Abstract
In order to determine the extent and causative agent of ringworm infections in Jaipur area, a study was done in outdoor patient Department of Skin, SMS Hospital, Jaipur. Out of 196 diagnosed cases, 148 were found to be positive by KOH examination while culture positive cases were 160. Trichophyton rubrum was the most common etiological type reported from 53 cases followed by Trichophyton mentagrophytes (23 cases). Trichophyton verrucosum, Trichophyton ferrugineum, Trichophyton concentricum, Trichophyton megninii, Microsporum canis, Microsporum audouinii, Microsporum fulvum were reported for the first time in Jaipur. Scopulariopsis sp., Paceilomyces sp. and Curvularia sp. were also reported for the first time from human skin in Jaipur. Tinea corporis was the most common clinical type reported from all age groups. Tinea cruris was the second most common clinical type, followed by tinea capitis, tinea manuum, tinea unguium, etc. These infections were observed more frequently in the age group of 21-30 (26 %), followed by 31-40 (18.8%) and 11-20 (16.3%). Males (75.5%) were more infected than females (24.5%). Key words: Dermatophytoses, ring worm, tinea infection, Trichophyton, Microsporum.

It may be noted that T. rubrum is the most predominant etiological agent reported from 53 cases (32.1%)
Summary
Infections caused by fungi in humans and animals are common throughout the world. Dermatophytoses are superficial infections of keratinised tissue caused by organism of three genera of fungi known as dermatophyton (Bhadauria et al, 2001). The dermatophytes represent more than 40 closely related species classified in three genera: Microsporum, Trichophyton and Epidermophyton. A few of these species are responsible for most human fungal infection (Wagner and Sohnle, 1995). There has been an increase in the incidence of fungal infections in developing countries. This may be the result of frequent usage of antibiotics, environmental condition, immunosuppressive drugs and various conditions, like organ transplantation, lymphomas, leukemia and human immunodeficiency virus (Petmy et al, 2004)
