title: Evaluation of different antigens in a seroepizootiological survey of trichinellosis by enzyme-linked immunosorbent assay.
abstract: Antigen isolated from the large-particle fraction of the muscle Trichinella spiralis larvae (PAW), excretory/secretory (E/S) and crude worm extract (CWE) antigens were evaluated in a seroepizootiological survey of trichinellosis by the enzyme-linked immunosorbent assay (ELISA). The ELISA using PAW antigen yielded 16 positive animals (1.6%), E/S antigen revealed 21 (2.1%) positive, and the highest number of positive (23 or 2.3%) were obtained using CWE antigen. Parasitological post-mortem examination of all seropositive animals showed five and seven false-positive animals when E/S and CWE antigens were used, respectively.
