Abstract
Multiple antigenic peptides (MAPs) that included the common antigenic epitopes of porins from the outer membranes (OM) of bacteria from the Yersinia genus (Y. pseudotuberculosis, Y. enterocolitica, and Y. pestis that are pathogenic for humans) were synthesized. Mice of the BALB/c line were immunized with these peptides, and antisera to the peptides were obtained. It was demonstrated by EIA that these sera interacted with the porins that were isolated from the OM of pathogenic Yersinia. MAPs were shown to be bound to the antibodies in the blood sera of rabbits immunized with the individual porins and to the antibodies in the blood sera of humans suffering from intestinal yersiniosis and pseudotuberculosis.
