Three hundred stool samples for routine ova and parasite examination were examined as saline and iodine wet preparations, the results were then compared with the Zeihl-Neelsen-modified Acid Fast staining (MAFS), as the oocysts are acid fast in character. Examination with saline preparation was unable to detect any oocyst, while iodine preparation yielded three oocyst and stained smears with MAFS revealed five positive stool samples.
