Evaluation of the duration of immunity induced by a vaccination program against Salmonella Enteritidis 7A in laying hens in Australia (Stage 2).
In this research, a combination of live Salmonella Typhimurium and autogenous Salmonella Enteritidis (SE) vaccine did provide layers with a long- term humoral immune response, but did not prevent the shedding of Salmonella.
Evaluation of vaccination program options against Salmonella Enteritidis 7A in laying hens in Australia
This project tested three different vaccination programs for their efficacy in Salmonella Enteritidis (SE) prevention in laying hens. The results of this study indicated that SE control is possible using a combination of the current registered live Salmonella Typhimurium (ST) vaccines and an SE killed autogenous vaccine.
In Stage two of this project hens vaccinated with the ST + SE program were challenged 35 weeks after their second vaccination. Results indicated that vaccinated hens had a sustained humoral immune response, but were no less likely to be infected with SE long- term than non-vaccinated hens.
