Cases of dermatophytosis caused by Trichophyton benhamiae var. luteum and T. europaeum, newly described dermatophytes within the T. benhamiae complex

Abstract

Trichophyton benhamiae var. luteum and T. europaeum -recently described dermatophytes within the T. benhamiae complex -were identified in nine cases of dermatophytosis involving guinea pigs, chinchillas and dogs. The diagnosis was obtained through direct hair/scale examination, culture and sequencing of the internal transcribed spacer region of ribosomal DNA.

A Case of Tinea Corporis Caused by Trichophyton benhamiae var. luteum from a Degu and Evolution of the Pathogen’s Taxonomy

“…Secondly, the pathogen has undergone taxonomic changes since it was classified as Trichophyton benhamiae in 2017 [1], with the recognition of the subspecies T. benhamiae var. luteum in 2020 based on morphological characteristics, notably yellow colony formation [2,3]. While these developments are rooted in mycological taxonomy, they may have far-reaching implications, particularly in light of the recent pet boom and the potential emergence of zoonotic dermatophytosis caused by zoophilic fungi.…”

Concurrent Chorioptic Mange and Dermatophytosis in Dairy Goats: A Case Report

“…Each zoophilic dermatophyte recognises a few animal species as primary hosts. The most important species are Microsporum canis, associated with cats, Trichophyton erinacei with hedgehogs, Trichophyton mentagrophytes with rabbits, and Trichophyton benhamiae with guinea pigs [7,11,12]. Trichophyton verrucosum is largely diffused as the causative agent of cattle ringworm [7,13,14], with enzootic situations commonly occurring in herds worldwide [8,[15][16][17].…”

Tinea corporis caused by Trichophyton benhamiae: report of the first case transmitted by guinea pig in Brazil

“…In addition to the guinea pig, transmission can occur through other animals, such as small rodents, rabbits, cats, dogs, and porcupines. 2 , 6 , 7 The first and only case of tinea corporis caused by T. benhamiae , reported in Brazil, was transmitted by a cat. 8 …”
