Neisseria gonorrhoeae resistant to quinolones (QRNG) becomes a very important problem in public health due to the development of rapid resistance to quinolones, which is why the WHO recommends reinforcing antimicrobial resistance monitoring to guide treatment. In Peru there are few reports on QRNG surveillance and still less work related to mutation patterns. This study aims to find mutations in the Determinant Region of Quinolone Resistance (QRDR) of the gyrA gene of N. gonorrhoeae from 1096 clinical samples of urine and swabs from 367 men who have sex with men (MSM) collected during the period 2012-2013. We detected 58 N. gonorrhoeae positive samples in 45 MSM by means of the APTIMA Combo 2 assay, and 11 QRNG positive samples of 11 MSM by Real Time PCR. The quinolone-resistant bacteria were analyzed by sequencing and we identified that the frequent mutation pattern was the double mutat...

Neisseria gonorrhoeae resistente a quinolonas (QRNG) es un problema muy importante en salud pública por su rápido desarrollo de resistencia a quinolonas, por lo que la OMS recomienda reforzar la vigilancia de resistencia antimicrobiana para orientar el tratamiento. En Perú hay pocos reportes sobre vigilancia de QRNG, y menos aún trabajos relacionados a patrones de mutación. Este estudio busca encontrar mutaciones en la Región Determinante de Resistencia a Quinolonas (QRDR) del gen gyrA de N. gonorrhoeae a partir de 1096 muestras clínicas de orina e hisopados, colectadas entre 2012 y 2013, provenientes de 367 hombres que tuvieron sexo con hombres (HSH). Se detectaron 58 muestras positivas a N. gonorrhoeae en 45 HSH mediante el ensayo de APTIMA Combo 2, y 11 muestras positivas a QRNG de 11 HSH mediante PCR en Tiempo Real. Las bacterias resistentes a quinolonas fueron analizadas por ...
