## Executive GIST (TL;DR)
- Trichophyton indotineae is an emerging **dermatophyte** frequently resistant to terbinafine, an antifungal commonly used for dermatophyte infections. - Investigators analyzed identification data generated by the Mass Spectrometry Identification (MIND) global network to monitor occurrences of this pathogen. - Data from 2022–2025 showed a **threefold increase** in identifications of T. indotineae, indicating notable global spread over that period. - The study concludes that a mass spectrometry–based identification network is an effective surveillance tool for tracking the global dissemination of this dermatophyte. - Keywords associated with the report include **antifungal drug resistance**, dermatophyte infection, mass spectrometry, public health surveillance, and fungal skin diseases. - The article is published in Emerging Infectious Diseases (2026 Sep;32[9]:1487–1491) and is available as a free article; DOI 10.3201/eid3209.260463. - Specific methodological details (sample numbers, geographic breakdown, laboratory procedures, or resistance prevalence beyond terbinafine association) were not reported in the abstract provided.

We analyzed data produced by the Mass Spectrometry Identification global network. Those data revealed a 3-fold increase in T. indotineae identification during 2022-2025, demonstrating that this application is an effective tool for monitoring global spread of this pathogen. **Keywords:** France; antifungal drug resistance; antimicrobial resistance; dermatophyte infection; fungal skin diseases; fungi; mass spectrometry; public health surveillance; sexually transmitted infections; zoonoses.
