A fecal flotation test is normally used to detect the fecally-shed eggs (and sometimes the larvae) of various parasitic worm species as well as the oocysts shed into the droppings by various, replicating protozoan organisms.
The results will help the trainers to decide whether if it is time to deworm the horses.
The equipment that we are using for this test is the Fecalyzer®.
- Lift cap and remove green insert. place 1 gram of fecal sample into valve can fill it the FECALYZER® Flotation Medium.
- Rotate green insert vial back and forth to separate ova from fecal sample. Mix thoroughly
- Seat green insert vial firmly in place.
- Fill holder completely with additional FECALYZER Flotation Medium to the brim to form a meniscus.
- Cover the float 22mm cover slip on meniscus for 15-20 minutes.
- Transfer the cover slip to a microscopic glass slide and examine it under the microscope under 40-100x magnification.
Here are some of the pictures or parasite eggs:
- Isospora oocyst (extreme close-up - 1000x) starting to undergo maturation to its infectious state
- A Spirometra tapeworm egg under 1000x oil immersion.
- a Whipworm or Trichuris vulpis egg under 1000x oil immersion.
