Abstract

OBJECTIVES: To evaluate the performance of the ResistancePlus GC (beta) assay for the simultaneous detection of Neisseria gonorrhoeae and gyrA S91 markers of resistance (S91F) and susceptibility (WT) to ciprofloxacin, from both clinical specimens and isolates. METHODS: Performance was assessed on several sample banks, including N. gonorrhoeae isolates (n = 822), non-gonococcal isolates (n = 110), N. gonorrhoeae-positive clinical specimens (n = 402) and N. gonorrhoeae-negative specimens (n = 290). Results were compared with previous testing data, including S91 genotyping and phenotypic resistance profiles. RESULTS: Overall, the assay demonstrated 100% sensitivity for N. gonorrhoeae detection ..
