Zinc Sulfate Centrifugal Floatation.

Zinc Sulfate Centrifugal Floatation.

When concentrating protozoan cysts and helminth larvae and eggs by centrifuging in zinc sulfate, Frank adds a few drops of collodion diluted with an alcohol-ether mixture. This forms a surface film to which cysts, eggs and larvae adhere during centrifugation. It can be lifted off intact by means of two sticks and examined in the usual way under a microscope.

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%.

Zinc sulfate was initially proposed as a general-purpose centrifugal flotation solution for protozoan cysts and helminth eggs in human feces in 1939.6 Because of the suc-cess of ZnSO 4 in floating Giardia cysts, its use in veteri-nary practices appears to be increasing. However, some practitioners and technicians have adopted the flotation
