Abstract
Onychomycosis is a common nail infection caused by
dermatophytes, yeast or other non-dermatophyte molds and
have been known to be associated with significant physical
and psychological morbidity. This study was performed to
determine the prevalence and the etiologic agents of
onychomycosis in patients attending RIMS, Imphal,
Manipur for a period of two years (January 2010 to
December 2012). Nail samples of 347 clinically suspected
cases of onycomycosis attending dermatology OPD RIMS,
Manipur were collected and were subjected to potassium
hydroxide (KOH) mounts for direct microscopy and fungal
culture on Sabouraud’s dextrose agar (SDA). The male
female ratio of the participants was 1:1.81 (165 male and
302 female). Out of 467, 399 (85.44.%) were positive by
culture and KOH mount. Young adults in the age group of
21-30 years were commonly affected. In female patients
finger nail infection was more common than toe nail
infection. Both toe and finger nails involvement were noticed
in nine patients of which two were male and seven were
female. The most frequently isolated fungus was
dermatophytes, in 107 (40.38%) patients followed by
Aspergillus spp in 101 (38.11%) and Candida spp in
17 (6.4%). This study demonstrated that dermatophytes,
as well as moulds especially Aspergillus spp are commonly
isolated from onychomycosis patients in our region.
