[The influence of viscosity on adhesion and invasion of Salmonella strains in an in vitro model].

The influence of viscosity on the adhesion and invasion behaviour of Salmonella strains of different origin was investigated using an in-vitro-model. These processes seem to be strain-dependent. Compared to the controls, the number of internalized Salmonella was elevated. This increase was a result of the greater number of Salmonella which adhered to Caco-2-cells and was detected only for strains from organs of calves having died from salmonellosis. The average motility of these strains was determined to be 1.6 +/- 0.5 mm/h. A possible association between adhesion ability and motility was discussed.
