A 19-year-old woman complained of fever and flank pain. Dysuria, urgency to urinate, and blood tinged urine were also noted. A urinalysis revealed many WBCs and WGC casts. A urine culture grew white, nonhemolytic colonies on blood agar. The colony count was 45,000 CFU/ml. No growth appeared on MAC. The organism was Catalase positive and slide-and tube- coagulate negative and produced a 21 mm zone of inhibition in the presence of a novobiocin disc.
