Comparison of culture ELISA and PCR techniques for salmonella detection in faecal samples for cattle pig and poultry

摘要

BackgroundPerformances of different salmonella detection methods were evaluated by applying them to of artificially contaminated faecal specimens from cattle, pigs and poultry. The NMKL71 method, being the standard reference method for detection of salmonella in the official Swedish control program, was compared with the proposed ISO method using MSRV-selective enrichment for culturing, and also with three commercial ELISA- based systems, Bioline Selecta, Bioline Optima and Vidas, a commercial PCR-based method, BAX^® system, and three different strategies using PCR detection using a non-commercial PCR system.
