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,
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....
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...
solution (1.18 g/mL) for the flotation process (ZS). Faecal smears from the sedimentation technique were also stained by modified Ziehl-Neelsen (mZN) for coccidian diagnosis. Three slides per sample were examined with each technique. We determined and compared the proportion of . specific parasites identified by each diagnostic
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.
Zinc Sulfate Flotation Solution. Add 386 g of zinc sulfate for every liter of water, while stirring. Heating the water is not necessary but hastens the dissolution process. Using a hydrometer, adjust the solution to a specific gravity of 1.2 to 1.25, as discussed for the sugar solution. Magnesium Sulfate Flotation
Flotation Method Parasitology. Jan 27 2011 Brine floatation technique are used to confirmation the parasite the less weight of the parasite egg or adult worm can be identify by this technique the parasite will be float to the test tube mouth or the bottle mouth and sample can be get from there the specimen like the stool or other type the principle of this test are used the method of a
Oct 17, 2018· 2 Flotation Fluids Since parasite eggs will sink in water, salt or sugar solutions are used to concentrate and separate eggs from most fecal debris The most commonly used flotation fluids are magnesium sulfate (Epsom salts), sugar, sodium nitrate, and zinc sulfate A specific gravity from 12 to 13 is best for floating most eggs
However, the zinc sulfate procedure was more effective for the detection of protozoan cysts, Hymenolepis nana, and hookworm eggs. The results indicate that the Formalin-ethyl acetate procedure provides a suitable alternative to the Formalin-ether method, and they demonstrate the value of using both flotation and sedimentation procedures in the analysis of fecal specimens for parasites.
