Abstract: (4931 Views)
Background: Candida species are opportunistic yeasts that are capable of causing different infections and diseases among immunocompromised patients. Since Candida infections are major causes and frequent of septicemia in Neonatal Intensive Care Units (NICU), and they are associated with high morbidity and mortality rates, so obtaining adequate treatment seems necessary. Low birth weight preterm infants are especially vulnerable to these devastating infections. The aim of this study was to evaluate the drug susceptibility of Candida species colonized on the skin and mucous membrane of neonates to fluconazole, amphotericin B and caspofungin.
Methods: This study was carried out in the laboratory of medical mycology and serology, School of Public Health, Tehran University of Medical Sciences for the period of 7 months from June 2016 to December 2016. In this descriptive cross-sectional study, 23 isolates of Candida species including Candida parapsilosis, Candida albicans, Candida tropicalis, Candida guilliermondii and Candida krusei were studied. These under study isolates were previously isolated from skin and mucous membranes of neonates in NICU of Imam Khomeini Hospital and Children's Medical Center were identified by PCR-RFLP (Polymerase chain reaction-restriction fragment length polymorphism). Evaluation of antifungal drug susceptibility including fluconazole, amphotericin B and caspofungin was carried out. Antifungal susceptibility test was done according to the standard protocol Clinical and Laboratory Standards Institute (CLSI M27-A3) that is specific to the yeast fungi. Statistical analysis was done by using T-test in SPSS version 22 (IBM, Armonk, NY, USA) and P<0.05 was considered statistically significant.

| Results: In this study, C. parapsilosis, C. albicans and C. tropicalis had the most sensitivity to fluconazole. Clinical Isolates of C. guilliermondii were also sensitive to fluconazole, but in C. krusei sensitivity was dose-dependent. All isolated species were sensitive to amphotericin B and caspofungin. |
Conclusion: According to the results, all isolated Candida species were more sensitive to amphotericin B and caspofungin than other antifungal drugs. In final conclusion, Finally, it is emphasized that antifungal susceptibility testing is necessary to prevent treatment failure or recurrence of disease.
