request if any one can help in identifying them.
regards,
Sapna.
Dear Sapna,
A detailed morphological study is requerid for the correct identification of the parasite. I think it can be an encysted metacercariae of Strigeidae (Trematoda). Maybe it is a species of Ichthyocotylurus. Please see the Fig 6 of the attached paper.
Good luck with your study,
Best regards,
Hudson
thank u sir for answering d question n recommendation.ya sir morphological character are must for perfect identification, i will focus on dis point. i m working on helminth parasites sir. if there are any references guide for identifying them please do suggest.i will be thankful.
thanks fr d wishes sir

Hi, did you try to remove the membrane and then examine it carefully. good luck.
hello,no i havent as i was not totally confirm abt the identification of the parasite.,so thinking that it may damage the internal structure of this parasite if i remove d covering n even i had collected just few of them .but surely i vl try removing d outer sheath n vl study.thanks for the valuable suggestion.
with regards,
sapna.
Yes, I too agree with Hudson Alves Pinto it can be an encysted metacercariae of Strigeidae (Trematoda).
Dear Sapna,
They may also be dilepidid type tapeworm larvae or some other helminth. Typically strigeid cysts don't have "tails" like that but my suspicion is that it is part of the cyst, not the parasite. As Hudson and others have suggested, one cannot be sure unless you do more detailed morphological work. I would recommend breaking open one cyst and temporarily mounting it on a slide with saline or water (if they are already fixed) and taking a look. You can rule out dilepidid cestodes I'd you don't see rostellar hooks, and you can rule out acanthocephalans if you don't see a proboscis with hooks.
dear Choudhary sir,
thk u sir for ur valuable suggestion.vl follow the instruction wat u mentioned.
