- Staphylococcus saprophyticus is a Gram-positive, coagulase-negative, non-hemolytic coccus that is a common cause of uncomplicated urinary tract infections (UTIs), particularly in young sexually active females.
- S. saprophyticus is the second most common cause of community-acquired urinary tract infections, after Escherichia coli.
- In females ages 16 to 25, it causes up to 42% of all infections.
- Over 40% of all young, sexually active women contain S. saprophyticus as part of their normal genitourinary flora
The antibiotic of choice in uncomplicated S. saprophyticus UTIs is nitrofurantoin 100 mg orally twice daily for five days, or for seven days in complicated cases. Trimethoprim-sulfamethoxazole (TMP-SMX) 160 mg/800 mg by mouth twice daily for three days may be given alternatively in uncomplicated cases.
