VNA response in Swiss Webster mice after intradermal infection with CVS-N2c or CVS-B2c

Days after infection*	Titer		Significance
	CVS-N2c	CVS-B2c
5	66.0 ± 18.3	102.0 ± 23.3	0.241
6	95.0 ± 20.3	166.0 ± 33.0	0.083
7	141.0 ± 50.6	414.0 ± 88.2	0.015
8	207.0 ± 46.6	738.0 ± 269.9	0.068
9	108.0 ± 28.0	837.0 ± 248.9	0.009
10	90.0 ± 24.0	747.0 ± 235.5	0.018

Data are the mean ± SEM of the reciprocal titers (reciprocal of the highest dilution of serum yield as a 50% reduction in test virus, as determined by the fluorescent focus inhibition test) for a group of 10 mice. The significance was determined by using the unpaired t test. 

^*Mice were infected with 10⁴ FFU of CVS-N2c or CVS-B2c.
