[Infections with drug resistant bacteria and their treatment methods--MRSA infections]

MRSA infection is difficult to treat because of the pathogenecity of causative strains and their resistance to many kinds of antibiotics not all strains of MRSA are pathogenic agents and indications for antibiotic use should be determined strictly. Although several antibiotics show bactericidal activity against MRSA, they are not effective in all patients infected with MRSA. We should select the best drug according to the characteristics of the respective drugs in each patient and search for a better regimen to treat severely infected cases.
