Content: 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. Colonization is more frequent during the summer and fall. Hovelius et al. [ 21] showed that women with S. saprophyticus colonization were more likely to have had a symptomatic UTI during the previous 12 months, to have recently had a menstrual period, and to have had sexual intercourse concurrent with vaginal candidiasis than were women without colonization. None of the women developed symptomatic UTI during the next 6 months. Further support for the existence of a rectal reservoir was the isolation of the same plasmid-identified clone from both urine and stool samples [ 22 ].
