[The common antigenic determinants of the H antigens of salmonellae]

Salmonella H-antigens have common and specific antigenic determinants. Studies on the determination of common antigenic determinants of H-antigens (a; b; d; i; 1,2 and nt) has been carried out. The order of the distribution of H-antigens according to the decrease of these common antigenic determinants in size is presented: d greater than a greater than 1,2 greater than b greater than nt. These data broaden our knowledge of the structure of H-antigens; they are also necessary for obtaining specific antibodies and conjugate preparations used in the enzyme immunoassay.
