disadvantages of using zinc sulfate in the fecal centrifugation technique -forms microscopic bubbles that can obscure microscopy -forms crystals that can be confusing
Zinc Sulphate technique. Advantages Zinc sulphate centrifugal flotation technique is useful for the recovery of protozoan cysts and helminthes eggs. Disadvantages Large trematode eggs, some tape worm eggs, and infertile . Ascaris lumbricoides. eggs are not concentrated by this method. Raed Z. Ahmed, Medical Parasitology Lab.,2012
Concentration techniques like simple slat flotation, Zinc sulphate centrifugal floatation, formol-ether concentration and modified formol-ether concentration. Results The prevalence of the intestinal parasitic infections was higher in the rural population. A male predominance was noted 33.29 in both the populations.
In step 3 of zinc sulfate flotation method, Add to within cm of the rim of the tube. thoroughly with an applicator stick 1.5 surface films 1 In step 4 of zinc sulfate flotation method, Centrifuge for minutes. carefully transfer the tube into a rack.
sulphate flotation and centrifugal sedimentation techniques. The frequencies of detection of parasites by each method were determined and the agreement between the diagnostic techniques was evaluated using the kappa index, with 95 confidence intervals. Results The faecal flotation in zinc sulphate diagnosed significantly more cases of
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.
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. In full acceptance of the many uses, limitations and interpretation of worm egg counts, it is easy to
78 A published study revealed that zinc sulfate flotation technique is advantageous over the centrifugal sedimentation method to significantly detect the

Advantages and disadvantages floatation method of separation Products. As a leading global manufacturer of crushing, grinding and mining equipments, we offer advanced, reasonable solutions for any size-reduction requirements including, Advantages and disadvantages floatation method of separation, quarry, aggregate, and different kinds of minerals.
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
Floatation technique. The principle is to use an emulsifying fluid of a greater specific gravity than that of the parasite eggs, which result in flotation of eggs in the solution. Thereby mere examination of the solution in the top most layer will clearly indicate the presence of egg. The faecal material and fiber settle at the bottom.
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
