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

A modified zinc sulfate centrifugal flotation technique is described. It has proved satisfactory for detection of protozoan cysts and helminth eggs, such as Schistosoma mansoni, Clonorchis sinensis, Trichostrongylus spp. and Trichuris trichiura. When five specimens were examined the efficiency of the method for detection of T. trichiura eggs was 100%.

Now that prepared flotation solutions and high-quality, inexpensive swinging bucket centrifuges can be purchased from several commercial sources, it is much easier to adopt centrifugal flotation techniques.

CDC - DPDx - Diagnostic Procedures - Stool Specimens

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.

Fecal Centrifugation - KSVDL

Centrifugation recovers 3-5 times as many eggs over other passive floatation techniques, such as the Ovassay®. Passive flotation is especially poor at floating whipworms, missing almost 2/3 of all whipworm infections completely. We advocate the use of centrifugal fecal flotation as part of a comprehensive parasite control plan for dogs and cats.
