Figure 7From: The protective effect of recombinant Lactococcus lactis oral vaccine on a Clostridium difficile-infected animal model Anti-toxin A (TcdA) IgG and IgA antibodies in serum and intestinal fluid of different groups of hamsters. The anti-TcdA IgA titer in serum of secreted-protein and membrane-anchored plasmid groups was higher than that of the control group (P < 0.05). There was no significant difference in anti-TcdA IgA titer of intestinal fluid among all groups.Back to article page
