==Description and significance==
' ' Sutterella Wadsworthensis ' ' is a Gram-negative rod Bacteria. S. Wadsworth was named in memory of Vera Sutter, the director of the Wadsworth Anaerobe Laboratory in New York for twenty years(1). 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(1). S. wadsworthensis has previously been isolated from canine feces(2). One other Sutterella species has been isolated from the feces of a healthy male Labrador dog(3).

S. wadsworthensis is bile-resistant, asaccharolytic, nitrate-positive, urease- negative bacteria. The bacteria is recognized by its cell wall containing fatty acid patterns(1). Bacterial rod length ranges: 0.5-1 X 1-3 μm. S. wadsworthensis grows in a 2% to 6% oxygen atmosphere or under aerobic conditions(4). S. wadsworthensis is asaccharolytic and oxidase test negative.

More recent studies show that unlike Campylobacter gracilis, a bacterial species S. wadsworthensis is easily mistaken as, S. wadsworthensis is more commonly found in abdominal sources , while C. gracilis can be found in non-abdominal regions. It was also discovered that S. wadsworthensis is more likely to be found in more serious gastrointestinal infections than C. gracilis(5). 


One study conducted on the bacterial make up of the intestinal samples from children with autism and gastrointestinal dysfunction (AUT-GI) showed that Sutterella 16S rRNA gene sequences were present in 12 of the 23 children and non of the control patients(6). Whether the bacteria can be used as an indicator for AUT-GI or if it is part of the normal intestinal flora remains to be determined.

Sutterella wadsworthensis

Description and significance

Sutterella Wadsworthensis is a Gram-negative rod Bacteria. S. wadsworth was named in memory of Vera Sutter, the director of the Wadsworth Anaerobe Laboratory in New York for twenty years(1).

S. wadsworthensis has previously been isolated from canine feces(2). One other Sutterella species has been isolated from the feces of a healthy male Labrador dog(3).

S. wadsworthensis is bile-resistant, asaccharolytic, nitrate-positive, urease- negative bacteria. The bacteria is recognized by its cell wall containing fatty acid patterns(1). Bacterial rod length ranges: 0.5-1 X 1-3 μm. S. wadsworthensis grows in a 2% to 6% oxygen atmosphere or under aerobic conditions(4). S. wadsworthensis is asaccharolytic and oxidase test negative.
