Abstract

We examined 120 stool specimens from patients with diarrheal disease, suspected of being infected with Cryptosporidium. Preliminary observation was made with a Lugol-Nigrosine stain and confirmation with modified Ziehl-Neelsen. Twenty specimens (12 from children and 8 from adults) (16.6%) were positive for Cryptosporidium oocysts andevery one of them was confirmed with ZN stain. Since It may be difficult to detect low-prevalence parasites we suggest routine use of Lugol-Nigrosine which is useful for the detection of Cryptosporidium as well as of other protozoa.
