Abstract

The present study describes the occurrence of dermatophytes and their antifungal susceptibility in healthy rabbits kept on a farm or in a household as companion animals. Out of 614 animals examined, 146 samples (23.78%) were positive for dermatophytes by direct microscopic examination, and the dermatophytes were isolated from 112 samples (112/146, 76.71%). The four predominant species of dermatophytes isolated from healthy rabbits were Trichophyton mentagrophytes (37.5%), Microsporum gypseum (25%), Microsporum nanum (21.43%) and Microsporum canis (16.07%). The kits younger than 6 months of age showed a relatively higher occurrence rate, and male animals showed significantly higher occurrence than the females (P<0.05). Occurrence of dermatophytes in the studied rabbits was higher in summer and autumn than in spring and winter (P<0.05). Itraconazole (0.03-0.5 μg/mL), ketoconazole (0.06-0.5 μg/mL), miconazole at 0.03-0.5 μg/mL and 0.03-.25 μg/mL concentrations showed the lowest MIC values against T. mentagrophytes, M. canis, M. nanum and M. gypseum, respectively. However, fluconazole and griseofulvin showed the highest MIC value against the isolates, indicating antifungal resistance.
