ABSTRACT

The laboratory detection of parasites requires little specialized apparatus unless culture is done. Motile trophozoites are seen in fresh preparations, but permanent staining is necessary when there is delay in examination. Concentration methods such as formol ethyl acetate are essential for detection of cysts and ova in faeces. For certain parasites special methods are used for detection, for example, culture for Acanthamoeba and Trichomonas, fortified trichrome staining for Microsporidia, tape method for Enterobius.
