Sutterella Wadsworthensis is a Gram-negative anaerobic, nonspore-forming, rod Bacteria. S. wadsworth was named in memory of Vera Sutter, the director of the Wadsworth Anaerobe Laboratory in New York for twenty years. In 2006, the Wadsworth lab was working with the bacteria Campylobacter gracilis when Sutterella wadsworthensis was discovered unexpectedly. The lab discovered a new bacterial species had been discovered when Sutterella wadsworthensis displayed different and genetic criteria than C. gracilis. S. wadsworthensis has previously been isolated from canine feces. One other Sutterella species has been isolated from the feces of a healthy male Labrador dog.

S. wadsworthensis has been isolated with patients with gastrointestinal infections. One study found patients with Crohn’s disease and ulcerative colitis (UT) to contain the bacteria after performing colonoscopies on the patients. In the same study, the bacteria was also found in a control group of patients with healthy gastrointestinal tracks. Over 95% of S. wadsworthensis are susceptible to amoxicillin. S. wadsworthensis has been found in the intestinal tracks of humans and canines.
