The monitoring of antimicrobial resistance has become a priority, mainly in developing countries, to control the emergence of multidrug-resistant bacterial strains. This study evaluated the antibiotic resistance profiles of bacteria isolated at the National Institute of Hygiene in Togo. The laboratory records from January 2013 to December 2015 were examined, which showed that a total of 33,147 samples had been analyzed. Among them, vaginal swabs and urine samples were predominant, amounting to 38.17% and 33.24%, respectively. In total, 3,497 Gram-positive and 1,970 Gram-negative bacterial strains were cultured. Enterobacteriaceae (57.6%), Staphylococcus spp. (21.1%), and Streptococcus spp. (10.5%) were primarily isolated. The records showed that over 3 years, Escherichia coli was resistant to piperacillin (79.66%, 75.1%, and 83%), trimethoprim/sulfamethoxazole (79.3%, 82%, and 82.8%), ticarcillin (89%, 89.7%, and 93%), and amoxicillin (94.1%, 94%, and 96.09%), whereas Staphylococcus aureus was resistant to penicillin G. Streptococcaceae isolates were resistant to trimethoprim/sulfamethoxazole (78.11–87.1%), tetracycline (82.2–91.16%), and norfloxacin (86.16–94.3%). Escherichia coli and S. aureus isolated from urine were more resistant to antibiotics than those isolated from vaginal swabs. There is a need to develop new strategies to fight the emergence of multi-resistant bacteria in Togo.
