Significance of Salmonella typhi bacteriuria

Abstract

Bacteriuria due to Salmonella typhi usually occurs following recent typhoid fever or in chronic carrier states. Data from 18 patients with S. typhi bacteriuria, seen during 5 years, were analyzed. Fourteen patients had localized urinary tract infection due to S. typhi. Four others had bacteriuria, probably associated with typhoid fever. Localized abnormalities of the urinary tract and kidneys and also systemic diseases were found to predispose patients to S. typhi bacteriuria. Local abnormalities encountered included urolithiasis (n = 3), prostatic hypertrophy (n = 1), and tuberculosis (n = 1). One renal transplant recipient and another with lupus nephritis had S. typhi bacteriuria. One had associated strongyloidosis, and another was pregnant.
