Enzyme-linked immunoelectrotransfer blot (EITB) using crude worm antigen of adult Paragonimus westermani was performed for human patients sera to identify the species-specific components. Crude antigen was obtained by homogenizing and centrifuging 24-week old adult worms at 10,000 rpm for 60 minutes in phosphate buffered saline (PBS, pH 7.2) containing phenyl methyl sulfonyl fluoride (PMSF). Gradient sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS-PAGE) was performed and blotted electrophoretically onto a sheet of nitrocellulose paper. The sheet was cut into strips and exposed to sera diluted 1: 200 with PBS. SDS-PAGE showed 26 protein bands ranging 229 to 10 kDa. Of them 229, 91, 60, 50, 35-31, 27, 25, 21, 17, 11 and 10 kDa components showed positive reaction with serum antibody of patients with P. westermani. Sera of patients infected with Clonorchis sinensis reacted with 35-31, 19, and 11 kDa bands. Human sera from cysticercosis and diphyllobothriasis cases showed non-specific cross reactions with 229, 35-31, 27, 25 and 17 kDa bands. Protein bands of 91, 60, 21 and 10 kDa showed strong positive reaction without cross reactions with sera from other helminthic infections.
