One hundred and fifty samples were collected from eleven districts of Vidarbha region of Maharashtra state and screened for the presence of keratinophilic fungi using hair baiting technique for isolation. Seventy-one isolates were recovered and identified. The cultures were identified using macro- and micromorphological features. Their identification was also confirmed by the BLAST search of sequences of the ITS1-5.8S-ITS2 rDNA region against the NCBI/Genbank data and compared with deposited sequences for identification purpose. Thirteen species of eight genera were isolated, namely,Auxarthron conjugatum(2.00%),Chrysosporium indicum(14.00%),Chrysosporium evolceanui(2.66%),Chrysosporium tropicum(4.66%),Chrysosporium zonatum(1.33%),Chrysosporiumstate ofCtenomyces serratus(3.33%),Gymnascella dankaliensis(1.33%),Gymnascella hyalinospora(0.66%),Gymnoascoideus petalosporus(0.66%),Microsporum gypseumcomplex (9.33%),Trichophyton mentagrophytes(2.00%),T. terrestre(3.33%), andUncinocarpus queenslandicus(2.00%). This study indicates that the soils of Vidarbha region of Maharashtra may be significant reservoirs of certain keratinophilic fungi.

The occurrence of keratinophilic fungi associated with feather samples from 10 bird species was investigated using Mycobiotic Agar(®) following the incubation at 25 ± 2°C for 4 weeks. A total of 225 feather samples were cultured, of which 157 (69.77%) were found to be positive. Altogether 184 fungal isolates represented by 11 species and grouped into five genera were recovered viz. Chrysosporium, Trichophyton, Arthroderma, Scopulariopsis and Sepedonium. Based on relative density values to rank species prevalence, the most common genus was Chrysosporium. Chrysosporium keratinophilum was the predominant species (54.34%) on most of the bird species, followed by Chrysosporium tropicum (17.93%). Relative densities of less than 10% were noticed with Chrysosporium merdarium (8.69%), followed by Scopulariosis spp. (7.06%). The lowest density of occurrence was depicted by Arthroderma tuberculatum (0.54%) and Sepedonium spp. (0.54%). Alexandrian parrots and chickens yielded the widest keratinophilic species diversity (6), followed by quail, duck and pigeons (5), while lovebirds showed the narrowest species diversity (1). The average number of species spectra and isolates per bird is 3.7 and 18.4, respectively. The study further showed that apparently healthy bird feathers can harbour a variety of fungi that may be considered as a source for transmitting potential pathogens of clinical importance.

Fifty-three soil samples were collected from various sites in the vicinity of Vedanthangal Water Bird Sanctuary and screened for the presence of keratinophilic fungi using the hair baiting techniques for isolation. Twenty-eight isolates were recovered and identified by recognition of their macro- and micromorphological features. Seven species related to five genera were recorded viz. Auxarthron conjugatum (1.89%), Chrysosporium fluviale (3.77%), Chrysosporium indicum (20.75%), Chrysosporium tropicum (7.55%), Chrysosporium state of Ctenomyces serratus (5.66%), Gymnoascus petalosporus (1.89%) and Microsporum gypseum complex (11.32%). The study shows that migratory birds harbour a variety of keratinophiles and may be a potential source of transfer of these fungi from one location to another.
