methicillin-resistant-staphylococcus-aureus (MRSA) infection is caused by staphylococcus aureus
- MRSA is resistant to the complete beta-lactam class of antibiotics. Methicillin is a member of this class of antibiotics, along with others like the more popularly prescribed penicillin, amoxicillin, and oxacillin.
- S.aureus also causes pneumonia, mastitis, skin infections, bone infections, and inflammation of the heart's inner lining.
- S.aureus becomes resistant to antibiotics like methicillin by expressing foreign proteins named PBP (penicillin-binding proteins) resistant to its action.
- Hence methicillin-resistant-staphylococcus aureus becomes resistant to a wide range of antibiotics makes the treatment choices very limited.
- The alternatives for the treatment of MRSA are dependent upon lowering the methicillin resistance.
