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%.
