Sexually transmitted enteric infections among men who have sex with men in southern Taiwan: a molecular surveillance study

Background: Sexually transmitted enteric infections (STEIs) are increasingly recognized among men who have sex with men (MSM), yet contemporary surveillance data from Asia remain limited.We conducted a molecular surveillance study to characterize the burden, clinical features, and associated factors of STEIs among MSM in southern Taiwan.and insertive anal sex (aOR 3.2) were independently associated with GI panel positivity.Shigella was associated with prior syphilis and concurrent Campylobacter detection.Co-detection of enteric and sexually transmitted pathogens was observed in 21% of 107 pathogen-positive participants. Conclusions:This study provides comprehensive, molecular surveillance of STEIs among MSM in Asia and reveals a significant burden of frequent co-detection with conventional sexually transmitted infections.Rectal lymphogranuloma venereum (LGV) had different co-infection patterns compared with non-LGV genotypes.Our findings highlight the need for integrating enteric pathogen surveillance into comprehensive sexual health frameworks for MSM.
