Which of the following is NOT listed among the most common pathogens of UTIs?

Explanation:
Most UTIs are caused by bacteria that originate in the gut and ascend into the urinary tract. Escherichia coli is by far the most common culprit, driving the majority of uncomplicated cases. Other frequent pathogens include Proteus species, which produce urease and are associated with stone formation, and Staphylococcus saprophyticus, a common cause in young sexually active women. Salmonella, on the other hand, is an enteric pathogen that typically causes gastroenteritis or bacteremia after ingestion and is not among the usual urinary tract pathogens. Therefore, Salmonella is not listed among the most common pathogens of UTIs.
