I have no idea what that is but I'm feeling doubtful that its a parasite..

Dreadful looking pseudo parasite. This is one of those we have been requested to identify the terrifying "worm" or "bug" numerous times and for sure this will not be the end of "The Pretender" of that "Monster inside Me".
No, no this ain't no parasite.

Banana! We've seen this many times. The consistency is quite mushy and the black "strings" split into the individual seeds. Perhaps the patient's last meal included a fruit salad �� ECF

Partly digested rhubarb plant fragments?

Fibrinous matter? Does not look parasitic.

Research Lyme Disease. Quite common. I believe the photo shows Borrelia burgdorferi. Read more about it here - http://www.lymephotos.com/bb/

Remember Anon, the spirochete Borrelia burgdorferi is microscopic. It cannot be seen with the naked eye. In fact, it is so small, we can't see it with our normal stains that we use and have to use a special technique called dark-field microscopy in order to see it. Anything that is visible macroscopically (like the material shown here in this case) would not be a spirochete. Also, if you read the answer to this case below, you can see that I've shown this to be banana seeds.
