Study Notes
Staphylococcus saprophyticus Characteristics
- Gram-positive, catalase-positive, coagulase-negative, and urease-positive cocci that grow in clusters
Identification and Differentiation
- Resistant to novobiocin (in contrast to Staphylococcus epidermidis, which is novobiocin-sensitive)
Habitat and Prevalence
- Normal microbiota of the female genital tract and perineum
Clinical Significance
- Second most common cause of uncomplicated urinary tract infections (UTIs) in young females, after E. coli
