Under a low magnification of 78X, and stained using an indirect fluorescent antibody (IFA) test, this photomicrograph confirmed the presence of Schistosoma mansoni trematodes.

Laboratory Diagnosis for Schistosomiasis:

Microscopic identification of eggs in stool or urine is the most practical method for diagnosis. Stool examination should be performed when infection with S. mansoni or S. japonicum is suspected, and urine examination should be performed if S. haematobium is suspected. Eggs can be present in the stool in infections with all Schistosoma species. The examination can be performed on a simple smear (1 to 2 mg of fecal material).
