How should faecal examination be performed?
Direct examination of faecal smears for oocysts under an optical microscope is not very conclusive, but certainly can be successful where massive infestation is present. However, it will be necessary to concentrate the samples first. Remember that flotation solutions with higher specific gravity are more suitable for use when flotation is to be carried out. A saturated NaCl solution with 500 g added glucose per litre can be used as flotation medium. This yields higher numbers of oocysts, which are also more clearly visible.
