Flotation Technique for Fecal Parasite Concentration Methods

This technique is predominantly used in parasitology laboratories. By exploiting the density of the parasites, particularly eggs, it allows the parasites to float to the top of a dense solution (final specific gravity of about 1.20) and can then be skimmed from the top of the tube.. The most commonly used reagent is zinc sulphate.Operculated eggs as well as schistosoma and infertile Ascaris

Oct 01, 2016· 1. Introduction. There are a variety of techniques for recovering parasite eggs in fecal matter, including the direct smear method, the flotation method, and the centrifugal flotation or sedimentation method; however, a reliable and convenient method for recovering helminth eggs from soil had not been developed.

May 03, 2016· Flotation techniques (most frequently used: zinc sulfate or Sheather’s sugar) use solutions which have higher specific gravity than the organisms to be floated so that the organisms rise to the top and the debris sinks to the bottom. The main advantage of this technique is to produce a cleaner material than the sedimentation technique.

Faecal sedimentation: Principle

The majority of trematode eggs are too large and heavy to float reliably in the flotation fluids normally used for nematode eggs. They do however sink rapidly to the bottom of a faecal/water suspension and this is the basis of the faecal sedimentation technique.

Interpretation The Alexon Cryptosporidium Monoclonal Antigen Capture Enzyme-linked Immunosorbent Assay (ELISA) is a fecal procedure designed to detect a Cryptosporidium specific antigen. This procedure is done in parallel with a double centrifugation concentration flotation procedure for Cryptosporidium oocysts and any other parasites that may be present in the fecal sample.

Diagnosis of Internal Parasites Today's Veterinary Practice

Fecal Flotation. Fecal flotation remains the most common method to detect helminth eggs and protozoan cysts. Flotation Solutions. Based on the SG differences of the various parts of a fecal sample (feces, ova, cysts, debris), the recovered eggs are lighter (ie, lower SG) than the flotation solution and will float to the surface.

Common Laboratory Procedures for Diagnosing Parasitism

Flotation solutions usually have specific gravities between 1.2 and 1.25. In this range, fecal material, much of which has a specific gravity of 1.3 or greater, does not float ( Figure 17-10 ). The result of using flotation solutions is that parasite eggs float to the surface of the liquid and large particles of fecal material sink to the

Yes. Fecal flotation is just the first step. If repeat fecal flotation tests are negative and a parasitic infection is still suspected, then your veterinarian may recommend other tests such as doing a fecal wet mount, using concentration methods, using stool preservatives, or doing a fecal Baermann etc.
