Evaluation of the viasure Neisseria gonorrhoeae ciprofloxacin resistant assay for the simultaneous identification and direct detection of ciprofloxacin susceptibility

Abstract

The detection of resistance without the need for culture is essential to establish a guided treatment against Neisseria gonorrhoeae (NG) infections. We evaluated the VIASURE Neisseria gonorrhoeae ciprofloxacin resistant Real Time PCR Detection Kit (CerTest Biotec S.L, Zaragoza, Spain) for the simultaneous identification and direct detection of ciprofloxacin susceptibility in 88 NG isolates and 133 positive NG clinical samples of different anatomical location. The sensitivity for NG detection was 93.2% and the specificity 100%. The sensitivity of the test to characterize resistance/susceptibility to ciprofloxacin was (96.5%). In conclusion, the test evaluated is suitable for use to establish a targeted therapy with oral ciprofloxacin in case of not detecting resistance.
