Multon tape worm of dogs (T. ovis)
Simple Fecal Flotation
Estimated made of number of parasite ova per gram of feces. This technique used on small amount of fecal material found on end of thermometer.

Pooled Sample
Obtain from group of animals house together
Simple Fecal Flotation
Principles: Diff in specific gravity of parasite egg & cysts from fecal debris in solution
Baermann technique
Contrast to previous method mention use to recover parasite larva not ova
Common flotation medium of Simple Fecal Flotation Technique
Sodium nitrate
Other popular solutions of Simple Fecal Flotation Technique
Sheathers and Zinc Sulfate
Zinc Sulfate
Concentrating cystic form of available in Vet supply protozoans
Sheathers
Aka sugar quite sticky tend to float between egg and inexpensive
Centrifugation technique
Efficient recovering parasite ova from sample. Require little more specialized equipment
(Tick) Ambiyomma americanum
Mammals, including human (intermediate host; small mammals)
Gross examination
Upon receiving fecal sample, gross exam first performed to examine physical characteristics
Gross parasites
Parasite may visible upon examination. Most common seen on dogs cat feces these are roundworms proglottids of tapeworms.
