Summary:Since the introduction of quantification of bacteriuria by Kass in 1956, many studies on urinary tract infections have been reported. However, most of them was concentrated on the young and women of child bearing age. It is generally accepted that the incidence of urinary tract infection is high, and that it escapes clinical notice in a high proportion of patients, yet there have been few studies of the condition in the aged. Our study was undertaken to determine the prevalence of significant bacteriuria and to investigate the sensitivity of predominating organisms to various antibiotics in the group of patients over the age of 65. The patients were screened for the evidence of urinary white cell count and/or urinary tract symptoms. The urine specimen were taken by catheter and cultuered as soon as possible. Of the 95 specimens examined, 63 (67.4%) were found to have significant number of organisms (greater than 100, 000 per ml urine). E. coli, Proteus, Enterococcus and Klebsiella were predominate organisms found. In 38 (60.3%) specimens single species were isolated, and in the remaining 25 specimens, mixed cultures were obtained. In the drug-sensitivity patterns, E. coli was sensitive to KM, CL, AB-PC, CP, CER, NA, SM and TC in this order. Proteus was sensitive to SM, AB-PC, CP and CER. Asymptomatic bacteriuria was noted 39.7% of 63 patients.
