How do you identify Schistosoma haematobium?

haematobium almost always have microscopic blood in their urine which can be detected by chemical reagent strips. The eggs of intestinal schistosomiasis can be detected in faecal specimens through a technique using methylene blue-stained cellophane soaked in glycerin or glass slides, known as the Kato-Katz technique.

What does a haematobium egg look like?

S. haematobium eggs are ovoid in shape with a terminal spine. The egg measures about 83-187 micrometers by 60-70 micrometers and can be seen in urine or stool when viewed with a microscope. At the site of their deposition, the eggs lie in chainlike rows within small veins.
