Two microorganisms account for the majority of cases of uncomplicated UTI and pyelonephritis. Approximately 80% of acute uncomplicated UTIs are caused by E. coli. Uropathogenic E. coli clones cause the majority of uncomplicated infections and consist of only a few serogroups. Staphylococcus saprophyticus accounts for 5–15% of uncomplicated UTIs, and most infections with S. saprophyticus occur in young women in the spring and summer. 10 Enterococcus and a variety of other primarily Gram-negative aerobes account for the other 5–10% of UTIs: Proteus mirabilis, Klebsiella species, and Pseudomonas species. 4 More than 95% of UTIs are caused by a single bacterial species. Complicated UTIs are defined as those occurring in a functionally, metabolically, or anatomically abnormal urinary tract or caused by bacteria resistant to antibiotics. Basically, complicated UTIs occur in anyone who is not young, healthy, and non-gravid. In complicated UTIs, E. coli is recovered in only approximately one-third of cases (34.5%);
