Continued experimental study of the pathogenesis of sporadic bacteriuria in the rat. III

With reference to a previously published experimental model, the author relates continued experiments with sporadic, experimental hydronephrosis. The experimental animals were as previously, white female rats. The results confirmed the author's assertion that sporadic infection of an experimental hydronephrosis occurs under conditions where ascending infection of the urinary tract is precluded. In these experiments, age and environment of the animals did not influence sporadic infection. In experimental, intravenously induced Escherichia coli bacteremia, however, old age seemed to increase the frequency in the experimental model.
