Abstract

419 bacterial strains in 395 specimens of urine(significant bacteriuria) were found during the period of 12 months from January 1,1979 to December 31,1979, and the following results were obtained: 1. The ratio of male to female was 1.1:1(male;210,female;185) and the most common age group was 6th decade in male and 3rd decade in female. 2. 85.4% was gram negative bacilli group,14.1 percent was Gram positive cocci group and 0.5% was fungus in 419 isolated strains the isolated organisms were E.coli(35.1%), Serratia(11.2%), Proteus(11.2%), Psuedomonas(9.8%), Streptococcus(7.2%), Staphylococcus(6.0%), Klebsiella(5.7%), alcaligencs(3.3%), Citrobacter(2.6%), Enterococcus(1.0%), fungus(0.5%), acinebacter(0.2%) and flavobacter(0.2%) . In male patient E.coli(17.4%), Serratia(14.3%), Proteus(17.0%), Psuedomonas(15.2%), Streptococcus(7.2%) were the common causative organisms and in the female patients E.coli(57.0%) was the main invader. 3. In 183 patients of urologic department, the indwelling catheter and other instrumentation was the most common cause of bacteriuria in male and the uncomplicated infection was the most common one in female./ the most common causative organism of bacteriuria in the cases of uncomplicated infection obstruction and urinary stone is E.coli but Pseudomonas, Proteus and Serratia a well as E.coli were common in indwelling catheter and instrumentation group. 4. The Gram negative bacilli were sensitive to amikacin(80.5%), colimycin(70.7%), tobramycin(64.4%), and gentamicin(56.0%) and the Gram positive cocci were sensitive to carbenicillin(76.3%) tobramycin(46.7%) amikacin(43.5%) penicillin(41.4%) TAO(40.8%) and Gentamicin(40.4%).
