Short description

Methicillin resistance refers to the ability of certain bacteria to resist methicillin and other related beta-lactam antibiotics.

Detailed description

Methicillin is a beta-lactam antibiotic. In cases of methicillin resistance, the target structures of the antibiotics are usually altered in such a way that many beta-lactam antibiotics can no longer be effective.
Methicillin-resistant Staphylococcus aureus (MRSA) is of particular medical significance. Infections caused by MRSA can be more difficult to treat because many beta-lactam antibiotics commonly used against S. aureus are ineffective. However, other suitable antibiotics are available for treatment.
