“…Consequently, fungi once considered to be nonpathogenic became pathogenic and the expansion of geographic barrier by certain pathogens is observed in the past decades (4). Majority of the clinically relevant fungi are considered as zoonotic (5).…”

The past few decades have witnessed an overwhelming increase in the incidence of fungal infections, particularly in immunocompromised individuals. Consequently, zoonotic diseases, especially through rodents constitute a prominent group among the emerging diseases. Rodents are commensal to man and related health risks are common. Water rats (Rattus norvegicus) are typical to Vembanadu-Kol wetland agroecosystems, where they can act as a good carrier nexus for pathogens. The present study evaluates the carrier status of water rats with respect to fungal pathogens. A total of fifty two fungi covering eighteen families were isolated. Among the isolates, eight were dermaptophytes and Chrysosporium sp. (89.18%) was the frequent isolate. The source-wise analyses showed an increased isolation from ventral hair (67 isolates).Water rats of Vembanadu-Kol wetland agroecosystem are potent carrier of dermaptophytes and other opportunistic fungi, and strong carrier paths are existing too.

“…Both these cultures were reported from soils of Orissa by Roy et al, 32 and from Kerala by Deshmukh. 33 Gymnascella dankaliensis was also reported from caves around Mumbai, India. 14 Chrysosporium queenslandicum (6.0%) was the next dominating species of Chrysosporium after C. indicum followed by C. zonatum (5.0%).…”

The parks of Mumbai are frequently visited by local residents every morning and evening. However, there are no reports on the occurrence of keratinophilic fungi in these areas. The purpose of this research was to study the occurrence of keratinophilic fungi in the public parks of Mumbai. One hundred soil samples were collected from five public parks: Kamla Nehru Park, Powai Garden, CD Deshmukh Garden, Five Gardens and Chota Kashmir. Keratinophilic fungi were isolated by the hair baiting technique using human hair as keratin bait. The cultures were identified using macroand micro-morphological features. Identification was also confirmed by the BLAST search of sequences of the ITS1-5.8S-ITS2 rDNA region against the NCBI/Genbank data and compared with deposited sequences. The ability of these fungi to use human hair was also evaluated by release of protein in liquid media. A total of 75 strains of keratinophilic fungi were recovered from 100 (75.0%) soil samples. The isolated fungi were composed of eleven species of eight genera: Arthrographis kalrae, Auxarthron conjugatum, Chrysosporium indicum, C. queenslandicum, C. zonatum, Gymnascella dankaliensis, G. hyalinospora, Microsporum gypseum (15.0%), Myriodontium keratinophilum, Trichophyton mentagrophytes and Uncinocarpus reesii. These fungi can release 148.8-307.6 μg/mL protein in liquid media when grown on human hair in shake flask culture and also decompose 16.2-38.6% of human hair after four weeks of incubation. Our study indicates that keratinophilic fungi are to be found in the soils of various public parks in Mumbai and that human hair can be a source of pathogenic fungi.

“…Superficial fungal infections are common skin diseases, affecting millions of people worldwide [1]. Cutaneous and subcutaneous fungal infections can be caused by dermatophytes, yeasts and non-dermatophytes molds, although dermatophytes cause most of the cutaneous fungal infections.…”

A mycological study was undertaken to determine the prevalence and incidence of superficial mycotic infections in Surguja, Chhattisgarh. Out of 187 cases 64 cases (45.3%) were infected with dermatophytes. Among them the commonest etiological agent encountered was Trichophyton rubrum (28.1%) followed by Trichophyton mentagrophytes (9.3%), Trichophyton tonsurans (4.7%) and Trichophyton violaceum (3.1%). Other most frequently isolated non-dermatophytes were Candida albicans (34.3%) and Aspergillus species (20.3%) respectively.
