Project Type: Appropriated

Start Date: May 24, 2006
End Date: May 23, 2011

Objective:
(1) Determine the persistence of Salmonella in swine manure as affected by dietary treatment. (2) Identify genes important for Salmonella colonization of the swine gastrointestinal tract and persistence in manure.

Approach:
(1) The effects of dietary treatment on the duration of Salmonella persistence in stored swine manure will be determined and a correlation between Salmonella persistence in manure and the native microbial community will be performed. (2) The role of quorum sensing on Salmonella swine colonization, shedding, and persistence in manure will be determined. (3) Genes required for Salmonella survival and persistence in swine manure will be elucidated.
