Diagnosis of Oral in Patients under 12 Years: as a Marker of Molecular Characterization of .

has been found as the most abundant pathogenic yeast species under the group Candida-non-albicans. Despite this, it is taxonomically related to and has many of its pathogenic characteristics. Infection with is closely associated with many virulence factors encoded by multiple virulence genes. This study aims to diagnose based on the presence of and to detect many virulence genes. isolates were collected from oral candidiasis patients. Children infected with oral thrush ranging in age from infants to 12 years old provided 150 samples. (66.68 %), (13.21 %), (9.43 %), (7.55 %), and were isolated as types, according to the findings of the present study (2.83%). The presence of the gene was confirmed in the isolates. All isolates were positive for and , while some were positive for (78.5%) and genes (71.4%). Using sequences and phylogenetic trees, it was determined that there was negligible genetic variation between local isolates and global strains. These virulence factor genes play a crucial role in developing infections.
