Keratinophilic fungi isolated from hospital dust and soils of public places at Gulbarga, India

Abstract

Keratinophilic fungi were isolated from corridor dust of 11 hospitals and soils of 21 public places using a hair baiting technique. A total of 41 species belonging to 24 genera were recovered. Among the dermatophytes and related species, Microsporum gypseum was predominant, followed by Chrysosporium keratinophilum, Trichophyton mentagrophytes, M. nanum and Ch. tropicum. Other species were represented by 32 species belonging to 21 genera. Most of the species isolated are known to be agents of human and animal infection or have been isolated from human and animal lesions. The fungi observed here are discussed in relation to their global distribution.

Dermatophytes, Related Keratinophilic and Opportunistic Fungi in Indoor Dust of Houses and Hospitals

“…But these fungi were not reported from indoor hospital and house dust nor was their hair perforating ability determined. However, Vidyasagar et al [7] reported keratinophilic fungi from hospital dust and soils of public places from Gulburga, India. Kushwaha [8] reported dermatophytes and keratinophilic fungi from hospital waste collected outside.…”

Isolation of Keratinophilic Fungi and Aerobic Actinomycetes From Park Soils in Gorgan, North of Iran

“…The keratinophilic fungi and aerobic Actinomycetes are distributed worldwide (8)(9)(10)(11) which is more attracted Iranian researches in recent years (4,(12)(13)(14)(15). In this study, we surveyed city park soils of Gorgan (a northern province of Iran) for determine the identities and diversity of soil aerobic Actinomycetes, keratinophilic and non-keratinophilic fungi.…”

Onygenales (Eurotiomycetes, Ascomycota) Queratinofilicos en Suelos De Establecimientos Educacionales Urbanos Y Rurales De La v Region, Chile.

“…Urbano Rural actividad de los niños en las aulas, aportan el material queratínico necesario para mantener la presencia y diversidad de estos hongos en zonas menos antropofizadas (Otcenasek et al, 1967;Dominik et al, 1973;Van Gelderen & Elias, 1978;Marchisio, 1986;Zaror et al, 1986;Piontelli & Toro, 1987;Caretta et al, 1976Caretta et al, , 1989Mercantini et al, 1995;Armes & Hilda, 1998;Mangiaterra et al, 2000;Shadzi et al, 2002;Vidyasagar et al, 2005). Los integrantes del género Chrysosporium obtuvieron los mayores aislamientos y el mayor número de especies en ambas zonas, pero con un notable aumento de frecuencia de presencia y diversidad en la zona rural.…”

“…(Alvarez & Bracalenti 1984;Piontelli et al 1984;Armes & Hilda, 1998;Mangiaterra et al, 2000;Shadzi et al, 2002;Vidyasagar et al, 2005). Los suelos de los establecimientos educacionales y áreas circundantes, son frecuentemente fuente de substratos queratínicos aportados por animales domésticos, aves y presencia humana (estudiantes), presentan gran interés ecológico y epidemiológico (Marchisio et al, 1986;Armes & Hilda, 1998).…”
