Geometric mean serum antibody titers in newborn mice before and after an i.n. challenge with C. trachomatis MoPn at 2 PND

Newborn mice born from and fed by:	PND	Anti-C. trachomatis MoPn ELISA titer
		IgG	IgG1	IgG2a	IgG2b	IgG3	IgA	IgM
Immunized-dams	0	10,159	400	5,080	6,400	1,600	504	<100
	7	32,254	5,080	51,200	25,600	3,200	4,032	<100
	18	32,254	5,080	81,275	16,127	2,540	4,032	100
Sham-immunized-dams	0	<100	<100	<100	<100	<100	<100	<100
	7	<100	<100	<100	<100	<100	<100	<100
	18	673	<100	126	238	566	168	100

^aGeometric mean titers were obtained from pooled serum samples of newborn mice collected from three separate experiments.
