Susceptibilities of Enterococcus faecalis, Staphylococcus aureus, Citrobacter spp., Enterobacter spp., Escherichia coli, Klebsiella spp., Proteus mirabilis, Pseudomonas aeruginosa and Serratia spp. isolated from patients with urinary tract infections (UTIs) in 11 hospitals during June 1992 to May 1993 to various antimicrobial agents were compared with those in the same period of previous years according to a classification, uncomplicated UTIs, complicated UTIs without indwelling catheter, and complicated UTIs with indwelling catheter. The susceptibilities of E. faecalis isolated from uncomplicated UTIs to quinolones has decreased. As for S. aureus, Citrobacter spp., Enterobacter spp., P. mirabilis and Serratia spp., which were detected very few in 1989, 1990, 1991 and 1992, their susceptibilities were not observed an obvious change. E. coli, all strains were highly susceptibilities to latamoxef and cefozopran. And the susceptibilities of E. coli isolated from uncomplicated UTIs and complicated UTIs without indwelling catheter to minocycline has decreased in 1991, but they has been indicated a trend of recovery in 1992. The difference in according UTI's classification of the susceptibilities of Klebsiella spp. to minocycline in 1991 has not recognized in 1992. And the susceptibilities of Klebsiella spp. isolated from complicated UTIs without indwelling catheter to quinolones has decreased. The susceptibilities of P. aeruginosa isolated from complicated UTIs to quinolones has been indicated a trend of recovery. These data should be considered in clinical treatment of various urinary tract infections.
