Salenvac T against S. Heidelberg and S. Agona
Salmonella Typhimurium , S. Heidelberg and S.
Agona belong to Group B in the Kaufmann-White classification scheme
for Salmonella. S.
Heidelberg studyMethod - Nobilis Salenvac T vaccinated birds and a control group of
unvaccinated chickens were challenged with S. Heidelberg.
- Salmonella shedding through faeces was monitored
for 21 days.
Results The graph below compares
shedding of S. Heidelberg from vaccinated and unvaccinated
chickens. 
Conclusion Nobilis Salenvac T reduces
shedding of Salmonella Heidelberg S. Agona studyMethod - Nobilis Salenvac T vaccinated birds and a control group of
unvaccinated chickens were challenged with S. Agona.
- Salmonella shedding through faeces was monitored
for 21 days.
Results The graph below compares
shedding of S. Agona from vaccinated and unvaccinated
birds. 
Conclusion Nobilis Salenvac T reduces
shedding of Salmonella Agona. top Antibodies in the eggs of vaccinated hens Vaccination of laying hens with Nobilis Salenvac T results in Salmonella antibodies in the eggs. A study showed that growth of Salmonella Enteritidis was significantly reduced in these eggs compared to eggs from unvaccinated hens and hens vaccinated with a live S. Enteritidis vaccine. For full details of the study see the poster presented at the
13S International Symposium Salmonella and Salmonellosis, 10-12 May 2006, St Malo, France.
