The effect of oral inoculation with a defined culture of cecal bacteria and provision of dietary lactose on colonization resistance to invasive Salmonella enteritidis was evaluated in leghorn chicks. A defined mixed culture composed of 11 indigenous cecal bacteria capable of utilizing lactose or lactose fermentation products as a primary carbon source was isolated and maintained in continuous-flow culture. Combined treatment with the defined culture and dietary lactose significantly decreased (P < 0.01) the number of Salmonella in the cecal contents and the number of Salmonella cecal-culture-positive chicks in four replicated trials. Additionally, Salmonella colonization of the spleen, liver, and cecal tonsils was significantly decreased (P < 0.05) in each of the trials. The results indicate that the resistance of leghorn chicks to S. enteritidis cecal and organ colonization is effectively increased by inoculation with a defined culture of cecal bacteria and provision of lactose in the diet.

Organ Invasion

Salmonella enteritidis (SE) is of great concern to the poultry industry due to the organism's ability to penetrate the intestinal mucosa of the laying hen and subsequently colonize the ovaries and yolk membrane. The resultant subclinical infection can lead to SE infection of raw eggs and egg products. Interference with the ability of the organism to invade has been linked to the activation and recruitment of inflammatory polymorphonuclear cells, heterophils, to the lamina propria of the intestinal tract.Recently it has been established that heterophil activation and increased resistance to SE organ invasion can be accomplished by the administration of SE-immune lymphokines (SE-ILK) obtained from supernatants of concanavalin-A stimulated SE immune T lymphocytes from SE hyperimmunized hens. Invasion of SE into the lamina propria provides a secondary signal for directing activated heterophils to the site of SE invasion.
