“…In Chinchillas, the occurrence of ringworm is unusual, and similar to other rodent species, ringworm is commonly caused by Trichophyton mentagrophytes (Quinn et al, 2004;Mans & Donnely, 2012) and Microsporum gypseum (Mans & Donnely, 2012;Morganti & Gomez Portugal, 1970), and T. mentagrophytes is a fungus typically isolated in healthy rodents skin (Donnelly et al, 2000).…”

-Long-tailed chinchillas are rodents popularly bred as pets for being a docile animal; however, in the natural environment, it is a critically endangered species. This study reports the occurrence of ringworm in Chinchilla lanigera. A female specimen presenting an alopecia-oval lesion on the left cheek was send for clinical care. On examination, the lesion was positive for the Wood test and on the hematological evaluation, and in the mycological assessment was performed and Microsporum canis was isolated after 10 days of incubation on Sabouraud Dextrose Agar. The animal was treated with topical solution of chlorhexidine and iodopovedine, hydrocortisone ointment and terbinafine cream. Ringworm is an uncommon infection in rodents and M. canis is a commensal fungus of the skin of dogs, being a parasite primarily zoophilic but can cause injury to humans. Ringworms are uncommon in rodents, being attributed in this report to stress associated to indirect contact with canine material contaminated with the fungus.Keywords: Dermatology; exotic animals medicine; mycosis; pets; rodents.RESUMO -Chinchilas são roedores popularmente criados como animais de estimação por ser um animal dócil, porém em ambiente natural é uma espécie criticamente ameaçada de extinção.

“…Ringworm caused by T. mentagrophytes var. erinacei has been reported in wild European hedgehogs, clinically characterized by crusty lesions, alopecia, and loss of spines, mainly affecting the head area [17]. In Britain, Morris and English [9] reported a prevalence of 19.8% (39/203) of T. mentagrophytes var.…”

Integument Mycobiota of Wild European Hedgehogs (Erinaceus europaeus) from Catalonia, Spain

et al. 2012

There are some reports about the risk of manipulating wild hedgehogs since they can be reservoirs of potential zoonotic agents like dermatophytes. The aim of this study was to describe the integument mycobiota, with special attention to dermatophytes of wild European hedgehogs. Samples from spines and fur were cultured separately in Sabouraud dextrose agar (SDA) with antibiotic and dermatophyte test medium (DTM) plates. Nineteen different fungal genera were isolated from 91 cultures of 102 hedgehogs. The most prevalent genera were Cladosporium (79.1%), Penicillium (74.7%), Alternaria (64.8%), and Rhizopus (63.7%). A lower prevalence of Aspergillus (P = 0,035; χ 2 = 8,633) and Arthrinium (P = 0,043; χ 2 = 8,173) was isolated during the spring time and higher frequencies of Fusarium (P = 0,015; χ 2 = 10,533) during the autumn. The prevalence of Acremonium was significantly higher in young animals (70%, 26/37) than in adults (30%, 11/37) (P = 0,019; χ 2 = 5,915). Moreover, the majority of the saprophytic species that grew at the SDA culture were also detected at the DTM. Finally, no cases of ringworm were diagnosed and no dermatophytes spp. were isolated. Concluding, this study provides the first description of fungal mycobiota of the integument of wild European hedgehogs in Spain, showing a large number of saprophytic species and the absence of dermatophytes.

“…Furthermore, some use a species definition based on morphological differentiation, and more recently by genetic sequencing techniques. 6,9,10 The most common small mammal dermatophytes are Trichophyton mentagrophytes 7,11,12 , T. erinacei 13 , Microsporum gypseum, 1,14 and less often M.…”

“…1 Zoophilic fungi invading skin, hairs, nails, and spines lead to the formation of erythema, excoriations, crusts, hyperkeratosis, alopecia, and often secondary bacterial dermatitis (Beck 1998). This skin condition is referred to as dermatophytosis or dermatomycosis, a common disease in household pets, especially small mammals living in close proximity to humans.…”
