E.coli in the bladder and urine - can you catch that from the toilet that person used?

E. coli: A significant source of e. Coli is feces. Especially in women, with the short length of the urethra ; the closeness of the anus to the urethra, a urinary tract infection can be due to e. Coli infection from the person's very own e. Coli. While it is possible that e. Coli could come from another source like a toilet, it probably is not present in large enough amt or enough contact to be the source.
