This week's case was generously donated by Drs. Mauro Saio and David Hamer. The patient is a middle-aged male who noted the following objects in his stool. Individually, they measured approximately 1 cm in length. Identification?
This is a learning session for me. Have not seen citrus infestations in domestic animals.
I do have a suggestion which would help differentiate plant material from parasites. I always keep a dropper bottle of Iodine near my microscope. When in doubt I challenge the material with a drop of Iodine which stains starches. I've used it on banana strings, onion slices and sesame seeds ( which look much like Mesocestoides segments). I don't know if citrus residues have enough starch to react with Iodine.
These "parasites" don't have a head, not a tail and no guys. Definitely not parasites. As mentioned above, they are more compatible with citrus fruit cells. Unable to associate with any particular cultivar. Florida Fan
First, I am not a citrus expert and will not try to associate the objects to any cultivar. We have these oranges: Navel, Hamlin, Pineapple, Ambersweet and Valencia. For grapefruit Florida grows: Ruby Red, Flame, Thompson, Marsh and Duncan. For tangerines: Fallglo and Sunburst. For tangelo: Minneola, Orlando, Nova, Sampson. We also have Murcott, Tangor, Calamondin, Mandarin Osceola to name a few. So you see, any attempt at the identification is would be fruitless. Have a little fun time, Florida Fan
It is little known that in Minnesota, a single species of native flora grows which is a member of the citrus family Rutaceae. Commonly called prickly ash (Zanthoxylum americanum) have small fruits not much more than a thin coating surrounding the seeds. They have no resemblance to those wonderful varieties noted by Florida Fan. They do have a citrusy oder. They are mostly known for their terrible thorns that can shed the flesh of inattentive hikers.
A note to Florida Fan. I am envious, I live to pick a fresh citrus right from the tree.
Every week I will post a new Case, along with the answer to the previous case. Please feel free to write in with your answers, comments, and questions. Also check out my image archive website at http://parasitewonders.com. Enjoy!

Citrus infestation.
I think the same as my predecessor: citrus residues.

orange you guys clever to come up with this diagnosis...
didn't have to squeeze Bobbi for too much information...
Your efforts have been fruitful...
