Why is Staphylococcus Aureus resistant to antibiotics?

S aureus is not especially prone to developing antibiotic resistance. Gram-negatives in general (eg E coli, Klebsiella) and Gram-negative non-fermenters in particular (Pseudomonas, Acinetobacter) develop resistance much more readily, often during a single course of treatment. read more

Over time, S. aureus has built resistance to this type of antibiotic. This is attributed to the mecA gene, which is actually transferred from different bacteria and can be traced back to Staphylococcus sciuri [9]. read more

Methicillin-resistant Staphylococcus aureus, known as MRSA, is a type of Staphylococcus aureus that is resistant to the antibiotic methicillin and other drugs in the same class, including penicillin, amoxicillin, and oxacillin. read more
