ABSTRACT
Objective To study the drug susceptibility,potential toxin factors,and genotypes of Candida albicans.Methods Forty-six strains of C.albicans were isolated from clinical samples of lower respiratory tract infection.The genomic DNA was amplified by PCR to determine the 25S rDNA genotypes.The drug sensitivity was investigated by disk diffusion and broth dilution respectively.Adhesiveness test and protease activity assay were performed.Results Forty-six strains were divided into A(18),B(6),and C(22) three genotypes.Most trains displayed high sensitivity to natamycin,amphotericin B,nystatin,fluorocytosine,and itraconazole.MIC results showed that there was significant difference against fluconazole and 5-fluorocytosine between A and B as well as C genotypes(P0.01).The cell adhesiveness test demonstrated that the strain adhesiveness was proportional to the protease activity(r=0.977,P
