“…Dermatophytosis is an important public health problem worldwide [ 14 , 19 ]. It is the most frequent dermatologic problem confronting veterinarians because it affects a wide range of domestic and wild animals [ 14 , 20 ]. Dermatophytes are involved in various fungal infections that dermatologists and veterinarians are called upon to treat [ 18 ].…”

Wild animals are an important component of the ecosystem, and play a major role in it. However, in recent years, there has been an astronomical increase in the incidence of wildlife mycotic diseases leading to wildlife extermination. It is important to note that most of these mycotic diseases are zoonotic, and since there is a lot of attention given to zoonosis of a bacterial or viral origin in recent times, it is important to look into the mycotic diseases which may have zoonotic potential. Previously, the authors expatiated on some major wildlife mycotic diseases. In this review, we shed light on the etiology, epidemiology, diagnosis, pathogenesis, pathogenicity, macroscopic and microscopic pathology, and hematological and serum biochemical findings of dermatophytosis, coccidioidomycosis, blastomycosis, and sporotrichosis, which are very important mycoses of wildlife.

“…Soil of various habitats of Kanpur city were studied for occurrence of keratinophilic fungi; indoor environment [6][7], house dust [8][9], birds [10], house sweeping dust, sand [11][12][13], potted indoor plant [14], parks [15] aquatic habitats [16] and sewage slug [17] Few other recent reports of occurrence of keratinophiles from India and other parts of Worlds are Hilly soil [2], Ladak [18], Sewage sludge of Vishakhapatnam [19], Vidarbha region of Maharashtra [20], poultry site of Shivamogga Karnataka [21], predatory birds [22], Parks of Jaipur [23]. Climate and keratinous waste in environments make Kanpur city appropriate study area.…”

Kanpur is a city which has huge number of leather product units and leather processing plants. These units are one of major contributors of keratinous waste and produces keratinous material as waste in the form of hairs, hides, dermis. During the present study 83 keratinophilic fungi were isolated from 40 soil samples of urban waste and cattle field habitat of various localities. From 20 samples of urban waste, 44 keratinophilic fungi were isolated, 39 fungi recorded from Cattle field. The frequency of genera Chrysosporium was recorded in urban waste (29.54%) and cattle field soil (20.51%). Maximum (13.83%) frequency was recorded in the case of Chrysosporium indicum in urban waste.

“…Dermatophytosis is a superficial fungal infection of the stratum corneum of the epidermis and keratinized tissues including the skin, hair and nails of humans and animals. It is considered as the most commonly encountered fungal infection in veterinary practice affecting a wide range of domestic and wild animals (1,2,3), and is recognized as a major skin disease of zoonotic importance (4,5). Dermatophytosis is caused by a unique group of fungi known as the dermatophytes which can be categorized into one of three genera; Trichophyton, Microsporum and Epidermophyton.…”

Background: Dermatophytosis (ringworm) is a zoonotic fungal skin infection caused predominantly by Microsporum canis, Microsporum gypseum and Trichophyton spp. It is highly transmissible and, while normally self-limiting, could be problematic due to its potential to cause disease in certain human populations. The occurrence and associated risk factors of dermatophytoses in dogs presented at three veterinary clinics in Osogbo, and Ilorin, Nigeria between July and November 2019 were investigated in this study. Methodology: This was a descriptive cross-sectional study of 325 dogs with lesions suggestive of dermatophytosis, selected by simple random sampling from three veterinary clinics in Osogbo and Ilorin, purposively selected for the study due to high patronage of the veterinary hospitals by dog owners. Using conventional mycological sampling techniques, plucked hairs and skin scrapings were obtained the dogs. The samples were emulsified in 10% potassium hydroxide, examined microscopically for fungal elements and cultured using standard mycological procedures. Information on dog demographic characteristics and risk factors for dermatophytosis were collected using structured questionnaire. The association between risk factors and demographic variables with the occurrence of dermatophytoses was determined using Chi-square test (with Odds ratio and 95% confidence interval) and p value < 0.05 was considered statistically significant. Results: Positive cultures for dermatophytes were obtained from samples of 48 (14.8%) dogs with M. canis 37.5% (18/48), M. gypseum 27.0% (13/48) and T. mentagrophytes 8.3% (4/48). Other fungi identified were Aspergillus flavus 12.5% (6/48) and Malassezia canis 12.5% (6/48). The age distribution of positive dogs were < 1 year (50.0%, n=24), 1-3 years (29.2%, n=14) and > 3 years (20.8%, n=10), while the risk factors associated with dermatophytosis included sex of dogs (p=0.0428), history of dermatophytosis (p<0.0001), clinical presentation (p<0.0001) and lesion type, especially kerion and pustular lesions (p=0.0297). Conclusion: These findings established the occurrence of dermatophytosis in dogs kept for companionship (i. e., pets), security and breeding purposes in the two States in Nigeria. Our findings underscore the need for routine mycological investigations in dogs to facilitate early detection of cases and prompt institution of treatment interventions, thereby preventing zoonotic transmission of dermatophytes to their owners, handlers and veterinarians.
