Figure 2. ELISA results for paragonimiasis (Pa), cysticercosis (Ts) and toxocariasis (Tc) from 208 persons.

The surveyed persons (n = 208) include 168 and 40 (20 persons from Cameroon (Nc) and 20 from Japan (Nj)) with and without symptoms, respectively. ○, samples with Paragonimus eggs in the sputum. Serology could detect more cases than microscopical examination of sputum and was expected to be more sensitive for detection of paragonimiasis including immature adult stage [11]. ◊, samples positive against the recombinant antigen 100% specific to cysticercosis by immunoblot [17]. The broken line denotes the respective cut-off value for each disease and each cut-off value is shown.
