Med., 110: , Organisms Encountered in Urinary Tract Infections in the Various Groups of Patients and Antibiotic Sensitivities Takao NAGAI Central Clinical Laboratory, Kyoto University Hospital, Kyoto 606, Japan Urinary tract infections (UTI) have been investigated in 1082 patients (422 males and 660 females) of all ages with bacterial counts above 100,000 organisms per ml in urine. University of Kyoto Hospital between March, 1975 and February, The patients were seen at The organisms isolated from urine containing more than 100,000 bacteria per ml were surveyed after quantitative bacterial culture from mid-stream urine. The most frequently isolated bacteria in the patients overall were Escherischia coli (28%), Proteus spp. (15%), Pseudomonas aeruginosa (13%), and Klebsiella spp (12%). In male patients, Proteus spp. (20%) were most frequent, followed by E. coli (17%), Ps. aeruginosa (15%), Klebsiella spp. (13%), and enterococcus (13%). In female patients, E. coli (40%) was most frequent, followed by Proteus spp.(12%), Klebsiella spp. (11%), enterococcus (11%), and Ps. aeruginosa (10%). E. coli was the predominant isolate in females, both adults and children, being present in approximately 40% to 60% of positive cultures. In male patients, no isolate was predominant; the percentage of E. coli isolates was lower, and those of Proteus spp., Klebsiella spp., Ps. aeruginosa, and enterococcus werehigher than in females. In UTI in patient without underlying diseases, E. coli was the predominant isolate, being present in 40% of the positive cultures, while in patients with malignancy, the most frequent isolate was Ps. aeruginosa (20%), followed by E. coli (18%), enterococcus (18%) and Proteus spp (13%). And in UTI in patients with nephrolithiasis, Proteus spp. (25%) was the most frequent isolate, followed by E. coli (20%), Staphylococcus spp. (10%), Klebsiella spp. (10%), Enterobacter (10%), and Ps. aeruginosa (9%). spp.
