Morocco.
