Dermatophilosis is considered a zoonotic infection. We report 9 cases among men who have sex with men in Barcelona, Spain, during December 2025-March 2026. Whole-genome sequencing revealed highly related isolates forming a distinct lineage within the genus Dermatophilus. Epidemiologic and clinical features of the cases support human-to-human transmission via sexual contact.
