Flotation Technique for Fecal Parasite Concentration

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

The Modified Wisconsin Sugar Flotation Technique

The “Modified Wisconsin Sugar Flotation Technique” is the best of all techniques for this task: 1. The “Modified Wisconsin Sugar Flotation Technique” has a high degree of sensitivity for use in animals producing large volume of manure such as lactating dairy cows or feedlot cattle on “full” feed. Part of the reason the “Modified Wisconsin Sugar Flotation Technique” produces

CDC DPDx Diagnostic Procedures Stool Specimens

2016-05-03· 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. The disadvantages of most flotation techniques are that

Zinc sulphate addition point (Pb/Zn flotation) Froth

ZnSO4 should be added in the grinding circuit and a small dosage in the flotation circuit. Also, it' is common to add ZnSO4 in the regrind circuit. The dosage and distribution depends on the mineralogical characteristics of the ore. For example, if there is activated sphalerite in the lead or copper flotation circuit, the addition of zinc sulphate will not be very useful. It is important to

Zinc sulphate flotation of faeces. CAB Direct

The zinc sulfate flotation technique for the concentration of eggs in faeces has been compared with the results of direct microscopical examination of faeces, and the tabulated results show that the zinc sulfate technique has great advantages over the faecal film in cases of infection with Ascaris lumbricoides, Trichuris trichiura, Ancylostoma sp. and Enterobius vermicularis, but in Taenia spp....

Comparative evaluation of a modified zinc sulfate

A modified zinc sulfate flotation technique using Formalinized fecal specimens (F-ZnSO4) was compared to the Formalin-ether (FE) concentration method for the laboratory diagnosis of intestinal parasites. Many laboratories have difficulty storing, using, and disposing of either and need a procedure for concentrating fecal specimens which does not require ether. Comparative data were obtained

The use of the zinc sulphate centrifugation flotation

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%.
