Abstract

An epidemiological investigation for Methicillin-resistant Staphylococus aureus (MRSA) was performed at 21 medical institutes in Kinki area by the questionnaire from Kinki Infection Working Group in 1995.<BR>The most frequent specimen for MRSA was pus (25.3%) from out-patients and sputum (34.4%) from in-patients, respectively. As compared to the investigation of the MRSA Forum in 1992 and 1993, MRSA increased over 20%, and furthermore 57.8% was MRSA out of S. aureus under this study. It demonstrated that drug-resistance was accelerated for a few years. Polymicrobial infection, especially with more than 3 pathogens, increased significantly compared with the results of the MRSA Forum (p < 0.01). It was suggested that compromized host increased and therapy turned to be more difficult. Simultaneous pathogens detected with MRSA were Candida species, Pseudomonas aeruginosa and Enterococcus faecalis.<BR>In terms of chemosusceptibility, VCM (99.9%), ST (99.4%) and ABK (99.3%) were still determined to be higlhy sensitivity against MRSA.
