For active immunisation of chickens against Salmonella Enteritidis and Salmonella Typhimurium.

The live vaccine strain stimulates cell-mediated immunological mechanisms (as demonstrated in mice) and antibody formation in chickens against Salmonella Enteritidis and Salmonella Typhimurium. The antibody formation does not affect serological testing for Salmonella Gallinarum (rapid serum agglutination).

The vaccine strain is resistant to sulfamerazine. The strain has been demonstrated as genetically stable.
