“…M. gypseum reported up to sixth testing in culture room condition and up to fifth testing in room temperature condition. M. gypseum frequently occurs wherever keratinaceous material is deposited [7][8]25]. Therefore M. gypseum appears to have more general distribution pattern in soil.…”

Dermatophytic and keratinophilic fungi are major components of soil microflora. Keratinolytic fungi occur abundantly in the superficial soil layers of landfills and their surroundings. The aim of the present investigation is to evaluate the survival period of these pathogenic and non pathogenic dermatophytes in different culture and temperature conditions. In present research survival period of four dermatophytic and three keratinophilic fungi has been carried out in unsterilized soil, sterilized soil and Sabouraud's dextroseagar medium at three different temperature conditions. These fungi were collected from soil samples and infected skin samples of tinea patients of Jaipur city. Bait testing (BT) and Direct soil sprinkling (DSS) methods were used for the testing of survival after every fourth month up to two years of the study. Result: Unsterilized soil and SDA medium were found more suitable for survival of all fungi. 11±1 ºC was found to be most suitable temperature condition for all tested fungi up to two years of studies. T. tonsurans has a longer survival period among all the test fungi. T. simii survived for short period of the time under different conditions.Frequently occurrence of these fungi in different localities of Jaipur district along with longer survival period in different climates concluded that Jaipur city potentially has a high risk for causing cutaneous fungal infections in human and animals.

Trichophyton rubrum is one of the well-known pathogenic fungi and causes dermatophytosis and cutaneous mycosis in human world widely. However, there are not an available sequence type (ST) classification methods and previous studies for T. rubrum until now. Therefore, currently, molecular biological tools using their DNA sequences are used for genotype identification and classification. In the present study, in order to characterize the genetic diversity and the phylogenetic relation of T. rubrum clinical isolates, five different housekeeping genes, such as actin (ACT), calmodulin (CAL), RNA polymerase II (RPB2), superoxide dismutase 2 (SOD2), and β-tubulin (BT2) were analyzed using by multilocus sequence typing (MLST). Also, DNA sequence analysis was performed to examine the differences between the sequences of Trichophyton strains and the identified genetic variations sequence. As a result, most of the sequences were shown to have highly matched rates in their housekeeping genes. However, genetic variations were found on three different positions of β-tubulin gene and were shown to have changed from C→G (1766), G→T (1876), and C→A (1886). To confirm the association with T. rubrum inheritance, a phylogenetic tree analysis was performed. It was classified as four clusters, but there was little significant correlation. Even so, MLST analysis is believed to be helpful for determining the genetic variations of T. rubrum in cases where there is more large-scale data accumulation. In conclusion, the present study demonstrated the first MLST analysis of T. rubrum in Korea and explored the possibility that MLST could be a useful tool for studying the epidemiology and evolution of T. rubrum through further studies.
