Molecular identification of intercellular gene icaA and icaD lead to staphylococcus aureus biofilm-associated formation of nasal isolated among medical laboratory technology students in UiTM Puncak Alam / Nor Farhanah Kamal

Previous study have been done and reported that S.aureus strain clinically is type of common normal flora in any part of human body especially in nasal part. Statistically, 45% of human population is a carrier of S.aureus. However, the ability of S.aureus to produce biofilm will significantly cause...
