Tropheryma whipplei, formerly called Tropheryma whippelii,[1] is a bacterium and the causative organism of Whipple's disease[2] and, rarely, of endocarditis.
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.[2] Whipple himself probably observed the organisms as rod-shaped structures with silver stain in his original case.[3]
History of the name[edit]
No name was given to the organism until 1991 when the name Tropheryma[4] whippelii was proposed after sections of the bacterial genome were sequenced.[5] The name was changed to Tropheryma whipplei in 2001 (correcting the spelling of Whipple's name) when the organism was deposited in bacterial collections.[2]
Pathogenesis[edit]
Genome structure[edit]
Several strains of Tropheryma whipplei have been sequenced.[6][7]
