When newly hatched chicks are inoculated with a Salmonella strain, they induce a rapid onset of resistance to intestinal colonization by other Salmonella strains. The exact mechanism of this early colonization-inhibition is not known. To study host-related contributions to this phenomenon, the kinetics of immune cell infiltration in the caecal wall was analyzed during the first 10 days after vaccination of newly hatched chickens with a Salmonella enterica serovar Enteritidis aroA mutant, and infection 1 day later with a virulent S. enterica serovar Enteritidis strain. These data were correl…
