The degree of manifestation of the virulent properties of Y. pseudotuberculosis strains was found to be directly related to the concentration of protein with a mol. wt. of 103 kD (invasin), localized in the outer membrane and necessary for the realization of the process of the penetration of the infective agent into eukaryotic cells. Antiserum to INV-2-BSA, an active synthetic fragment of invasin, capable of detecting one antigenic band with a mol. wt. of 103 kD, was used for the creation of a diagnostic enzyme immunoassay system. The new variant of the diagnostic system was shown to be highly effective in the diagnosis of the disease at an early period.
