[An epidemiological investigation for gram-positive coccus, especially PRSP, in Kinki area].

An epidemiological investigation for penicillin-resistant Streptococcus pneumonia (PRSP) was performed at 18 medical institutes in Kinki area by the questionnaire from Kinki Infection Working Group 1995. This investigation was the first report that was performed for a long term (one year) and a large area. The most frequent specimen was sputum from out-patients (50.3%) and inpatients (48.8%), and especially from spinal fluid of 3 cases were detected. Polymicrobial infection with more than 3 pathogens was 15.7%, and it was more frequent than MRSA previously investigated. Simultaneous pathogens detected with PRSP were Candida species, Haemophilus influenzae and Staphylococcus aureus. In terms of chemosusceptibility, VCM (100%), FMOX (97.9%), IPM/CS (85.9%), CEZ (93.4%) and CDTR-PI were determined to be high by sensitive. However, the sensitivity of CCL, which was one of the most common antibiotics, was only 37.7%.
