[Frequency of bacteriuria in the aged (author's transl)]

1125 inhabitants of 2 homes for aged people were tested for bacteriuria by dip slides. Increasing of age did not lead to higher frequency of bacteriuria, neither in women (n = 869), nor in men (n = 256). The persons were divided in the 4 decades of being 61--70, 71--80, 81--90, and 91--99 years old. The corresponding rates of bacteriuria (greater than or equal to 10(5) germs/ml) were 14.0, 15.0, 12.4, and 9.1%, respectively. The rate of reproducibility was 75.4%, indicating still smaller values in reality. The discrepancies to the much higher values reported in the literature may depend on the people tested: "normal persons" instead of hospital patients or patients' specimens having been sent to a microbiological laboratory.
