Three hundred ten bacterias isolated in significant numbers from the 276 specimens of urine during the period January 1, 1974 through December 31. 1974, were evaluated and the following results were obtained. 1. Of a total of 310 bacterial strains isolated by culture of the urine, 72.9% gram-negative and 27.1% were gram-positive. Isolated organisms include E. coli(28.1%), Klebsiella(16.1%), Streptococcus (13.1%), Staphylococcus (11.2%). Postcolon bacilli (8.1%), Enteaococcus and Pseudomonas (2.3%. each other) in order of frequency. 2. In 34 cases of acute and chronic pyelonephritis, 31 were female and only 3 were male patients. Most frequent causative organism in pyelonephritis was E. coli (61.9%) Klebsiella infection was the second most common infection in urinary tract infection (16.1%). 3. The gram-negative bacilli were relatively susceptible to Gentamicin in a range of 52.2 to 88.5% and to Kanamycin (14.3~82.7%). Penicillin G, Tetracycline and Ampicillin had nearly no effectiveness to gram-negative bacilli in this experiment.
