Abstract: (74 Views)
Introduction: Candida species, as opportunistic fungal pathogens, can form biofilms on biotic and abiotic surfaces, leading to resistance to current antifungals used in the treatment of candidiasis. This study aimed to identify Candida species from clinical samples and to assess antifungal susceptibility patterns and biofilm-forming ability.
Objective: This study aimed to identify different Candida species from clinical samples and to assess the antifungal susceptibility patterns and biofilm formation ability.
Methods: In this study, 100 Candida isolates were obtained from various clinical samples (blood, urine, body fluids, etc.) by culturing. Antifungal susceptibility assays for Candida isolates were performed using the broth microdilution technique in accordance with the Clinical and Laboratory Standards Institute M27-A3/S4 guidelines. Biofilm formation was measured by the colorimetric microtiter method.
Results: Candida albicans (48%) was the most common Candida species identified, followed by C. glabrata (34%), C. dubliniensis (9%), C. tropicalis (5%), C. parapsilosis (1%), C. krusei (1%), and two mixed colonies were identified. The antifungal susceptibility pattern shows that Candida isolates exhibit varying susceptibilities. C. albicans was 100% susceptible to amphotericin B, whereas C. glabrata was 70.58% resistant to amphotericin B. The Candida parapsilopsis isolate was susceptible to all antifungals. According to the results, Candida isolates have a moderate ability to form biofilms.
Conclusion: Therefore, periodic monitoring of Candida species prevalence and antifungal susceptibility patterns necessitates selecting the appropriate therapeutic protocol, as well as the development of novel antifungal compounds and treatment strategies.
