Hmmm. This is probably a case of acanthocephaliasis (thorny-headed worm infection), which I'm basing on what appears to be an armed proboscis protruding from the worm (figure 2). Based upon the egg morphology in figure 3, I'll go with Moniliformis moniliformis. I wouldn't be too surprised if this patient ate a cockroach or other beetle (intermediate hosts of these parasites) while orally sampling his/her environment. Good case!
My guess is enterobius vernicularis given the child history and the egg looks like an early egg morphology. The worm, maybe the female mouth?
It is one of the Thorny-Headed worms or Acanthocephalids, I don't know which.
The worm is an acanthocephalan or 'thorny headed worm' - the prescence of the barded probocis is indicative of this. Im not sure about the species but I dont think it is Monliformis monliformis as this species has a segmented appearance given the horizontal markings on this species which I cant easily see on this specimen, so Ill go with Macracanthorhynchus hirudinaceus - the giant thorny headed worm of swine which can occasionaly infect humans and dogs and uses beetles of the Melolontha genus as intermidiate hosts.
The egg could belong to the Acanthocephalan but i think this species has a thicker egg cuticle so therefore, I thin k the toddler is coinfected with E.verminicularis.
It looks like ascaris to me. Too big for a pinworm.
i think that's enterobius vermicularis.
Looks like Moniliformis moniliformis.
It is thorny headed worm and eggs like Moniliformis not Macracanthorhynchus eggs. Bolbosoma sp is antoher but I have not seen the eggs or adultsthansk for sharing
I agree with Brent! Nice case!
Very nice case, never seen this one before
