The term foot intertrigo covers diverse disorders with different clinical manifestations. It may present as a chronic erythematous desquamative eruption or as a more acute exudative, macerated, inflammatory eruption. Associated symptoms may range in severity and may be disabling in some cases. The etiology is variable, and a differential diagnosis based on clinical grounds is difficult because the initial phase commonly presents as an infection such as interdigital tinea pedis, candidiasis, or bacterial intertrigo. The present study was planned in the Department of Microbiology, Nalanda Medical College and Hospital, Patna, Bihar from March 2018 to November 2018. Total 50 Samples were collected from the patients with clinical suspicion of intertrigo of foot. Detailed histories such as age, sex, demographic and socioeconomic status of the patients were collected prior to sample collection. The data generated from the present study suggest that Candida albicans is the most common agents of intertrigo of foot. The diagnosis cannot only be based on the clinical aspect of the lesions. The place of mycological examination is very important in confirming the diagnosis, identifying the fungal agent and guiding the treatment. By characterizing the spectrum of pathogens usually involved, the results of this study could contribute to improve the management of intertrigo.
