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.

Giardia cysts can be detected in fecal flotations (best with centrifugation or Zinc Sulfate technique) and occasionally one can detect the motile trophozoites in a direct fecal smear. Sometimes the cysts are shed only intermittently requiring multiple fecal samples to be evaluated before they are detected.

zinc sulfate flotation concentration zinc sulfate flotation concentration a method using saturated zinc sulfate to separate parasitic elements from fecal debris through differences in specific gravity; most parasitic cysts, oocysts, spores, eggs, and larvae can be found in the surface film after centrifugation.

Secondly, the Sheather’s sugar solution (Specific gravity of 1.27) used with the Modified Wisconsin Sugar Flotation Technique was equal to or better that magnesium sulfate, zinc sulfate, sodium nitrate, or saturated salt solution in the different species of parasites recovered and in total number of eggs found in the fecal material tested.

Formalin-ethyl ether sedimentation, Formalin-ethyl acetate sedimentation, and zinc sulfate flotation techniques were compared using over 250 clinical parasitology specimens. Fifty positive specimens were identified, and a variety of parasites, including amoebae, flagellates, cestodes, nematodes, and trematodes, were encountered.

Comparison of formalin-ethyl ether sedimentation, formalin-ethyl acetate sedimentation, and zinc sulfate flotation techniques for detection of intestinal parasites.

Fecal flotation works on the principle that most parasite eggs (and some larvae) have a specific gravity of about 1.05 to 1.20 3 so they are less dense than flotation solutions. As a result, parasite eggs (and some larvae) will rise to the surface of the flotation solution.

7. Carefully lift the coverslip with its hanging drop containing parasite eggs and cysts on the underside and mount on a clean slide, liquid side down. A small drop of iodine stain may be placed on the slide prior to adding the coverslip. The slide is gently rotated after adding the coverslip to ensure a uniform mixture.

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.

However, the direct film remains as the method of choice, as it reveals the trophozoites in additiom Laboratories with adequate facilities should perform both techniques. SUMMARY. The direct faecal film and FAUST'S zinc sulphate flotation technique are compared in a series of 1,539 specimens.

ZINC SULFATE CENTRIFUGAL FLOTATION METHOD This technique is predominantly used in veterinary 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.

They can sometimes be detected on fecal floatation, especially zinc sulfate fecal flotation. 2. Dog and cat protozoan parasites that may be diagnosed on fecal flotation: Toxoplasma (Toxoplasmosis): Toxoplasma gondii (definitive host is the cat - oocysts are only shed into the faeces for 1-2 weeks).

Zinc Sulfate Centrifugal Flotation. Fill a 15 ml centrifuge tube with ZnSO 4 solution (1.18 specific gravity) and pour into a glass dish. Using a tongue depressor, push the feces (2 to 3 grams, a piece the size of a grape) through the strainer into the ZnSO 4 solution in the dish. Using a funnel, pour the ZnSO 4-fecal mixture back into the centrifuge tube.
