Abstract
We analyzed bacterial strains from clinical specimens isolated with methicillin resistant (MRSA) and-sensitive Staphylococcus aureus (MSSA). The isolation rates of MRSA with polymicrobial infection, as well as the MSSA dose, were high in aspirated sputum (81%), urine (85%), drain (51%), pus (41%) and otorrhea (58%). Pseudomonas aeruginosa has been a major bacterial species in polymicrobial infection with MRSA. Xantomonas maltophilia and Acinetobacter calcoaceticus have also occurre frequently in aspirated sputum, Enterococcus faecalis in urine. On the other hand, E. faecalis and Corynebacterium spp. etc. were isolated from specimens such as drain and pus in addition to gram negative bacteria.
