Abstract

Urinary tract infections (UTIs) remain a worldwide nosocomial infection problem. Geographic variations in pathogen occurrence and susceptibility profiles require monitoring to provide information to guide new (garenoxacin [BMS284756]) therapeutic options. Two thousand seven hundred-eighty UTI isolates from Europe (n = 783), Latin America (531), and North America (1,466) were tested and compared against 44 agents by reference methods in the SENTRY Antimicrobial Surveillance Program. The top seven pathogens accounted for 90% of all isolates and the rank order for all regions was: Escherichia coli (1,316; 47%), Enterococcus spp. (351; 13%), Klebsiella spp. (306; 11%), Pseudomonas aeruginosa (210; 8%), Proteus mirabilis (145; 5%), Enterobacter spp. (97; 4%), and Citrobacter spp. (78; 3%). The pathogen rank order was similar among regions except for the rarer occurrence of Enterococcus spp. (Rank #6, 4%) in Latin America. E. coli ampicillin resistance was highest in Europe and Latin America (51-55%). Ampicillin (37%), ciprofloxacin or garenoxacin (4%), and trimethoprim/sulfamethoxazole (23%) resistance remained lowest in North America. Nitrofurantoin susceptibility in E. coli was still at acceptable levels and ranged from 91 to 96% across regions. The regional ciprofloxacin-resistant rank order for P. aeruginosa by region was: Latin America (55%) > Europe (41%) > North America (29%). Vancomycin-resistant enterococci (VRE) were only detected in North America (7%). Garenoxacin possessed a 34 to 44% wider spectrum compared to ciprofloxacin against enterococci UTI isolates. Extended spectrum beta-lactamase rates for E. coli and Klebsiella spp. were 4 and 19%, respectively. These results emphasized the need to assess the often striking differences in pathogen occurrence and resistance rates among the commonly encountered UTI pathogens.
