Answer:Trichuris trichiura (whipworm), maleAs nicely pointed out by Florida Fan, " No, this worm is not so straight. It ’s totally so convoluted like the whip of “Dr. Jones” in the movie .

Answer to Case 515
Answer:Trichuris trichiura,a.k.a. " whipworm "As noted by Florida Fan, " we can clearly see the thread-like anterior portion and an inflated posterior, giving the worm resemblance to a whip " . I always like to ask my students which end they think is anterior - they invariably (incorrectly) guess that it ' s the broader end! This gives me the opportunity to walk them through the life cycle and how the adult worms are embedded within the mucosa of the large bowel. It always seems to make more sense to them when I ask which end would be easier to thread into the wall of the bowel - the thin end or the thick end? This helps e...

Answer to Case 504
Answer:Trichuris trichiura,the human whipworm.It ' s hard to top Blaine ' s excellent description of the diagnostic features for this case:"Trichuris trichiura. If the eggs in utero were not enough, there is also stichocytes and bacillary bands (best seen in the anterior end of the worm within the tissue), polymyarian/coelomyarian musculature, and a strongly nucleated hypodermis. The size and egg morphology rules-outCapillaria philippinensis, which would also be in the intestinal tract and have trichuroid features of stichocytes and bacillary bands. "William Sears also pointed out a helpful feature: " it is telling that th...

Answer to Case 306
Answer: Trichuris trichiura (whipworm)This was a tough case, as evidenced by the responses I received. Most of us are not taught the features of worms in histologic sections, but they not uncommonly pop up and pathologists and microbiologists alike are called upon to identify them. In this case, the characteristic features of this nematode include variable diameter along the length of the organism, stichosome, bacillary band, annulated cuticle and nucleated hypodermis. A few of these features are highlighted in the images below. Thank you all for taking a chance on this one and writing in with your ...

Answer to Case 269
Answer: Trichuris trichiura, (a.k.a. Whipworm), adult female. The overall shape of the worm (resembling a whip) is diagnostic, as are the outlines of the characteristic eggs seen within the worm (compare to the egg that I superimposed on the image):With a little imagination, you can see where the bipolar plugs of the intrauterine eggs are. The presence of eggs lets us know that this is a female. Also, the tail (the thicker portion of the worm) is not curled; males have curled tails while females have straight tails.So the answer to the bonus question (as alluded to above) is that the end shown below is the head...
