Figure 2. Cecal persistence and colonization levels of S. Senftenberg isolates in infected chicks.

Figure 2

Number of CFU of Salmonella Senftenberg rifampicin-resistant strains per gram of cecum of chicks orally infected with 105 CFU. (A) Enumeration was performed up to 33 days post-infection for strains SS304, SS308, SS270, SS267, and 26 days p.i for strains SS17, SS291, SS209, SS13, SS48, SS47, SS278, SS41. (B) Cecal load of chicks inoculated with four selected strains (SS308, SS209, SS304, SS278) in a second experiment up to 26 days p.i. The data presented correspond to the mean of positive and negative cecum samples ± SEM.
