Abstract

BACKGROUND:

To determine the distribution of species of Candida and the risk factors associated with candidemia in Indian population for which we conducted a retrospective study for 5 years in a tertiary care centre of North India.

MATERIALS AND METHODS:

Blood samples from 7,297 patients aged from 3 days to 85 years, suspected with candidemia, were collected and tested for Candida. The susceptibility patterns toward fluconazole for the year 2005 isolates were tested by micro-dilution assay as described in the CLSI (M27A-2 method).

RESULTS:

Most of the episodes have been caused by species other than C. albicans. Non-albicans candidemia was 79%-80% in both female and male populations. The most frequent species isolated from 275 patients in 5 years (January 2001-December 2005) was C. tropicalis (35.3%), followed by C. albicans (21.5%), C. parapsilosis (20%), C. glabrata (17.5%), C. krusei (3.3%), C. haemulonii (1.5%), and C. guilliermondii (1%). C. parapsilosis was the predominant in the fifth year of the study (2004-2005). Dose-dependent susceptibility to fluconazole was observed in 5% (n = 3) of the strains. Antifungal resistance was found in 11.7% (n = 7), which includes only C. glabrata.

CONCLUSION:

These results were comparable to those derived from other regions of India. C. tropicalis has been reported as the predominant species involved in the cases of candidemia. But in 2005 it has moved toward C. parapsilosis. No true antifungal resistance is reported. Further epidemiological surveillance is needed.
