Geographic distribution of Trichophyton indotineae spectra in study of global spread of T. indotineae tracked by the Mass Spectrometry Identification (MSI) Network, 2022–2025. Maps indicate global (A) and European (B) distribution of T. indotineae spectra obtained using the online MSI application during March 31, 2022–December 31, 2025. Circle size is proportional to the number of spectra identified per center (1–301 spectra). Maps were generated with mapchart (https://www.mapchart.net) and Flourish (https://flourish.studio).
