[Use of an artificial antigen simulating the Salmonella O-determinant 4 for determining antibodies to Salmonella group B O-antigen in immunoenzyme analysis].

: The use of the artificial antigen abequosylmannoside copolymer with acrylamide in the enzyme immunoassay for the determination of antibodies in the sera of salmonellosis patients has enhanced the specificity of the serological diagnosis of group B salmonellosis in comparison with the use of the natural antiren, S. typhimurium lipopolysaccharide.
