Salmonella enterica is known for serotype variation; poultry flocks are often exposed to 3-5 serotypes or more, out of a group of 20-30 familiar strains. Serotypes such as Heidelberg, Kentucky, Enteritidis, Hadar, Senftenberg and Oranienberg offer very little hope for shared immunity by using conventional whole-cell bacterins. Common autogenous bacterins may contain 2-4 Salmonella serotypes, which results in tissue reactivity, causing local granulomas and sometimes hemorrhagic hepatopathy.
Autogenous SRP® bacterial extract technology offers a new way to approach Salmonella through the immune system. Starting with an isolate of any serotype from your own operation, we can make a purified SRP extract vaccine utilizing proteins which are conserved across all common Salmonella serotypes.
Autogenous SRP vaccines can be made in a variety of adjuvants, dose volumes, pathogen combinations, and routes of administration.
Autogenous vaccines carry no USDA approved label claims for efficacy; therefore use according to the recommendation of your poultry veterinarian.
