[Statistical studies on bacteria isolated from urinary tract infections(report 5)].
We examined bacteria isolated from urine of patients in our urological department from 1985 through 1987. A total of 2,566 strains were isolated from outpatients. They were 834 strains of gram-positive coccus (32.5%). E. coli (20.8%) was isolated most frequently, followed by Proteus sp. (12.6%), Enterococcus (9.6%), P. aeruginosa (6.7%), S. epidermidis (5.5%), and K. pneumoniae (3.7%) and others. A total of 784 strains were isolated from inpatients. They were 313 strains of gram-positive coccus (39.9%). Enterococcus (22.6%) was isolated most frequently, followed by P. aeruginosa (10.1%), S. marcescens (9.7%), E. coli (8.2%), S. epidermidis (7.9%), and K. pneumoniae (4.3%) and others. Gram-positive bacterium occupied a larger proportion of the total-isolates from both outpatients and inpatients, than in our previous examination. Fewer P. aeruginosa and Enterococcus were isolated from outpatients, and fewer P. aeruginosa from inpatients than previously. More S. marcescens were isolated from inpatients than previously. S. marcescens, E. cloacae, C. freundii, S. epidermidis, and S. aureus all isolated from outpatients showed a higher sensitivity to all drugs we tested than those isolated from inpatients.
