Staphylococcus sciuri is one species of a group of bacteria common in wildlife. In humans, Staphylococcus sciuri is an extremely rare microbe isolated from the urinary tract. A 2003 article in the Journal of Clinical Microbiology studied 32,741 urine samples and isolated only 13 samples with Staphylococcus sciuri. Of those 13 isolates, only one case of symptomatic urinary tract infection and five cases of asymptomatic bactiuria (greater than 100,000 colony forming units of the same species in a urine culture of a patient without symptoms) were established. Therefore, the study concluded that Staphyloccoccus sciuri can be a pathogen: it is an extremely rare cause of urinary tract infection and can also cause asymptomatic bactiuria. The bacteria is sensitive to Trimethoprim-Sulfamethoxazole (Septra or Bactrim).
