Isolation of Trichophyton rubrum var. raubitschekii from a dog.

A rare anthropophilic dermatophyte, Trichophyton rubrum var. raubitschekii, was isolated for the first time from a case of animal dermatophytosis. We morphologically and physiologically identified the isolate from a case of canine dermatophytosis. Molecular typing of chitin synthase 1 ( CHS1) and ITS1-5.8S-ITS2 sequences suggest that human and canine isolates of T. rubrum and T. rubrum var. raubitschekii are genetically identical. Therefore, T. rubrum, including T. rubrum var. raubitschekii, might be pathogenic to humans and dogs. [ABSTRACT FROM AUTHOR]
