The present study was conducted in order to elucidate the asymptomatic carrier state of dermatophytes on the laboratory rodents in Korea during the period from August 1986 to April 1987. A total of 988 laboratory rodents, comprising 393 albino rats, 285 albino mice, 238 guinea pigs and 72 hamsters, were randomly selected for the isolation of dermatophytes from 6 research institutes and 2 breeding farms. And the mating experiments were performed to identified the perfect states of Trichophyton mextagrophytes isolated from albino rats. Dermatophytes were recovered from 94 of 393(23.9%) albino rats and from 3 of 5 colonies. Isolation rate of each colony was 38.4%, 32.0% and 9.8%, respectively, and the albino rats over 2 months old(28.2%) were higher than below 2 months old(2.9%) in the isolation rate of dermatophytes. Among 94 strains of dermatophytes isolated from albino rats, all the strains were identified T mentagrophytes, except 1 strain of Microsporum gypseum, and its perfect states were Arthroderma $vanbreuseghemii^+$.
