While dermatophytoses of several animal species have been extensively investigated, information on their occurrence and epidemiology in rabbits is limited. We carried out a study from October 2006 to February 2007 of 23 rabbit farms in Apulia and Basilicata regions (southern Italy) in order to investigate the occurrence and risk factors associated with dermatophytoses in breeding rabbits. Dermatophytes were isolated from 86.9% (20/23) of the farms and from 51.8% (420/810) of the animals sampled. Trichophyton mentagrophytes (47.9%) and Microsporum canis (3.2%) were isolated from diseased (71.7%) and healthy (48.4%) animals as well from the surrounding environment (7.5%). The occurrence of lesions, the age of rabbits, and farm management (e.g., temperature, humidity and methods and frequency of disinfection practices) were identified as the most significant risk factors (P < 0.05) for the occurrence of dermatophytes. Animals in fattening and finishing stages were the most frequently infected (i.e., 58.2 and 61.6% respectively). Dermatophyte prevalence was significantly (P < 0.05) higher in areas with higher temperature (>20°C) and relative humidity ranging from 62-65%. The results of the present investigation suggest that zoonotic dermathophytes are present in rabbit farms and highlight the importance of correct management procedures for the control of the infections.
