Staphylococcus aureus carrying PVL gene remain major health problem associated with highly virulent infections. Characterization of such gene is important to know the impact and the functional significance of nucleotide variations. PCR and standard sequencing were performed for twelve Sudanese strains from different sources. Protein structures prediction, modeling and physiochemical analysis were done to analyze genetic variation in PVL. Single nucleotide polymorphism at position ۶۱۰ (A / G) of lukS-PV was detected in all tested isolates resulted in nonsynonymous mutation in the amino acid sequence at position ۲۰۴ (N / D). Using molecular and bioinformatics tools the detected novel mutation in lukS-PV may have a diagnostic functional significance.
