This review traces the early records of mycotic infections in India, and presents an update of animal mycoses reported from several parts of India. The types of mycoses covered are the dermatophytosis (ringworm) in domestic animals due to well-known species of zoophilic dermatophytes, viz. Trichophyton simii, T. mentagrophytes, T. verrucosum, Microsporum canis and M. nanum, and the geophilic dermatophyte, M. gypseum, Aspergillus spp, Cryptococcus species and other yeast like fungi, histoplasma and blastomyces. The brief clinical and demographic features of infections in different animals are described. A particularly noteworthy finding in literature search is the report of clinical infections in one dog and two cows by an anthropophilic dermatophyte, T. rubrum from Belgachia, Kolkata, West Bengal in 1954. Veterinary scientists are urged to investigate the possible occurrence of infections in animals due to other pathogenic fungi including the dimorphic ones like Histoplasma and Blastomyces.

The article presents the results of the study of the species composition of the microbiota of the skin surface of the auditory canal for otitis in dogs, in particular the results of the study of the fungal microbiota and the frequency of associations of pathogenic fungi with bacterial pathogens. Objective Investigation of the ear microbiota in dogs with otitis with the aim of identifying microbial/fungal species composition and establishing the role of yeasts in the etiology of otitis, identifying possible associations of fungi and pathogenic staphylococci. Materials and methods Experimental animals were dogs aged from 6 months to 10 years. During the period 2018-2020, 30 dogs of various breeds weighing 5-60 kg, of both genders, with otitis symptoms were examined. During the study, sampling of clinical material from affected animals, isolation of pathogen cultures on nutrient media, the study of their cultural properties and the determination of sensitivity to the corresponding drugs were carried out. As the research results showed, among the representatives of yeast fungi in the material isolated from dogs with otitis, Malassezia pachydermatis was most often isolated - 9 cases (30%). Representatives of Candida albicans were isolated in only 1 case (3.3%), so their clinical significance requires further study. These fungi could be extraneous contaminants. It should be noted that in 9 cases (30% of the number of cases of Staphylococcus aureus isolation) associations of S. aureus were observed with Malassezia pachydermatis fungi, in 6 cases (20%) associations of Staphylococcus pseudintermedius with Malassezia pachydermatis fungi were observed; in 5 cases (16.7%) – associations of S. aureus with gram-negative Proteus spp. Conclusions 1. Among representatives of yeast fungi in the material isolated from dogs with otitis, M. pachydermatis was most often isolated – 9 cases (30%). 2. Representatives of C. albicans were isolated in only 1 case (3.3%), so their clinical significance requires further study. These agents could be extraneous contaminants. 3. It should be noted that in 9 cases (30% of the number of cases of S. aureus isolation) associations with M. pachydermatis fungi were observed, in 6 cases (20%) associations of S. pseudintermedius with M. pachydermatis fungi were observed; in 5 cases (16.7%) – associations of Malassezia with gram-negative Proteus spp.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
