Case of the Week 468

The week I am re-posting a previous case that was kindly donated by Dr. Julie Ribes. I've chosen to repost the case because it is quite interesting, but also because I have some important new information to share with you about the identification. I'll post the (newly-modified) answer this Friday.

The following material was obtained from an ostomy bag.


Identification?

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.

It was clearly a Creepy Dreadful Wonderful Pseudo parasite!
But banana seeds?!? I had no idea! I'm learning really cool stuff here!
I love it!

I remember this one! It is the banana experiment. Great work!

I wonder if this indicates that banana seed germination is facilitated by passage through the digestive system of an herbivore.

Have you tried growing any of them into banana trees?

Banana sp is as specific as I can be.

I hope with all my heart that you are going to teach us to speciate bananas based on their pseudouteri

Inclined to go with banana.
(Almost looks like proglottid uteri but it would not be this color unstained)

Looks like everyone agrees that this is banana, however do we know for certain which one? With the newly arrived immigrants from Asia, besides the mundane bananas sold at supermarkets throughout the country, Floridians have a newly opened horizon when it comes to banana business. There are the Spanish plantains, to the plump and short yellow ones, to the fully seeded ones which can only be eaten green, there is also a yellow small one just as long as 12cm but the best ones are those tiny thumb sized so good they are fit for the Gods.

It's pretty terrible that you're joking about this, this is why lyme disease goes untreated. If you see this come out of you try the salt/c protocol, because you probably have lymes.
