Salmonella Typhimurium resides largely as an extracellular pathogen in porcine tonsils, independently of biofilm-associated genes csgA, csgD and adrA

Original language description

The aim of this study was to determine whether Salmonella Typhimurium resides predominantly intra- or extracellularly in tonsils of pigs and to examine the contribution of biofilm-associated genes csgA, csgD and adrA. Single cell suspensions were prepared from tonsils of orally inoculated pigs to determine the ratio of extracellular versus intracellular bacteria. Both at 5 and 28 days post-inoculation (pi), the majority of Salmonella bacteria was found extracellularly in porcine tonsils. To determine the contribution of biofilm formation in extracellular persistence, pigs were orally inoculated with a mixture of Salmonella Typhimurium wild type strain and csgA, csgD or adrA mutants. At 10 days pi, equal numbers of both wild type and mutant Salmonella bacteria were found not only in tonsils, but also in ileum, ileum contents, ileocecal lymph nodes and faeces. In conclusion, we showed that Salmonella Typhimurium resides extracellularly in porcine tonsils, using a biofilm independent mech
