Content: The organism was found to belong to micrococcus subgroup 3. It was later reclassified as S. saprophyticus. Urease production is another important characteristic, and renal and ureteral stones were found to be associated with S. saprophyticus infection [ 5 ]. Laboratory diagnosis. Laboratory identification of S. saprophyticus is made on the basis of resistance to novobiocin, the absence of hemolysin and coagulase, and intense pigment production. Approximately 65% of strains are yellow, and 35% are white [ 3 ]. Testing of novobiocin susceptibility is reported to be 100% sensitive and 96% specific [ 4 ]. This provides a simple and reliable screening method to differentiate the presence of S. saprophyticus from the presence of other coagulase-negative staphylococci, but further tests are recommended for final identification. Epidemiology. S. saprophyticus is second only to E. coli as the most frequent causative organism of uncomplicated UTI in women.
