Fecal flotation is a routine veterinary test used to diagnose internal parasites or worms. The test detects the eggs of mature parasites that live inside the body and pass their eggs to the outside by shedding them into the hosts stool. Some of these parasites are worm-like while others are tiny single-celled organisms called protooa.
A Modification of the Zinc Sulphate Centrifugal Flotation Technique The inc sulphate centrifugal flotation technique of Faust and his associates 1938 1939 has proved to be of such value in the concentration of helminth ova Get Price Flotation Technique for Fecal Parasite Concentration Methods This technique is predominantly used .
The flotation solution itself and its specific gravity could affect the recovery rate of ova. Ajala and Asalou 23 demonstrated that when they used a inc sulphate solution versus a sodium nitrate solution the mean recovery rate for inc sulphate was lower compared with sodium nitrate 13.9 vs 25.0.
