[Comparative studies on activities of antimicrobial agents against causative organisms isolated from urinary tract infections (1990). II. Background of patients].
Clinical background was investigated on 861 bacterial strains isolated from patients with urinary tract infections (UTIs) in 10 hospitals during the period from June, 1990 to May, 1991. 1. Distribution of sex, age and infections: Among over fifties males, the complicated urinary tract infections was most frequent. Among females, the uncomplicated urinary tract infections was most frequent without a relation of age. 2. Distribution of sex, age and pathogens isolated from UTIs: In uncomplicated UTIs, Escherichia coli was most frequently isolated without a relation of age. In complicated UTIs without indwelling catheter, E. coli and Enterococcus faecalis were isolated with a frequency of 20-30%, respectively. In complicated UTIs with indwelling catheter, Pseudomonas aeruginosa were most frequently isolated, and next E. faecalis. 3. Administration of antibiotics and pathogens isolated from UTIs: In uncomplicated UTIs and complicated UTIs without indwelling catheter, pathogens, after administration of antibiotics, isolated from patients have obviously decreased. In complicated UTIs with indwelling catheter, pathogens, before and after administration of antibiotics, isolated from patients were not decreased. And the distribution of pathogens after administration of antibiotics was similar.
