چکیده

Pigs were exposed to various levels of Salmonella enterica subsp. enterica serovar Typhimurium by either intranasal inoculation or by subjecting them to a contaminated environment. More than 10(3) salmonellae were required to induce acute Salmonella infection. These results indicate that intervention against acute Salmonella infection in lairage may be more readily achieved than previously thought.

In this thesis two feed-associated serotypes (S Cubana and S Yoruba) were compared with two serotypes commonly detected in pigs (S Typhimurium and S Derby). The overall aim of the thesis was to increase knowledge about the ...

An update on pathogenesis and control of Salmonella infections in pigs

In order to be able to come up with efficient control measures to combat Salmonella infections in pigs, for example by means of vaccination, detailed knowledge of the pathogenesis should be the starting point. Transmission of Salmonella between pigs is thought to occur mainly via the faecal–oral route. Depending on the inoculation dose and the used strain, experimental oral infection of pigs wi...

Salmonella Fecal Shedding and Immune Responses are Dose- and Serotype- Dependent in Pigs

Despite the public health importance of Salmonella infection in pigs, little is known about the associated dynamics of fecal shedding and immunity. In this study, we investigated the transitions of pigs through the states of Salmonella fecal shedding and immune response post-Salmonella inoculation as affected by the challenge dose and serotype. Continuous-time multistate Markov models were deve...
