Abstract:
OBJECTIVE To investigate the relevant factors and drug sensitivity of Candida in nosocomial infection from a class A comprehensive hospital in Hangzhou in order to prevent and control nosocomial infection.METHODS We collected and identified clinic samples from inpatients during from Jan 2004 to Dec 2006 and drug resistance test was performed for Candida strains.The CHROMagar candida color medium and the Analytic Products Inc(API)20CAUX identification system were used to isolate and identify Candida strains from inpatients.The Etest was used to study the antifungal sensitivity.The data were analyzed by WHONET-5 software and were determined by the Clinical and Laboratory Standard Institute(CLSI)method.RESULTS Totally 264 strains of Candida were detected in the three years.The detection ratio in each year was 78 strains(29.5%),87 strains(32.9%),and 99 strains(37.5%),respectively.The C.albicans was the most commonly isolated species(65.5%)and then was C.tropicalis(15.1%)in all Candida species.The detection ratio was the highest in sputum samples(108 strains,40.9%)and the patients with respiratory tract infection(58 strains,22%).The results of antifungal drug sensitivity test showed that Candida were the most susceptive to amphotericin B,followed by fluconazole.The results of change showed that Candida remained stable susceptive to amphotericin B,but susceptive ratio to fluconazole was descent in the three years.CONCLUSIONS Candida in nosocomial infection are an increasing tendency and C.albicans is the commonest.Sensitivity of Candida to various antifungal drugs is different and there is a developing change in susceptive ratio to antifungal drugs.Strengthening supervising relevant factors and improving the immunity of organism are the main measures to prevent Candida in nosocomial infection.Antifungal drug should be used reasonably based on drug sensitive test.
