Serological Testing for Trichinosis in Pigs

摘要

A test system suitable for rapid and economical screening of large numbers of swine for antibodies to Trichinella spiralis is being developed. It was demonstrated that the soluble antigen-fluorescent antibody (SAFA) test can detect T. spiralis antibodies earlier and in swine fed fewer larvae than other tests. An enzyme-labeled antibody test (ELA) is being developed which is similar in principle to SAFA, but was shown to be more sensitive than SAFA by comparison in a double blind test on sera from experimentally infected pigs.
