Dermatophilosis cases among MSM in Stockholm suggest sexual transmission of traditionally zoonotic pathogen
By
Karin Haij Bhattarai
Summary
This rapid communication from Eurosurveillance describes four microbiologically confirmed cases of dermatophilosis (caused by Dermatophilus congolensis) among men who have sex with men (MSM) in Stockholm, Sweden, between March and June 2026. All cases occurred in MSM using HIV pre-exposure prophylaxis (PrEP) and with no known animal contacts, challenging the traditional view of dermatophilosis as solely a zoonotic infection. The infections were likely acquired in Sweden, Japan, and Spain. The findings suggest possible sexual transmission within MSM networks and indicate that dermatophilosis may be under-recognised in sexual health settings.
