Content: The gastrointestinal tract is the major reservoir of S. saprophyticus. In an early study, Latham et al. [ 19] noted that rectal, vaginal, and urethral colonization of S. saprophyticus was associated with UTI caused by this organism. Rupp et al. [ 18] determined that the prevalence of colonization of S. saprophyticus of the urogenital tract among healthy women was 6.9%; the most common site of colonization was the rectum (40%). The urine sediment of a patient with UTI caused by S. saprophyticus has a characteristic microscopic appearance; methods of chemical screening for bacteriuria do not always succeed in diagnosing UTI caused by S. saprophyticus. Even when such an infection occurs in the bladder, comparatively low numbers of colony-forming units (⩽10 5 cfu/mL) are found in the bladder and voided urine. The American Society of Microbiology's Manual of Clinical Microbiology [ 20] recommends a cut-off value of between 10 2 and 10 5 cfu/mL for the diagnosis of significant bacteriuria, but there is not a worldwide consensus for these values.
