Results of the four multiplexes after testing DNA isolated from the inoculation cocktail. The PCR multiplexes showed that all 17 strains were present in the cocktail before animal inoculation. Lane M: 100-bp marker; lane C: DNA isolated from the experimental cocktail; lane N: negative control. Gels: A - Chicken-Human multiplex; B - Cattle multiplex; C - Pig multiplex; D - Mix multiplex. Asterisks (*) denote strain-specific PCR signals
