Salmonella serotyping by the coagglutination method using protein A rich Staphylococcus sensitized with specific antibody.

This paper outlines a more economical method in the serological identification of salmonella by using protein-A rich staphylococci sensitized with Salmonella polyvalent 0 and H antisera. Preliminary studies show that this method is simple, economical and as sensitive and specific as the original commercially prepared antisera with the exception of Salmonella typhi where there appears to be some loss of sensitivity with these strains.
