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.Assessment of the efficacy of autogenous vaccines in Spotty Liver Disease control
This project demonstrated that autogenous vaccination of Campylobacter hepaticus can produce a measurable humoral immune response in layer hens. This humoral response is related to some level of protection against Spotty Liver Disease.
Molecular Diagnostics for Marek’s Disease
This project aimed to develop simple cost-effective sample collection techniques to detect the presence of a vaccine in the blood of vaccinated birds.
