Soil samples collected from glacier banks of Gulmarg, Khilanmarg, Sonamarg and Tangmarg of Kashmir valley, were examined for the prevalence of keratinophilic fungi and related dermatophytes. From the 72 positive samples (67.3 %), a total of seven genera with eleven species were isolated viz. Chrysosporium keratinophilum (3.7 %), Chrysosporium tropicum (5.6 %), Chrysosporium state of Ctenomyces serratus (11.2 %), Geomyces pannorum (2.8 %), Malbranchea sp. (0.9 %), Microsporum gypseum complex (20.6 %), Microsporum nanum (1.9 %), Microsporum vanbreuseghemii (0.9 %), Trichophyton ajelloi (15 %), Trichophyton terrestre (2.8 %) and Uncinocarpus reesii (1.9 %).
Keywords: Soil fungi, keratinophilic fungi, glacier bank, Kashmir Valley, India Keratinophilic fungi have been isolated from Indian soils by various investigators (Randhawa & Sandhu, 1965; Garg, 1966; Deshmukh & Agrawal, 1983; Ghosh & Bhatt, 2000). Isolates have been obtained from Gulmarg and Sonamarg in Sind or Aru in Lidar, all above 8000 feet, where the temperature hovers around 15°C and the mean temperature in July never exceeds 10°C at 10,000 to 12000 feet. Even colder sites are met with at higher altitudes. The banks of glaciers, prevalent in these regions, are used for commuting purposes by both tourists and locals and also serve as grazing sites for sheep, horses and mules. This paper reports the prevalence of keratinophilic fungi and related dermatophytes in sites located along the banks of glaciers of those regions, particularly Gulmarg, Khilanmarg, Sonamarg and Tangmarg. Materials and methods Soil samples were collected from the banks of glaciers in Gulmarg, Khilanmarg, Sonamarg and Tangmarg region of the Kashmir valley. Banks of glaciers indicate muddy soils, sandy soils, grassy areas, footpaths used by locals and include temporary sheds set up by locals for tourists. Samples were also taken from the areas where sheep, horses and mules rest on the banks of glaciers.
Superficial layers were scraped to a depth not exceeding 3-5 cm and collected in sterile polythene bags and brought to the laboratory, where they were stored at 15°C if not processed promptly. Keratinophilic fungi were isolated by the hair baiting technique of Vanbreuseghem (1952) using horse hair as keratin bait. Results and discussion Of 107 samples examined, 72 showed the presence of keratinophilic fungi (Table 1) which included 11 species in seven genera. Microsporum gypseum was the dominant species (20.6%). It is a geophilic dermatophyte, universal in soil and has been encountered in one or more countries of each continent (Ajello, 1953). It causes ringworm of the scalp and glabrous skin in human beings (Rippon, 1988). Trichophyton ajelloi was the next most frequent isolate (15 %) followed by the cosmopolitan Chrysosporium state of Ctenomyces serratus (11.2 %). Various workers (Randhawa & Sandhu, 1965; Garg, 1966; Deshmukh & Agrawal, 1983; Deshmukh et al., 2000) have reported these fungi from Indian soils. Chrysosporium indicum was absent in the present survey though it has been reported from higher altitudes (Randhawa & Sandhu, 1965; Garg, 1966 and Deshmukh & Agrawal, 1998). Regarding other dermatophytes, we encountered Microsporum nanum, M. vanbreuseghemii, and Trichophyton terrestre which were recovered from 1.9 %, 0.9 % 165

and 2.8 % of soil samples respectively. Microsporum nanum has also been reported from Indian soils (Jain et al., 1985 and Ghosh & Bhatt, 2000). It is known to cause diseases in man, dogs and pigs (Gupta et al. 1968; Garg & Muley, 1972). Microsporum vanbreuseghemii was isolated from Indian soils by Sethi et al. (1967). Trichophyton terrestre was isolated from Indian soils by various workers (Deshmukh, 1985; Verma et al., 1982 and Ramesh & Hilda, 1998-99). From our investigation the species of Chrysosporium reported are C. keratinophilum (3.7 %) and C. tropicum (5.6 %). Various species of Chrysosporium have also been reported from various parts of India (Garg, 1966; Roy et al., 1972; Deshmukh, 1985 and Ramesh & Hilda, 1998-99). Geomyces pannorum was recovered from 2.8 % samples only. It is also reported from other parts of India by Deshmukh et al. (2000) and Kaul and Sumbali (2000). Ulfig & Ulfig, (1990) reported it from bottom sediments of artificial lakes in Poland and Ulfig et al. (1998) from sediments of river mouths along the Catalonian coast, Spain. A single isolate of Malbranchea sp. was recovered from 0.9 % samples only. Its systematic position has yet to be confirmed. Uncinocarpus reesii was recovered from 1.9 % of soil samples only. Ghosh & Bhatt (2000) have also reported it from Chilka lake soils. This is the first report of the occurrence of keratinophilic fungi from glacier bank soils of India. From this study it appears that these fungi have adapted to temperatures below 10°C and even freezing temperatures in winter. The significance of the occurrence of these wellknown dermatophytes along glacier banks is not clear. Whether they are opportunistic and potential pathogens is debatable. However, reports of Gymnascella 166

hyalinospora causing pulmonary infections and Chrysosporium zonatum causing a disseminated infection that included pneumonia, pleuritis, pericarditis and osteomyelitis in a chronic granulomatous disease patient are indicative of potential pathogenicity of such organisms (Roilides et al., 1999; Iwen, et al., 2000). Chrysosporium infection in a bone marrow transplant recipient was noted as Chrysosporium which caused an invasive infection in an 18 year old woman where the infection began as a facial swelling and extended into the central nervous system (Warwick et al., 1991). These fungi may therefore be regarded as ‘opportunistic’ pathogens. Acknowledgment The author is thankful to Dr. R. K. S. Kushwaha, Christ Church College, Kanpur, India, for identification of some of the isolates.

The Howard Eggins Meeting 2001 Following a successful inaugural meeting (reported in Mycologist 15 Part 1, p 43) the Society once again held the Howard Eggins Meeting in the traditional atmosphere of the Linnean Society rooms. On 15 November 2001 Prof A.J.S.Whalley and Dr Susan Isaac chaired sessions in which seven papers were presented on a diverse range of topics. Lianne Nugent (Liverpool John Moores) described her work on endophytic ascomycete fungi as A day in the life of a sneaky fungus, which was followed by Nutthaporn Ruchikachorn (Liverpool John Moores) studying Endophytic Fungi in Thai Medicinal Plants. Cherdchai Phosri (Liverpool John Moores) gave a summary of his work on Basidiospore wall ornamentation in Pisolithus arhizus and other submissions were presented by Euan Burford (University of Dundee) on Rock-forming Fungi and Shannon Molloy (HRI Wellsbourne) on The role of sugar transporters in mushroom growth and morphogenesis.
After deliberation the judging panel decided that the winner of the Howard Eggins Award was Christiane Baschien, of the Technical University of Berlin, for her presentation entitled Phylogenetic analysis and in situ detection of freshwater fungi. [The award was later presented by Mrs Linda Eggins, at the 2001 Annual General Meeting in London]. Following past practice some light relief was included in the programme; Professor John Webster gave a liberally illustrated talk on Mechanisms of Ballistospore discharge. In addition, the winner of the Society’s Microscopy Award, given for the best paper including an element of microscopy at any meeting during the current year, was determined at this event. This award went to Amanda Wallington (University of the West of England), for her presentation on NMR Micro-imaging of Wheat grains infected by Spoilage Fungi. G Hadley 167
