Abstract

Salmonella is a common cause of disease in animals and humans. Many Salmonella infections are asymptomatic and many dairy herds do not know that they have Salmonella present until clinical cases present. Lack of recognition of subclinical salmonellosis or asymptomatic Salmonella infection by practitioners and producers can lead to oversight in management decisions for the infected herd, allowing the propagation of the pathogen within the herd. A novel vaccine against siderophore receptors and porin proteins (SRP® technology) has been adapted for control of Salmonella Newport in cattle. Many dairy producers utilize this vaccine on a routine basis for control of salmonellosis. However, there are no peer-reviewed papers on the efficacy of SRP Salmonella Newport vaccine for controlling Salmonella, or what impact this vaccine has on the health and production of dairy cows.
