Module 2: Introduction to Common Fecal Diagnostic Procedures
Did I find a parasite egg?
You have finally made it to the finish line, your condenser on your microscope is down and you focus on…something…but what is it? It is your job now to determine if this is a pathogenic parasite, spurious parasite, or simply a pseudoparasite.
Parasite egg and pseudoparasite resources:
There are many resources available to you here is a list of a few:
- Your parasite manual (See link in Module 2 assignment)
- CAPCvet parasite egg identifier phone app (free): Apple Store & Google Play
- CAPCvet website
- Fecal flotation is the main method for intestinal parasite screening
- We have other fecal tests to look for specific parasite ova, trophozoites, or larvae
- Fresh feces should always be used to perform these tests when possible
- Just because you find an egg, oocyst, larvae, etc. on a fecal examination, does not mean that it is pathogenic or the cause of disease in your patient
- Pollon is one of the most commonly misidentified structures as parasite ova
an incidental finding. An example of a spurious parasite is finding rabbit coccidia in a dog fecal exam.
an object or organism that resembles or is mistaken for a parasite.
