Some staph bacteria are resistant to antibiotics. MRSA is a type of staph that is resistant to antibiotics called beta-lactams. Beta-lactam antibiotics include methicillin and other more common antibiotics such as oxacillin, penicillin and amoxicillin. While 25% to 30% of the population is colonized with staph, approximately 1% is colonized with MRSA.
Most S. aureus infections can be treated with commonly used antibiotics. However, MRSA infections are resistant to an antibiotic called meticillin and also to many other types of antibiotics. Resistance means that the germs (bacteria) are not killed by the antibiotic. MRSA has become much more common since the 1980s.
