Table 2. Summary of the homologous (Ig (G+M), IgG1, IgG (2a+2b), IgA) and heterologous (Ig (G+M)) antibody responses after the last immunization with SipD or IpaD by the IN and IG routes.

	Homologous antibody response					Heterologous response
Immunization route	Immunogen	Ig(G+M)	IgG1	IgG(2a+2b)	IgA titer	Ig (G+M)
IN	SipD	1.7 x 103	2.6 x 103	4.6 x 102	2.4 x 102	4.4 x 101
	IpaD	2.9 x 104	2.0 x 104	6.8 x 103	5.2 x 102	2.9 x 101
IG	SipD	1.2 x 103	6.8 x 103	9.9 x 102	1.7 x 102	4.4 x 100
	IpaD	2.6 x 104	4.9 x 102	8.3 x 103	3.8 x 102	1.9 x 102

Data represent mean concentrations (ng/mL) for Ig(G+M), IgG1, IgG(2a+2b) responses and IgA titer from each group of mice.
