The present study aimed to synthesize available evidence on colistin resistance in Algerian poultry, poultry-associated environments, and chicken meat from 2015 to July 2026. PubMed was used as the primary bibliographic database for publications from 1 January 2015 to 15 July 2026. The reference lists of eligible studies were checked, and relevant publisher and journal websites were examined. Eleven studies met the final eligibility criteria. The available evidence indicated that colistin resistance and mobile colistin resistance genes, particularly mcr-1, have been documented in diseased poultry, apparently healthy poultry, poultry-farm environments, and retail chicken meat in Algeria. The mcr-5 gene has been reported in apparently healthy poultry, while some studies have documented phenotypic colistin resistance without confirming mcr-1. In avian pathogenic Escherichia coli, colistin resistance and mcr-1 were reported alongside multidrug-resistance and virulence-associated markers. However, substantial heterogeneity in the sampled populations, study designs, geographical coverage, and susceptibility-testing methods limited the ability of the studies from Algeria to estimate the national prevalence of colistin resistance or mcr carriage, or to infer the direction of transmission among poultry, food, and environmental compartments. https://jwps.rovedar.com/index.php/JWPS/article/view/139 Antimicrobial resistance Colistin Escherichia coli Mobile colistin resistance Poultry
