title: Investigation of extracellular phospholipase and proteinase activities of Candida species isolated from individuals denture wearers and genotypic distribution of Candida albicans strains.
abstract: In order to determine the relationship between the development of denture related stomatitis (DRS) and the production of phospholipase and proteinase by Candida species, 156 Candida isolates isolated from the individuals in the control group and from the individuals different denture wearers were included in this study. According to the results of the study, C. albicans strains were determined to produce high levels of phospholipase and proteinase. It was also determined that the prevalence of phospholipase and proteinase activities in C. albicans strains isolated from individuals with DRS and from the individuals without DRS was not different. In order to determine genotypic variation of 109 C. albicans strains isolated, CA-INT-L and CA-INT-R primers specific to the site of the transposable group I intron of the 25S rRNA gene (rDNA) region were used. As a result, it was considered that, there were several other virulence factors belonging to the microorganism which played a role in the development mechanisms of the infection caused by C. albicans. In addition, according to the results of microbial genotyping, it was determined that there were no C. albicans strains specifically responsible for the development of DRS.
