Figure 5From: Vaccination with attenuated Salmonella enterica Dublin expressing E coli O157:H7 outer membrane protein Intimin induces transient reduction of fecal shedding of E coliO157:H7 in cattleMucosal (fecal) IgA antibody response. Intimin-specific fecal IgA antibody concentrations were measured by ELISA. The bar graph depicts the mean (± standard deviation) of calves in each group. Normalization of data was performed by subtracting the OD410 of diluent-only wells from experimental values.Back to article page
