Uncomplicated urinary tract infections in young, sexually active women are often caused by Staphylococcus saprophyticus. A key lab clue that helps confirm this organism is its resistance to novobiocin. This resistance differentiates it from other Staphylococcus species, such as Staphylococcus aureus, Staphylococcus epidermidis, and Staphylococcus lugdunensis, which are typically inhibited by novobiocin. The combination of the patient group and the novobiocin resistance pattern points to Staphylococcus saprophyticus as the most likely culprit.
