title: Evaluation of clinicomycological aspects of onychomycosis.
abstract: BACKGROUND
  Incidence of onychomycosis has increased tremendously in recent times. Relatively little work has been done on this problem in our country. Research in past has been concentrated mainly on superficial mycoses of the skin.
  
  
  OBJECTIVE
  It is a well-established fact that geographical distribution of the fungi may change from time to time; hence, this study was planned to analyze clinical, epidemiological, and mycological features of onychomycosis.
  
  
  METHODS
  Sixty patients clinically suspected and microscopically proven to have onychomycosis were taken up for the study. Nail samples, collected by scraping in 30 patients and by using a dental drill in the rest, were examined microscopically and cultured for fungus.
  
  
  CONCLUSIONS
  Forty-five fungal isolates were obtained from 60 patients. Trichophyton rubrum was the commonest fungus isolated (46.67%). Trichophyton mentagrophytes and Candida albicans accounted for 20% and 15.56% isolates, respectively. Two cases showed mixed growth of Trichophyton rubrum and Aspergillus niger in one and Trichophyton rubrum and Aspergillus fumigatus in the other. Isolation rate was higher by drilling compared to scraping, the rates being 83.33% and 66.67%, respectively. Superficial mycotic infections were present in 27 patients (45%).
