Comparison of bacteria with and without plasmid-encoded proteins as antigens for measurement of immunoglobulin M, G, and A antibodies to Yersinia enterocolitica by enzyme-linked immunosorbent assay.

摘要

Yersinia enterocolitica serovar O:3 bacteria with and without plasmid-encoded proteins were compared as antigens in an enzyme-linked immunosorbent assay. Good correlations between the two antigen preparations were obtained for immunoglobulin M (IgM), IgG, and IgA antibodies of patients with yersiniosis. For routine diagnostic purposes, these antigens are considered equal.
