Tropheryma whipplei is a bacterium and the causative organism of Whipple's disease.[1] While T. whipplei is categorized with the Gram-positive Actinobacteria, the organism is commonly found to be Gram-negative or Gram-indeterminate when stained in the laboratory.[1] Whipple himself probably observed the organisms as rod-shaped structures with silver stain in his original case,[2] but no name was given to the organism until 1991 when the name Tropheryma whippelii was proposed after sections of the bacterial genome were sequenced.[3] The name was changed to Tropheryma whipplei in 2001 (correcting the spelling of Whipple's name) after deposition in bacterial collections.[1]
