The results of the present study show that whereas both BALB/c and C57BL/6 mice parenterally inoculated with a horse serum albumin-Escherichia coli O157 antigen conjugate vaccine develop systemic, specific antibodies to the carrier protein, only the former mice routinely develop antibodies to the carbohydrate O157 moiety. However, little convincing evidence was found to show that these antibodies transuded into the intestinal tract either naturally or in response to an oral inoculum of the… CONTINUE READING
