Abstract: 

From Mar 2000 to Nov 2001 the prevalence of resistance to ampicillin, sulfomethaxazol-trimetoprim, (SXT) nitrofurantoin, nalidixic acid, ciprofloxacin, cephalothin, and gentamicin in 740 gram-negative bacilli isolated from outpatients with acute urinary tract infections (UTIs) at Kashan Central Laboratory was prospectively evaluated. Eschericia coli (Ecoli) (75%) were the most common causing UTIs, followed by Klebsiella spp. (17%) and Proteus spp. (2.1%). Among them 80°% more isolates were resistance to ampicillin and 47% more isolates to SXT. Cephalothin resistance among E.coli isolates was >28%, Klebsiella spp 32.1% and Proteus spp. 40%. Overall, the rate of ciprofloxacin resistance among them was 7.8 to 18.2%. Nalidixic acid resistance among E.coli isolates was 6.5°0, Klebsiella spp 9.7% and Proteus spp 15%. Among the isolates, 15% less isolates were resistance to gentamicin. Nitrofurantoin showed the lowest resistance rates (<4.5%) with exception of the Proteus spp. (10%). The high prevalence of resistance is surprising, it may reflect the widespread use of antibiotics in Kashan continued regional, and national surveillance is warranted.
