This study aimed to determine the cause of acute recidivous @entity110 in @entity1 who usually eat fish or other seafood. Twenty-five @entity1 were studied. The skin prick test with larval @entity1542 extract was performed; total and specific IgE against A. simplex was measured with the CAP System; specific antibodies to A. simplex were determined by ELISA; and immunorecognition patterns of the sera were studied by Western blot. Nineteen @entity1 showed specific IgE to A. simplex, but specific IgE to Ascaris was demonstrated in only two @entity1 . No @entity1 reacted to @entity5603 or Echinoccocus granulosus antigens with the same test. The skin prick test was positive in 16 @entity1 , in two of them persisting for 48 h. Five @entity1 showed neither skin reaction nor specific IgE to A. simplex. Sera showed specific immunoglobulin levels against A. simplex larval crude extract, by both ELISA and Western blot. Likewise, specific immunoglobulin levels against excretory-secretory antigen were also measured by ELISA. Only one @entity1 showed sensitization to fish. A. simplex was found to be the main cause of acute recidivous @entity110 in @entity1 who usually eat fish and are not sensitized to it.
