Sites: Gut
Paragonimus sp. egg in faeces 79 x 48 microns operculate and unembryonated -- saline preparation. This was from an Australian patient who returned from travelling in Ecuador, South America. Paragonimus eggs can be confused with D. latum eggs (65-70 x 45-50 microns and smooth shell, in N. Europe, Siberia, N.America) ) because of size overlap but the Paragonimus eggs have opercular shoulders and a marked thickening of the shell at the abopercular end, not seen in D.latum eggs (Garcia and Bruckner,1997). The patient was asymptomatic although she did have an abnormal brassy cough. The eggs are most likely those of the P.mexicanus group considering the appearance of the eggs and her travel itinerary. (P.westermanni eggs 70-100 x 38-50 microns found in SE Asia, China, Japan and USSR)
