Extensive Dermatophytosis Caused by Terbinafine-Resistant Trichophyton indotineae, France

Emerg Infect Dis. 2022 Jan;28(1):229-233. doi: 10.3201/eid2801.210883.

Abstract

Extensive dermatophytosis caused by terbinafine-resistant Trichophyton indotineae harboring Phe397Leu and Leu393Ser substitutions in the squalene epoxidase enzyme was diagnosed in France. Analysis of internal transcribed spacer sequences revealed the wide spread of this species in Asia and Europe. Detection of T. indotineae in animals suggests their possible role as reservoirs.

Keywords: France; Trichophyton indotineae; antimicrobial resistance; dermatophytosis; fungi; genotype VIII; ringworm; skin conditions; squalene epoxidase; terbinafine; zoonoses.
