“…Others, such as A. fulvescens, M. gypseum, Trichosporon beigelii, T. ajelloi, Sporothrix schenckii, Scopulariopsis brevicaulis, Geotrichum candidum and Pseudoallescheria boydii, can be classified as etiological agents of opportunistic mycoses. As some investigators concluded (Mercantini et al, 1980;Garg et al, 1985), due to the abundance of keratin particles and fungal pathogens of human and animal origin in densely populated areas, the probability of fungal infection in such environments is certainly higher. This probability increases in the vicinity of fungal pathogen producers and emiters, for example polluted waters or sewage sludge (Bertoldi, 1981;Ulfig, 1990).…”

Abstract. Sediments from 8 river mouths of the Catalonian coast (Spain) were examined for keratinolytic fungi. Out of 1250 river and marine samples examined, 499 (39.9%) were positive for these fungi. Aphanoascus fulvescens (anamorph + teleomorph), Chrysosporium keratinophilum, Ch. tropicum, Ch. an. of Arthroderma curreyi, Ch. pannieola, Ch. europae and Ch. indicum were the predominant species in the sediments. River samples were rich in keratinolytic fungi, whereas in marine beach sediments they occurred sporadically. The results of a preliminary experiment demonstrated that, marine water exerted a dramatical impact on river keratinolytic fungi causing their total or near-total elimination. The qualitative and quantitative compositions of fiver keratinolytic mycoflora depended on the degree of water contamination with sewage and on natural factors (mainly temperature). The keratinolytic mycoflora of two rivers was possibly altered dramatically by water contaminants, including poisons of industrial origin, and marine salinity. The problem of public health risk resulting from the distribution of keratinolytic fungi within the highly-frequented recreational waters is discussed.

“…The survey on dermatophytes and other keratinophilic fungi in the soil of parks and gardens in large towns is very interesting because of the relationship between the number of people living in the area and the presence of such fungi in the soil (19). Keratinophilic fungi play an important role in the natural degradation of keratinized residues of the soil (20,21).…”

Background: Keratinophilic fungi are a group of fungi that colonize in various keratinous substrates and degrade them to the components with low molecular weight. This study was conducted to determine the prevalence of keratinophilic fungi and aerobic Actinomycetes in soil of city parks in Gorgan. Objectives: In this study, we surveyed the city park soils of Gorgan (a northern province of Iran) to determine the identities and diversity of soil aerobic Actinomycetes, keratinophilic and non-keratinophilic fungi. Materials and Methods: A total of 244 soil samples were collected from 22 different parks of Gorgan, North of Iran. The samples were collected from the superficial layer with depth not exceeding than 0-10 cm in sterile polyethylene bags. We used hair bait technique for isolation keratinophilic fungi. The colonies identified by macroscopic and microscopic characterization after slide culturing. Actinomycetes were isolated by antibiotic dilution methods and detected by using physiological tests such as Lysozyme, Casein, Xanthine, Hypoxanthine, Gelatin, Urea Broth, and modified acid-fast stain. Results: Totally, 75 isolates of aerobic Actinomycetes were detected that Actinomadura madurae and Nocardia asteroides were the most prevalent strains, with 14.66 and 28% prevalence respectively. Microsporum gypseum was more frequent than other keratinophilic fungi (22.96%) and Aspergillus spp. was the most species of saprophyte fungi (15.92%). Conclusions: This study showed that the collected soil from studied areas was rich of keratinophilic fungi and Actinomycetes, therefore hygiene protocol should be taken to prevent the spread of pathogenic and saprophytes fungi in the environment of susceptible person.

“…In nature, they exist as self sufficient saprophytes as long as environmental conditions are favourable but they may become parasitic by accident and then pathogenic. Soils rich in keratinous material are found to be most conducive for the growth and occurrence of keratinophilic fungi (Otcenasek 1978; Mercantini et al 1980). But occurrence of keratinophilic fungi also depends upon various genomic and climatic factors such as organic matter, soil humidity, pH, temperature, soil texture, depth of soil profile and other microorganisms (Srivastava et al 1990).…”

Myco-keratinophilic species have a predilection for different keratinous substrates but show variability in their affinity towards them. Keeping this in view, a survey was conducted in the Khardung and Khardung La soils of Ladakh (India) and 28 myco-keratinophilic species belonging to 15 fungal genera (Sarocladium, Aspergillus, Beauveria, Chrysosporium, Cladosporium, Alternaria, Epicoccum, Fusarium, Gibberella, Clonostachys, Paecilomyces, Purpureocillium, Metarhizium, Penicillium and Sagenomella) were isolated by using keratin bait technique. These isolated species were tested for their preferential utilization ability and colonization on different baits by morphological assessment. Different types of keratin baits used were feathers, human hair, human nails and wool. Overall assessment revealed that feathers were colonized and utilized by all the species (100 %), followed in decreasing order by nails (89.29 %), hair (85.71 %) and sheep wool (67.86 %). So, it is concluded that feather baiting technique, could be more useful in trapping keratinophilic fungi than the hair baiting technique which is till date regarded as the best method for the isolation of mycokeratinophiles. On the basis of succession on keratinous baits, the recovered keratinophilic species were also categorized into four categories: early successional species (pioneer colonizers), late successional species (final colonizers), persistent species and no-pattern species.
