“…Bacterial resistance is observed when antibiotics are used abundantly, and the bacteria undergo a strong selection pressure [ 6 ]. In modern poultry farms, antibiotics are often used for therapeutic, preventive, or growth-stimulating purposes, creating a favorable environment for the development of antibiotic resistance [ 7 , 8 ]. Escherichia coli is a bacterium found in the microflora of poultry and is one of the most frequently encountered bacteria in poultry farming, wherein it causes economic losses due to colibacillosis [ 9 ].…”

Background and Aim: Antimicrobial resistance (AMR) is a serious challenge to animal and human health worldwide. Therefore, this study aims to determine levels and patterns of AMR of Escherichia coli and Salmonella spp. strains isolated from poultry farms in Côte d'Ivoire. Materials and Methods: A cross-sectional study was conducted in two districts of Côte d'Ivoire with high poultry production: Abidjan and Agnibilékrou. A total of 231 fecal samples were collected in 124 poultry farms in both districts. Enterobacteria were isolated and tested for susceptibility to 14 antimicrobial agents using the disk-diffusion method. Results: A total of 212 E. coli and 36 Salmonella strains were isolated. In Abidjan, 139 collected samples generated 101 E. coli and 23 Salmonella strains, whereas in Agnibilékrou, 92 collected samples generated 111 E. coli and 13 Salmonella strains. Variable resistance levels were recorded for the antibiotics tested. The resistance prevalence of E. coli and Salmonella, respectively, was high: Doxycycline (98%/94%), sulfonamide (84%/86%), trimethoprim-sulfamethoxazole (80%/41%), and streptomycin (71%/52%). Average resistance rates were recorded for flumequine (38%/66%), ampicillin (49%/33%), amoxicillin (25%/44%), colistin (26%/2%), chloramphenicol (21%/2%), and gentamicin (4%/47%). The antibiotics least affected by resistance were cefuroxime (4%/5%), ceftriaxone (2%/0.00%), and nitrofurantoin (1%/0.00%). Conclusion: In this study, it was observed that resistance to important antibiotics is emerging in poultry production in Côte d'Ivoire. Policies promoting the rational use of antibiotics should be implemented to manage antibiotic resistance in animal production.

> Enterococcus faecium a développé une multirésistance aux antibiotiques dont les glycopeptides. Les glycopeptides (vancomycine et teicoplanine) agissent sur les entérocoques en se fixant sur les précurseurs de la paroi bacté-rienne dont ils empêchent ainsi la formation. La résistance est due à l'acquisition d'un opé-ron de gènes coopérant pour synthétiser des précurseurs sans affinité pour les glycopeptides. Des épidémies sont survenues récemment en milieu hospitalier dues à des souches de E. faecium appartenant à un complexe clonal (CC17) adapté à l'hôpital. Les épidémies peuvent être contrôlées par des mesures appropriées et de nouveaux antibiotiques qui sont disponibles. La dissémination de souches adaptées aux conditions hospitalières nécessite leur surveillance étroite. < Centre national de référence de la résistance aux antibiotiques, Laboratoire associé entérocoques, service de microbiologie,
