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

S. pneumoniae is one of the most important pathogens in respiratory tract infections and systemic infections. The frequencies of isolating Penicillin-resistant Streptococcus pneumoniae(PRSP) has been increasing recently. The therapeutic strategy is becoming difficult. Ampicillin and amoxicillin are the choices of drugs to treat respiratory infections with intermediate strains. Panipenem may be the first choice of treatment for systemic infections. Administration of vancomycin should also be considered. Judicious use of antimicrobials is necessary to avoid the spread of multi-resistant strains. In some cases physical therapy would be recommended.
