Correlation between bacteriology of lymph nodes and serology for Salmonella diagnosis in slaughter pigs

Abstract

Salmonella control programs in pigs are usually based on serological tests. The major objective of this cross-sectional study was to investigate the correlation between the serological results and the bacteriological results of Salmonella diagnosis in pigs at the herd level and at the animal level. From 60 farrow-to-finish herds, serum samples and mesenterial lymph nodes from 30 fattening pigs were taken in the slaughterhouse
