good question

I agree with Dr.stephan

regards

Dear Stefen I found 2 parasite in stomach each one enveloped with a sheath I think its Physaloptera

They are very likely Physaloptera spp. nematode. They are certainly nematodes.

I agree it's difficult to see the parasite in the picture. If that I see is it, It likse a nematode.

this is the same parasite

thank you dr. Dhia

Dear Dr. Hayder,

If this worm is nematode, may be Toxocara cati or Toxoxcaris leonina..., put it in lactophenol for several days then examine under light microscope.

I don't know the objective behind this question but one thing I would like advise that the house members should be evaluated as well to rule out a common source of this worm infestation and save them from complication by timely diagnosis and treatment.

seems to be Toxocara. Usually lives in smll intestine, and come into stomach by vomiturition, especially if some worms are dieing and produce intoxication. toxins of this worm are neurotoxic- producing encefalosis and neurovegetative troubles

Physaloptera praeputialis is a good guess.
