Isolation of dematiaceous fungi from soil of Mashhad, Neyshabur(north-east) and Isfahan(center of Iran) cities

Abstract

Dematiaceous fungi can infect patients who are immunocompetent and as well as may be related to in a wide variety of disorders.This study aimed to isolate and identify dematiaceous fungi from soil of Mashhad, Neyshabur and Isfahan cities.Of 93 strains isolated, the frequency of Ulocladium , Cladosporium , Aureobasidium and Alternaria were as 38.7%, 30.2%, 10.7% and 6.4%, respectively by microscopic examination. Also 13.9% were sterile hyphae. In this study, ulocladiumsp were the predominant fungi among all of the dematiaceous fungi. Although ulocladiumsp that formerly was identified as non-pathogenic saprophyte, have recently been reported in various diseases such as asthma, allergic rhinitis, hypersensitivity pneumonitis, chronic wounds, onychomycosis, cutaneous granulomas and keratitis
