|Description:||Magnified 128X this photomicrograph revealed the presence of a single trematode, Fasciolopsis buski, egg, which is described as broadly ellipsoidal, operculated and measuring 130Ám to 150Ám long, by 60 Ám to 90Ám wide. The eggs are unembryonated when passed in feces. The eggs of F. buski can be difficult to distinguish from Fasciola hepatica, although the abopercular end of the latter often has a roughened or irregular area.|
Most infections are light and asymptomatic. In heavier infections, symptoms include diarrhea, abdominal pain, fever, ascites, anasarca and intestinal obstruction.
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.
