Diagnostic Significance of EPG and EPD in Experimental Infection of Dogs with Paragonimus westermani (original) (raw)

Abstract

Two dogs were administered with 19 and 38 metacercariae of Paragonimus westermani collected from fresh-water carbs. Eggs began to be detected from the feces 72 and 73 days after administration. EPG and EPD showed so marked a daily fluctuation that it was necessary to calculate a monthly average value of EPD before making a definite diagnosis. This value increased with the lapse of time, although it showed a slight decrease in one dog once for 9 months and in the other dog twice for 16 months, as compared with the value in the preceding month.
