Risk factors associated with dermatophyte- causing agents (Trichophyton rubrumand Trichophyton mentagrophytes)
Journal Title: MedPulse -International Medical Journal - Year 2017, Vol 4, Issue 2
Abstract
Background: Dermatophytosis is a common disease in tropical countries due to factors like heat and humidity. Trichophyton rubrum and Trichophyton mentagrophytes, which cause infections of skin and nails, are two of the most frequently isolated dermatophytes. Transmission may occur by direct contact or indirectly by fomites, however, overcrowding, excessive moisture or low economic status may constitute risk factors when combined with exposure to the etiologic fungi. The present study was undertaken to study the risk factors associated with two common dermatophyte-causing agents T. Rubrum and T.mentagrophytes. Material and Methods: A total of 187 patients clinically diagnosed as Tinea corporas who were fungal culture positive and treatment naive patients at first visit were included. Samples were collected and direct microscopy by KOH and culture on SDA with antibiotics were done. Results: T. rubrum was isolated from 72.7% and T. Mentagrophytes from 27.3%.Most of the patients i.e. 66 (35.3%) were in the age group of 21-30 years and were males. Housewives constituted 26.8%, a substantial percentage of patients (12.8%) were labourers and 17.1% were students. 92.5% patients had some level of education and 7.5% had not received any education. In our study 81.8% belonged to lower income group and 24.1% of patients lived in well ventilated houses. Discussion: Dermatophytosis is the commonly encountered fungal infection in developing countries like India. Overcrowding, poor hygiene, low standards of living along with high humidity environments contribute to the increased prevalence of these fungal infections.
