Suspected Sexual Transmission of Dermatophilosis among Men Who Have Sex with Men, Lyon and Paris, France, 2025–2026

We report a genomically linked cluster of 9 Dermatophilus congolensis cutaneous infections diagnosed within 2 months among men who have sex with men in Lyon and Paris, France, 2025-2026. Genomic similarity and shared sexual exposures strongly suggest interhuman sexual transmission of this zoonotic bacterium.

Abstract

We report a genomically linked cluster of 9 Dermatophilus congolensis cutaneous infections diagnosed within 2 months among men who have sex with men in Lyon and Paris, France, 2025-2026. Genomic similarity and shared sexual exposures strongly suggest interhuman sexual transmission of this zoonotic bacterium.
