Urinary tract infections associated with nontyphoidal Salmonella serogroups.
In an analysis of over 23,000 nontyphoidal strains of Salmonella submitted to the Microbial Diseases Laboratory between 1992 and 1996, two groups (C(1) and E) were significantly recovered more often from the urinary tract than stool compared to more common groups such as B and D. An analysis of >60 urine isolates from 1996 suggests that most of these represent true urinary tract infections, as opposed to colonization or fecal contamination, by virtue of being isolated in pure culture and in high concentrations (>100,000 CFU/ml).
