چکیده مقاله:
This study was conducted to confirm the phenotypic diagnosis of two Candida species, including Candida albicans (C. albicans) and Candida dubliniensis (C. dubliniensis). They were previously isolated in another study from cases of oral candidiasis using polymerase chain reaction and determining the nitrogenous base sequences of the ۱۸ SrRNA product duplication using the NS۱ and NS۸ primers. The sequences of the multiple bases were analyzed using the Basic Local Alignment Search Tool program (BLAST), which proved that the two diagnosed Candida strains belong to two species, including C. albicans and C. dubliniensis, respectively. Additionally, the comparison of these sequences to the data available in the National Center for Biotechnology Information (NCBI) database showed that C. albicans strains in this study were ۹۹% similar to the universal strains of C. albicans from Japan, Brazil, the United States, Germany, India, China, Pakistan, and Egypt. The C. dubliniensis strains in this study also had the highest genetic similarity rate of ۹۹% to the C. dubliniensis strains isolated from the United States, Netherlands, France, and Germany. The study strains were recorded in the GenBank database with the sequence codes MZ۵۷۴۱۳۷ and MZ۵۷۴۴۱۰.۱ for C. albicans and C. dubliniensis, respectively. The results of the ۱۸ SrRNA region’s duplication also showed variations between C. albicans and C. dubliniensis, represented by the presence of three mutations of the first type and two mutations in the second type at different sequence sites.
