EMERGENCE OF NON-ALBICANS CANDIDA & USE OF CHROMAGAR FOR SPECIATION OF CANDIDA IN A RESOURCE-LIMITED SETTING
Keywords:
Non albicans Candida, CHROMagar, Candida albicansAbstract
Objective: Candida infections, especially those caused by Non-albicans Candida (NAC) species, have become increasingly common in recent years. These species' early isolation and identification are essential for their effective management. This study aimed to evaluate the efficacy of CHROMagar for the speciation of Candida. Materials and Methods: All clinical samples received in the microbiology laboratory from April 2023 to March 2024 were processed as per microbiological criteria. The isolates that revealed Gram-positive budding yeast cells on Gram staining were further identified and speciated using CHROM agar and conventional methods. Results: A total of 749 Candida were isolated from various clinical samples. Candida albicans was the most common species isolated (46.41%), followed by C. glabrata (23.63%), C. krusei (14.15%), C. parapsilosis (9.2%), and C. tropicalis (6.5%) while sensitivity and specificity of CHROM agar was 100% for C. glabrata and C. krusei and 98.3% & 100% for C. albicans while 100% sensitivity & 94.2%,96% specificity for C. parapsilosis and C. tropicalis respectively when compared to conventional methods. Conclusion: CHROM agar's performance was nearly identical to that of conventional methods. Compared to time-consuming, technically complex, and costly conventional methods, using this medium is quick, easy to use, and economical.
