Our aim was to determine if there was a difference in culture positivity for oropharyngeal gonorrhoea when sampling using a nylon-flocked versus cotton-tipped swab. We collected FLOQSwabs and cotton-tipped swabs from individuals aged ≥ 18 years who had untreated oropharyngeal gonorrhoea detected by NAAT between November 2019-June 2020.Of 78 participants, 32 (41.0%) were culture-positive for N. gonorrhoeae from either swab. Of these 32, 29 (90.6%, 95%CI: 75.0%-98.0%) were positive on both swabs, one (3.1%, 95%CI: 0.0%-16.2%) tested positive on FLOQSwab only and two (6.2%, 95%CI: 0.1%-20.8%) tested positive on cotton-tipped swabs only. There was moderate agreement between the swabs in the amou..View full abstract
