[Urinary infection caused by non typhi Salmonella].
BACKGROUND
The aim of this study was to know the frequency and the clinical characteristics of urinary infection by non typhi Salmonella in our area in Spain.


METHODS
The clinical histories of patients with urinary infection by non typhi Salmonella diagnosed in the Hospital General del Guadalajara from January 1990 to July 1999 were reviewed.


RESULTS
During the period studied nine patients with urinary infection by non typhi Salmonella were diagnosed, representing 0.056% of the urinary infection diagnosed in our hospital over the same period. All the patients presented underlying disease and five were undergoing immunosuppressor treatment. Four patients presented urological disease. The most frequent serogroup was Salmonella enteritidis (7 cases). All the episodes were symptomatic. The same microorganism was isolated in stools in four patients. The evolution was favorable in five of the nine cases. Recurrence was observed in two patients and secondary bacteremia in one. Six patients required antibiotic treatment over two or more weeks. The mean length of treatment was of 2.5 weeks.


CONCLUSIONS
Urinary infection by non typhi Salmonella is predominantly observed in patients undergoing immunosuppression or with urological disease. Prolonged antibiotic treatment is recommended due to its bad evolution.
