UPEC (uropathogenic E. coli) is one of the main causes of urinary tract infections.It is part of the normal flora in the gut and can be introduced in many ways. In particular for females, the direction of wiping after defecation (wiping back to front) can lead to fecal contamination of the urogenital orifices. Anal intercourse can also introduce this bacteria into the male urethra, and in switching from anal to vaginal intercourse the male can also introduce UPEC to the female urogenital system.For more information, see the databases at the end of the article or UPEC pathogenicity.
