Differentiated sap (4-6) gene expression of Candida albicans isolates from HIV-positive patients with oral candidiasis and commensals in healthy individuals

Gene expression of SAP 4-6 based on the detection of mRNA was observed in Candida albicans isolates from HIV-positive patients with oral candidiasis and commensal from healthy individuals. The species of C. albicans strains were selectively isolated from both sources using CHROMagar Chromogenic Media. The obtained isolates were then induced to express SAP 4-6 using SAP 4-6 gene inducer media. Analysis of gene expression was performed on a molecular basis using the RT-PCR method. Molecular analysis of gene expression showed that the isolates CH3 from HIV-positive patients with oral candidiasis could express SAP 4-6 gene, while commensal isolates from healthy people could not. Based on the results of this study, it could be concluded that, in terms of molecular detection, only isolates from HIV-positive patients (CH3) could express their SAP 4-6 gene.
