SALMONELLA DUBLIN SRP®
SALMONELLA DUBLIN SRP®
An autogenous Salmonella Dublin vaccine with SRP technology is an excellent tool.
Salmonella Dublin is a common cause of calf illness, with high morbidity and mortality rates in affected animals, and is endemic in many regions of the U.S. and Canadian dairy industries.1-3 A 2016 report from the U.S. National Veterinary Services Laboratory found that S. Dublin was the most isolated Salmonella serotype obtained from ill cattle in the U.S. This serotype is also considered to be host adapted in bovine. Therefore, carrier animals that appear normal can be intermittent shedders and a source for maintaining the infection within a herd.3
