Clinical spectrum of urinary tract infections due on nontyphoidal Salmonella species.
We performed a retrospective analysis of 28 cases of bacteriuria due to nontyphoidal Salmonella (NTS). Twenty-one patients (75%) had symptoms of urinary tract infection (16, cystitis; 3, pyelonephritis; and 2, renal abscess), and 7 remained asymptomatic. In 24 cases NTS was the sole pathogen isolated from urine. Salmonella enteritidis (a Salmonella subgroup 1 serotype) was the serotype most frequently isolated (16 cases), followed by Salmonella enteritidis serotype typhimurium (5 cases). Sixteen patients (57%) were severely immunocompromised, and 14 (52%) had urologic abnormalities. Recurrence of bacteriuria occurred in four patients. It is suggested that in cases of urinary salmonellosis one must consider the existence of an occult urologic problem or severe immunosuppression.
