Staphylococcus saprophyticus is a type of bacteria that is part of the Staphylococcus genus. It is commonly found in the environment and on human skin. This bacterium is known for causing urinary tract infections (UTIs), particularly in young women. It is coagulase-negative, meaning it does not produce the enzyme coagulase, which differentiates it from other more pathogenic staphylococci. Infections caused by S. saprophyticus are typically mild and can be treated effectively with antibiotics. It is important to identify this bacterium in clinical settings to ensure appropriate treatment, as it can sometimes be mistaken for other more harmful staphylococci.
