Abstract
Background: In Central Africa, it is difficult to fight against antibiotic resistance, because of  a  lack of data and information on bacterial resistance, due to the low number of studies carried out in the field. To fill this gap, we carried out a systematic review of the various studies, and devise a molecular epidemiology of antimicrobial resistance from humans, animals and the environmental samples.Method: A systematic search of all publications from 2005 to 2020 on bacterial resistance in Central Africa was performed on Pubmed, Google scholar and African journals online. All circulating resistance genes, prevalence and genetic carriers of these resistances were collected. The study area was limited to the 9 countries of Central Africa. Results: Five hundred seventeen studies were identified through a literature search, and sixty studies carried out in 8 countries were included. Among all articles included, 43 articles were from human. Our study revealed not only the circulation of beta-lactamase and carbapenemase genes, but also several other types of resistance genes. To finish, we noticed that some studies reported mobile genetic elements such as integrons, transposons, plasmids, or chromosomes.Conclusion: The scarcity of data poses difficulties in the implementation of effective strategies in the fight against antibiotic resistance, which requires a health policy in a "One Health" approach.
