Circulating of Salmonella Strains in West Africa: Lacks of Surveillance and Research

---

Résumé

Salmonella is one of the main causes of diarrheal infections worldwide, particularly in tropical and subtropical regions. In West Africa, several Salmonella strains have been identified and characterised, revealing an alarming trend towards the emergence and spread of multidrug-resistant (MDR) strains. Despite this serious situation, epidemiological surveillance remains limited and insufficient on a national scale. The main transmission routes, particularly foodborne transmission, as well as inadequate hygiene and health-and-safety practices, play a significant role in the dissemination of these resistant strains within the region. This study aims to provide an up-to-date overview of salmonellosis in West Africa, focusing on antimicrobial resistance dynamics and the diagnostic and surveillance capabilities available. It also proposes alternative therapeutic and control strategies. This analysis is in line with the One Health approach, which is advocated as an integrative framework for multisectoral surveillance of antimicrobial resistance in tropical contexts, and for rationalising antibiotic use in human, animal and environmental health.
