This was a descriptive cross-sectional study of antibiotic susceptibility test reports for Enterobacteriaceae strains isolated from biological samples at the INH bacteriology laboratory from January 2020 to February 2025. Using R software, resistance rates were estimated with a 95% confidence interval (95% CI).
A total of 22,960 samples were analyzed at the bacteriology laboratory. Urine and pus samples were predominant, accounting for 75.04% and 16.5% of the total, respectively. Cultures were positive for 3,198 samples, including 2,128 Gram-negative bacterial strains and 1,070 Gram-positive bacterial strains. Enterobacteriaceae (66.5%). Escherichia coli was resistant to piperacillin at rates of 85.36%, 82.5%, 66.67%, 68.0%, and 100%, respectively, from 2020 to 2024. This represents an acquired resistance rate of 14.36%. Trimethoprim/sulfamethoxazole resistance was 80.95% and 87.96% in 2020 and 2024, respectively; norfloxacin resistance increased by 13.14% between 2020 and 2024. Klebsiella pneumoniae was resistant to ciprofloxacin at 35.7% in 2020 and 40.6% in 2024, and to ofloxacin at 39.2% in 2020 and 40.75% in 2024. Only cefoxitin (90.38%) and imipenem (98.6%) still retain activity against the isolated Enterobacteriaceae strains. The production of penicillinases and extended-spectrum beta-lactamases (ESBL), was observed in 91.31%, and 74.93% of Enterobacteriaceae strains, respectively.
The phenomenon of antibiotic resistance is real, with only a small proportion of Enterobacteriaceae strains isolated still susceptible to antibiotics. Extending this study to several healthcare facilities in Togo and communicating with infectious disease specialists are essential to help adapt treatment protocols for infections.
