Hospital sources of common Candida infections at the educational hospitals

Background: Fungi especially Candida species are sixth common agents among the pathogens in hospitals acquired infections. From fungal agents, yeasts the fourth prevalent agents of HAIs, second in UTI and fourth in blood stream infections. The aim of this study is determination of hospital sources for Candida infection by the identification of Candida species isolated from Urmia educational hospitals using PCR-RFLP methods. Methods: During six month, clinical samples of HAI cases transported to Medical Mycology Center, Urmia Medical School. At the mycology lab a rapid examination was performed for the detection of fungal elements, if positive result was seen, immediately, a full sampling was run from hospital indoor by using sterile swabs. All environmental samples and the culture media were transported to medical mycology lab. By using morphology and molecular (PCR-RFLP) methods identifications at the level of species for Candida and other fungi performed. Results: From total of 99 clinical samples %58 of colonies belonged to fungi. Thel positive cases included Candida %66.6, Aspergillus %31.4 and other fungi %0.085. Among Candida yeasts, Candida albicans %64, Candida glabrata %16.6, Candida krusei %13.88, Candida guilliermondi %2.77 and Candida tropicalis %2.75 were detected. Conclusion: Our findings showed that the sources of Candida contamination are the patient, personels and visitors. Against it, Aspergillus contaminations source by surroundings and indoor places.
