Answer to Case 47

Answer: Strongyloides stercoralis
This was a challenging case. The way I would approach identification is as follows. First, you want to know what general category you would place this worm; for example, is it a cestode, nematode, or trematode. You can tell from the video that it's a nematode (round worm). Next, I would formulate a differential diagnosis based on it's size and location (small bowel). This would place Strongyloides at the top of your list, although you would want to do a permanent mount of the worm to confirm it's identity.
