Staphylococcus saprophyticus
Staphylococcus saprophyticus (/stæfɪləˈkɒkəs səˈprɒfɪtɪkəs/) is a Gram-positive, coagulase-negative member of the bacteria genus Staphylococcus. It is one of the five most common causes of urinary tract infections (UTIs), particularly in young, sexually active women.
Etymology
The name Staphylococcus saprophyticus is derived from the Greek words staphyle (meaning a bunch of grapes), kokkos (meaning a berry), and saprophyticus (meaning putrefactive). This refers to the grape-like clusters in which the bacteria are often found, and their ability to survive on decaying organic material.
Characteristics
Staphylococcus saprophyticus is a facultative anaerobe, meaning it can grow in both the presence and absence of oxygen. It is also novobiocin resistant, which distinguishes it from other coagulase-negative staphylococci.
Clinical significance
Staphylococcus saprophyticus is a common cause of urinary tract infections (UTIs), particularly in young, sexually active women. It is responsible for approximately 10-20% of all UTIs. The bacteria can adhere to the cells lining the urinary tract, causing inflammation and symptoms such as pain and frequent urination.
Treatment
Treatment for UTIs caused by Staphylococcus saprophyticus typically involves antibiotics. The bacteria are usually sensitive to trimethoprim/sulfamethoxazole, ciprofloxacin, and nitrofurantoin.
