Bacteriological Study of Urinary Tract Infections / 대한비뇨기과학회지

ABSTRACT

Urine specimens were obtained from one hundred and thirty nine patients in-out-patient and in-patient service of B.N.U.H., Dept. of Urology, with the presumptive diagnosis of urinary tract infections or indwelling catheter. These specimens were processed by Triphenyltetrazolium Chloride test, quantitative test and identification of the organisms. The results were as follows 1. Triphenyltetrazolium Chloride test was an easily performable and a fairmely accurate method for screening of urinary tract infections. 2. The urine specimens showed false negative reactions to triphenyltetrazoium Chloride in some cases with moderate (10(4) to 10(6) bacteria per milliliter) growth of bacteria or in the antibiotics used patients. 3. The incidence of urinary tract infections with gram negative bacilli are ninety-two percent. In their series, incidence of E. coli decreased and that of other gram negative bacilli increased such as Enterobacter, Proteus and Serratia, etc. This shift in the pathogen spectrum occurs mostly in the patients of complicated or lower urinary tract infections, in-patients, antibiotics used patients and the patients with indwelling catheter.
