Strains Identification and Drug Allergy in Candida Infections An Analysis of 83 Inpatients

Objective To identify the strains of Candida and its drug resistance in the infected inpatients.Methods Strains identification and drug sensitivity tests were performed with API ATB fungus system.Results Of the 83 inpatients infected by Candida, the detectable rates of C . albicans, C. Tropicalis, C . Krusei an C . glabrate were 50.60%,26.51%,9.64%,and 7.23% respectively, the others' being under 5%. Among 6 antifungal agents , the highest drug-resistant rate fell on Azoles antifungal agents (8.43-18.07%) and the lowest rates on 5-fluorocystine,amphotericine B and nystatine (all in 1.20%) .Conclusions Clinical physicians who treat fungal infections should initially carry out bacterial culture and drug sensitive tests so as to take an appropriate care and prevent hospital-acquired infections.
