The following were removed from the small intestine during upper endoscopy for abdominal pain. Identification? The larger of the 2 measures 1.3 cm in length. Bonus points for identification to the genus and species level.
Definitely A. duodenale. Lukus has given the definite identification, I only want to add that the smaller one is the typical male with its terminal copulating bursa on the left side of the picture.
Ancycloctoma duodenale - the twin ventral plates with 2 teeth each differentiate it from A. caninum which has ventral plates with 3 teeth each.
ReplyDeletethe large worm is likely a female and the smaller a male. 1.3 mm is pretty much the top range for adult females.
A. duodenale is more prominent in humans than A. caninum which, as the name suggests prefers to live in dogs
in addition, the scary 'vampireishness' of Ancyclostoma differentiates it from Necator which has slicing dicing twin ventral plates...
ReplyDeleteA. duodenale...Nice picture of the teeth! Lee
ReplyDeleteAgree with A. duodenale.
