Abstract

The statistics and drug sensitivity tests of bacterial florae isolated from the urinary tract in 1983 and 1984 were reviewed. Of the 2, 222 strains isolated from outpatients, 593 (26.7%) were gram positive cocci, 21.4% were E. coli, 11.3% were Enterococcus, 10.4% were Proteus sp., 10.0% were P. aeruginosa, 5.6% were Alcaligenes sp., 4.2% were S. epidermidis and the rest were others. Of the 507 strains isolated from hospitalized patients, 107 (33.5%) were gram positive cocci, 20.3% were Enterococcus, 16.2% were P. aeruginosa, 9.1% were E. coli, 7.7% were Enterobacter sp. 7.5% were S. epidermidis, 4.9% were Proteus sp., S. marcescence and the rest were others. The percentage of E. coli, K. pneumoniae and S. epidermidis detected in the isolates from the outpatients and that of K. pneumoniae, Proteus sp. and S. epidermidis detected from the inpatients were lower than in previous reports. The percentage of P. aeruginosa and Enterococcus detected in the isolates from both groups of patients were higher than in previous reports. The major isolates (9 species) from the outpatients were more susceptible to the antimicrobial agents tested than those from the inpatients. The susceptibility of gentamicin, tetracycline and nalidixic acid to the major isolates was lower than in previous reports. During the past 2 years, we have been routinely using on inpatients the so-called new generation cefem antibiotics to treat urinary tract infections. This might be why the number of isolates of Enterococcus has increased especially in the isolates from inpatients.
