[Bacteriology and resistance in ambulatory urinary infections].
OBJECTIVE
To discover the bacteriological profile of urinary tract infections (UTI) in our out-clinic environment and their resistance to the most common antibiotics.


METHODS
A descriptive, retrospective study.


METHODS
Ciudad Real Health Area (300,000 inhabitants).


METHODS
All the urine samples from the out-clinics referred to the microbiology lab for possible UTI in 1994 were included.


RESULTS
3,522 cultures were studied, of which 241 were contaminated (7%), 2,870 negative (81%) and 409 positive (12%). Breakdown of bacteria: E. coli (248; 60%), enterococci (38; 9%), P. mirabilis (25; 6%), K. pneumoniae (20; 5%), S. epidermidis (11;3%), S. saprophyticus (8; 2%) and 61 others (15%). We found high sensitivity in the Gram-negatives to cephuroxim and amoxicillin-clavulanic. We observed widespread resistance, especially by E. coli, to quinolones, pipemidic acid and nitrofurantoin.


CONCLUSIONS
E. coli is the micro-organism which most often causes UTI in our environment. We found enterococci were isolated more and S. saprophyticus less than in the series consulted. We found a considerable increase in resistance to some antibiotics often used in out-clinics for UTI treatment.
