Survey of Zoonotic Dermatoses in Client‐Owned Exotic Pet Mammals in Southern Italy

Abstract

Several 'exotic' mammalian species (e.g. rabbits, rodents, ferrets and hedgehogs) live in close proximity to humans as companion pets. Skin diseases (SD) are frequent causes of morbidity in exotic pet mammals, and most of those SDs have a zoonotic potential. The purpose of this study was to determine the frequencies and types of zoonotic dermatosis (ZD) in client-owned, exotic pet mammals in Southern Italy. Six-hundred and fifty-five medical records of exotic pet mammals examined between 2011 and 2012, across twenty private practice veterinary clinics around the Naples area (Italy), were retrospectively evaluated and screened for animals diagnosed with SDs (rabbits n = 455, guinea pigs n = 93, ferrets n = 64, hedgehogs n = 19, chinchillas n = 13 and rats n = 11). The records of animals diagnosed with SD, whose causative agents had a zoonotic potential, were selected for analysis. The Mann-Whitney independent test was used for statistical analysis. A P value ≤ 0.05 was considered statistically significant. Eighty-two records (12.5%) of animals with ZD were identified. Of those, 56.1% (46/82) were affected by fungal infections and 42.7% (35/82) by parasitic infections. No zoonotic bacterial or viral infections were diagnosed. Dermatophytosis was significantly diagnosed more frequently in younger animals. The results of this survey indicate that exotic pet mammals may serve as active carriers for many highly contagious pathogens with zoonotic potential. Awareness and vigilance by the veterinary practitioner is crucial in the prevention of occurrences of ZDs. Children frequently come in close contact with exotic pets. To prevent the unplanned transmission of pathogen from pet to human, an active routine screening examination and preventative treatments are strongly recommended for every newly purchased pet mammal.
