Oocysts or artifacts in wallaby centrifugal fecal float

Hi there, I’m a vet student working at a small zoo/aquarium type of place for a clinical rotation. I’m working on analyzing biosecurity protocols and cross-contamination risks so I did some centrifugal fecal floatations with fresh feces & fecal-sol from a bunch of different mammals. I recently made a similar post but for rabbits.

These pictures are mainly from the 40x and 100x objective lenses (the coccidia looking oocysts at 40x and tapeworm looking oocysts at 100x) is from wallabies, one of which has been having intermittent soft stool but no other clinical signs. They eat wallaby pellets, hay, and some fresh veggies. Their water dishes are cleaned every morning with hot water and soap and refilled with fresh water twice daily. The enclosure is spot cleaned twice daily and fully cleaned out every week or so.

All animals are tested frequently, and receive routine veterinary care, fecal checks, and annual exams. I just wanted to check if these are actually coccidia and tapeworm oocysts (plus maybe a couple other things like I think one might be f. buski as their enclosure is directly adjacent to pigs), or if it’s just artifact/debris. Any help is appreciated!

Is this an oocyst or plant/pollen artifact?

Hi there, I’m a vet student working at a small zoo/aquarium type of place for a clinical rotation. I’m working on analyzing biosecurity protocols and cross-contamination risks so I did some centrifugal fecal floatations with fresh feces & fecal-sol from a bunch of different mammals.

This sample pictured (I believe this view is with the 20x objective lens) is from a rabbit, who is not currently displaying any clinical signs. Other stuff I found within the same sample, I’ve already identified as pollen artifact, but this one is making me suspicious. She eats fresh greens and rare berry treats in addition to her hay and rabbit pellets. Her water is cleaned every morning and refilled with fresh water twice daily. Bedding is changed as needed and she is litter box trained which gets cleaned out daily as well.

The other animals I’ve tested, I found a bunch of stuff even though they test frequently, so parasites aren’t unheard of here for sure. I’m just unsure if this is actually some sort of oocyst like cystoisospora, eimeria, or something, or if it’s just artifact/debris. Any help is appreciated!
