PSV-A-9 Reduction of Salmonella Reading Using a Dairy-Originated Probiotic Bacterium, Propionibacterium Freudenreichii in Combination with a Live Attenuated Salmonella Typhimurium Vaccine in Growing Turkeys

Toxicity of lipopolysaccharide and of soluble extracts of Salmonella typhimurium in mice immunized with a live attenuated aroA salmonella vaccine.

Mice immunized intravenously 10 days earlier (but not those immunized 2 months earlier) with an attenuated Salmonella typhimurium SL3261 aroA live vaccine and tested for delayed-type hypersensitivity by injection of crude Salmonella extracts in the footpad can die within 24 to 48 h of an unexplained allergic reaction. The lethal reaction could be prevented by prior administration of anti-tumor ...

Immunogenic potential of a Salmonella Typhimurium live vaccine for pigs against monophasic Salmonella Typhimurium DT 193

BACKGROUND Monophasic Salmonella Typhimurium (mSTM) strains account for up to 8.6% of all human Salmonellosis cases. They have an increasing prevalence during recent years and several human cases with hospitalisation were reported. These strains are often isolated from pigs and pork - one primary source of human infection. A Salmonella Typhimurium (STM) live vaccine has been proven successful i...

A review of prophylactic measure against brucellosis in human with a live attenuated vaccine

The production of an auxotrophic marked, plasmid-cured Salmonella ser. Typhimurium as a live attenuated vaccine.

A number of amino acid requiring auxotrophic strains of Salmonella Typhimurium were produced by chemical mutagenesis. One of them, strain 81, was cured of the virulence plasmid and attenuated for mice. This strain had an auxotrophic requirement for serine, which could be used as a marker for the differentiation of the vaccine strain from other isolates in the field. The strain still contained t...

Protection Against Salmonella Typhimurium, Salmonella Gallinarum, and Salmonella Enteritidis Infection in Layer Chickens Conferred by a Live Attenuated Salmonella Typhimurium Strain

In the present study, we investigated the protection conferred by a live attenuated Salmonella enterica serovar Typhimurium (ST) strain against Salmonella Typhimurium, Salmonella Gallinarum (SG), and Salmonella Enteritidis (SE) infection in layer chickens. Birds were orally primed with the attenuated ST strain at 7 days of age and then boosted at 4 weeks post prime immunization (PPI). Sequentia...
