Testing the proficiency of the German \u22SALMOTYPE-ELISA\u22 to identify Salmonella antibodies in serum and meat juice from USDA Diagnostic Laboratories

摘要

Antibodies against various Salmonella serovars can be quantitatively detected in serum and meat juice of naturally infected pigs via enzyme immunoassay method (ELISA), and be used for monitoring the Salmonella status of swine herds over time. Ongoing testing of random samples from swine herds via ELISA technique provides, on a herd basis, sufficient information for a \u22Salmonella categorization\u22 of these herd by determining the in-herd prevalence of antisalmonella antibodies.
