PHIL Image 1538

Under a high magnification of 400X, this photomicrograph revealed some of the ultrastructural morphology exhibited by a trematode, Fasciolopsis buski, egg, which is described as broadly ellipsoidal, operculated and measuring 130µm to 150µm long, by 60 µm to 90µm wide. These eggs are unembryonated when passed in feces. The eggs of F. buski can be difficult to distinguish fromFasciola hepatica, although the abopercular end of the latter often has a roughened or irregular area.

Clinical Features:
Most infections are light and asymptomatic. In heavier infections, symptoms include diarrhea, abdominal pain, fever, ascites, anasarca and intestinal obstruction.
Laboratory Diagnosis:
Microscopic identification of eggs, or more rarely of the adult flukes, in the stool or vomitus is the basis of specific diagnosis. The eggs are indistinguishable from those of Fasciola hepatica.
