Fugni Petri dishes were half filled with the soil samples and moistened with water leratinophilic baited with keratin by burying sterile human hairs in the soil.
This study indicates that the soils of Vidarbha region of Maharashtra may be significant reservoirs of certain keratinophilic fungi. The sequences of the ITS Chrysosporium state of Ctenomyces serratus and Trichophyton mentagrophytes were the smallest and the largest, respectively.
For example, Chrysosporium zonatum was reported to cause disseminated infection in a patient with chronic granulomatous disease [ 48 ].

The prevalence of these fungi in the soils of region of Vidarbha is of importance for their pathogenic potential and has been confirmed in several investigations in different parts of the world. View at Google Scholar E. 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.
Distribution of keratinophilic fungi in different types of soils of Vidarbha region of Maharashtra. Thus, these fungi may be regarded as opportunistic pathogens. The final products were analyzed by electrophoresis on 1. The samples were collected from forest land, cultivated land, road side, public keratinophikic, poultry farm, cattle farm, garbage, and lake side.
It was further isolated from various parts of India [ 2123 — 27 ]. The occurrence of dermatophytes in soil was reported for the first time keatinophilic Vanbreuseghem [ 3 ] using the hair bait technique.

The authors declare that there is no conflict of interests regarding the publication of leratinophilic paper. Sites of collection of soil samples in Vidarbha region keratinophiilic Maharashtra. Gymnoascoideus petalosporus was previously recorded from Chilka Lake soil [ 35 ], soils from Vedanthangal Water Bird Sanctuary [ 20 ], and soils of Orissa [ 33 ].
Its high percentage of distribution clearly indicates that it is well adapted to warmer condition of India [ 21 ].
Chrysosporium tropicum was next to M. The other species of dermatophytes recovered were Trichophyton mentagrophytes 2. These areas potentially have a high risk for causing cutaneous fungal infections in humans and animals and could be considered as a source of these infections.
For isolation, hair bait technique of Vanbreuseghem [ 3 ] was used. It is a cosmopolitan species and has been reported from various parts of India [ 17182728 ]. Negative controls were used in each set of reactions. View at Google Scholar R. Chrysosporium state of Ctenomyces serratus was recorded in 3. Introduction Keratinophilic fungi are an ecologically important group of fungi that decompose one of the most abundant and highly stable animal proteins on earth-keratin which they utilize as a nutrient substrate for growth.
View at Google Scholar C. View at Google Scholar J. The results of the isolations are presented in Table 2. Microsporum gypseum complex was found next to C. Chrysosporium tropicum was reported from comb lesion in two different breeds of chicken in India [ 50 ]. Since then studies on the isolation of keratinophilic fungi from soil have been investigated throughout the world [ 4 — 7 ].
Various workers have isolated Chrysosporium zonatum from Indian soil [ 3132 ]. The other species of Chrysosporium isolated were Chrysosporium evolceanui 2. Anamorphic state of Uncinocarpus queenslandicus i. Keratinophilic fungi are an ecologically important group of fungi that decompose one of the most abundant and highly stable animal proteins on earth-keratin which they utilize as a nutrient substrate for growth.
It is reported from Indian soils [ 262930 ]. Mycotic infection is reported throughout the world, and it is extremely contagious [ 2 ]. It was reported from Indian soils by Dey and Kakoti [ 22 ]. Seventy-one isolates were recovered and identified.
We also encountered Arthroderma sp.

Other species of keratinophilic fungi isolated were Gymnascella dankaliensis 1.

Bar indicates genetic distance due to sequence variation. These fungi were identified based on the various available monographs using macro- and keratinpohilic features of these cultures [ 8 — 12 ]. Human hairs from a years-old male were used.
