Abstract
The present study includs the isolation and identification of Keratinophilic fungi in fresh water samples collected from Tigris river in Baghdad, Iraq. Samples were collected from different districts of Baghdad (Al-Rustumia, Madina Al-Teb, Al-Azamia, Al-Kadimia, Al-Dorha and Al-Kanah). The water samples were examined for keratinophilic fungi by the plating method culturing and Hair Baiting Technique. A total number of 18 genera are recorded, in which the Tigris water indicates an impressive diversity of fungi. A variety of fungal strains were isolated from river water, out of 814 fungal colonies, Aspergillus terrus (5.5%) was the most frequent species, followed by Aspergillus niger (5.2%) then Rhizopus stolonifer (3.3%). The results revealed that the highest number of fungal species are found in water surface near the margin (75%) followed by the fungi isolated from water surface in the middle of the river (25%), whereas the number of fungi in 50 cm depth from water surface near the margin and 50 cm depth from water surface in the middle of the river is 17.10% and 12.20% species respectively. The results suggest that the Tigris river is a potential transmission route of fungi and a healthily hazard mainly for the immune depressed individual.
Highlights
Keratinophilic Fungi are widely distributed everywhere [1]
The keratinophilic fungi in river diversity is high enough for studying the fungal biodiversity; our efforts are increased for studying the potential ecological function of these fungi [3,4]
Madina Al-Teb, Al-Azamia, Al-Kadimia, Al-Dorha and Al-Kanah) from the Tigris river are selected for water sample collection and for fungal diversity analysis
Summary
Keratinophilic Fungi are widely distributed everywhere (soil, air, rivers, oceans etc) [1]. The number of swimmers who attend rivers with a view to the courtyard or to fish is in the increase due to the rising temperatures and increased living requirements, in addition to the notes with increasing injury people fungal skin and use of chemical treatments, which in turn is increasing. The keratinophilic fungi in river diversity is high enough for studying the fungal biodiversity; our efforts are increased for studying the potential ecological function of these fungi [3,4]. For the study of keratinophilic fungal species of the river, we have collected fungi from water to understand their fungal diversity [5]; in addition to studying the appearance and recurrence of fungal species in the Tigris River in Baghdad
