Abstract:
Candida species are common fungal commensals in humans but can cause a spectrum of infections collectively known as candidiasis, ranging from superficial mucocutaneous disease to life-threatening invasive infections, particularly in immunocompromised individuals. In recent years, the epidemiology of candidemia has shifted, with non-albicans Candida (NAC) species such as C. tropicalis, C. glabrata, C. parapsilosis, and C. krusei being increasingly reported. Rapid and accurate species identification is essential, and MALDI-TOF MS has emerged as a powerful tool by generating species-specific protein spectra. This cross-sectional, hospital-based study was conducted from February to May 2025. Clinical specimens including blood, urine, CSF, pus, sputum, endotracheal aspirates, and bronchoalveolar lavage were processed using Hichrome Candida agar, MALDI-TOF MS, and the VITEK 2 Compact system. Of 400 samples analyzed, 74 (18.5%) yielded Candida isolates. The highest positivity was observed in sputum (29.72%), followed by urine and ETA (20.27% each). Candida albicans was the predominant species (62.16%), followed by C. tropicalis (29.72%). Less frequent species included C. kefyr and C. glabrata (2.7% each). Amphotericin B showed high susceptibility across species, while fluconazole resistance was notable in C. albicans (30%). MALDI-TOF MS is crucial for timely species-level identification and supports targeted antifungal therapy, especially amid rising NAC prevalence and antifungal resistance.
