    Abstract

    This retrospective study deals with the main samples studied at the Mycology Diagnostic Service of the Faculty of Veterinary Science of Barcelona; animals with suspected dermatophytosis. Over a ten-year period from 1986 to 1995, 136 dermatophytes were identified from dog and cat cultures submitted for identification and from specimens submitted for mycological examination from a variety of other domestic animals. The most frequent dermatophytes isolated were Microsporum canis (55.9%), Trichophyton mentagrophytes var. mentagrophytes (27.2%), Microsporum gypseum (7.4%) and Trichophyton verrucosum (7.4%). The identity of the dermatophytes from dog and cat cultures submitted for identification was M. canis (77.8%), T. mentagrophytes (13.3%) and M. gypseum (8.9%). Dermatophytes were cultured from 15 of 105 (14.3%) canine specimens and 19 of 56 (33.9%) feline specimens submitted for mycological examination during this period. Microsporum canis was the most common species isolated (73.3% and 94.7% respectively). The percentage of positive microscopic examinations of the specimens of hair in culture positive submissions from dogs and cats was 58.8%. There was a high proportion of positive cultures from both dogs and cats less than 1 year of age, and in some breeds of dogs, but there was no significant difference between the sexes. Although dermatophytes were more frequently isolated in autumn and winter months, no significant difference was detected in the seasonal distribution of the canine and feline dermatophytosis. Trichophyton mentagrophytes was the most prevalent dermatophyte in rabbits and T. verrucosum in ruminants. Other isolated species were T. equinum and M. equinum from horses.
