Review of Antibiotic Resistance in Staphylococcus aureus

Abstract

Staphylococcus aureus is the most common cause of infections. The response to the drug penicillin was short lived. Methicillin was introduced against penicillin resistant Staphylococcus aureus. However, the bacteria soon became resistant to methicillin also. The percentage of Methicillin-Resistant Staphylococcus aureus MRSA has been increasing globally and varies from hospital to hospital. It is associated with hospital related infections. There is also a community associated MRSA. This first started with skin infections, but was later associated with invasive infections. MRSA is detected by conventional antibiotic susceptibility testing, and also through detection of Mec A gene by PCR methods. Rapid screening methods are available now-a-days. Routine screening by rapid methods of all patients in the hospital is cost prohibitive. Patients can be isolated and strict protocols followed in containment of MRSA in a hospital environment.
