Abstrakt: Objective: The global emergence of drug resistance in Neisseria gonorrhoeae has resulted in the use of a range of antibiotics and is now a public health concern because this pathogen may become untreatable in the future. This study aimed to detect antimicrobial-resistant determinants in N. gonorrhoeae directly from endocervical specimens.
Methods: Three hundred seven pregnant women were enrolled in this study. Endocervical swabs were collected from consenting women and used for the detection of N. gonorrhoeae. Molecular indicators associated with penicillin, tetracycline, ciprofloxacin, azithromycin, spectinomycin, cefixime, and ceftriaxone resistance were detected by polymerase chain reaction.
Results: Of the 307 women, 24 (7.8%) tested positive for N. gonorrhoeae. The tetM gene carried on the American-type plasmid was shown to be present in all the specimens. Approximately 87.5% of the specimens carried the penicillinase-producing African-type plasmid, and the gyrase A gene carrying the Ser-91 mutation was shown to be present in 37.5% of the specimens. Mutations associated with azithromycin, spectinomycin, cefixime, and ceftriaxone resistance were not detected in the study specimens.
Conclusion: The detection of resistance determinants without the need for culture may prove to be more feasible for future epidemiological investigations focused on tracking antimicrobial susceptibility patterns in N. gonorrhoeae.
