Use of an attenuated live Salmonella Typhimurium vaccine on three breeding pig units: A longitudinal observational field study

Highlights • Parenteral administration of a live Salmonella Typhimurium vaccine to dams in the context of commercial breeder or breeder-finisher units was associated with rapid control of clinical salmonellosis. • Over one to two years, sustained reductions in the shedding of Salmonella Typhimurium,...

Description
Summary:Highlights • Parenteral administration of a live Salmonella Typhimurium vaccine to dams in the context of commercial breeder or breeder-finisher units was associated with rapid control of clinical salmonellosis. • Over one to two years, sustained reductions in the shedding of Salmonella Typhimurium, and a closely-related monophasic variant, were observed. • The maternal vaccination was associated with improved Salmonella status in all age groups. • Evidence for control of other (non-Typhimurium) Salmonella serovars was not seen.
