Keratinophilic fungi from selected soils of Bahrain

Eighty soil samples were collected from various sites of Bahrain and screened for presence of keratinophilic fungi using hair baiting techniques for isolation. Thirty-six 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 ITS1-5.8S-ITS2 rDNA region against the NCBI/Gene bank data and compared with deposited sequences for confirmation. Eight species of five genera were isolated viz. Aphanoascus fulvuscence (8.75%), Aphanoascus punsolae (20.00%), Chrysosporium indicum (2.50%), Chrysosporium tropicum (2.50%), Chrysosporium zonatum (3.75%), Spiromastix warcupii (1.25%), Microsporum gypseum (3.75%), and Trichophyton mentagrophytes (2.50%). In conclusion, our study indicates that keratinophilic fungi do occur in the various soils of Bahrain. Moreover, the narrow diversity and low density of keratinophilic fungi in the investigated soils is expected and is emblematic to other hot arid environments.
