MOESM3 of Streptococcus suis cps7: an emerging virulent sequence type (ST29) shows a distinct, IgM-determined pattern of bacterial survival in blood of piglets during the early adaptive immune response after weaning

Additional file 3. IgM titers in the sera of the investigated 6.5 week old cps7 free piglets against cps7 strain 13-00283-02 are substantially reduced after preabsorption with strain 10cpsΔEF. IgM antibody titers of the 5 piglets investigated for the data presented in Figure 5 were also determined after absorption of the sera with the unencapsulated cps2 mutant strain 10cps∆EF. Means and standard deviations are indicated by horizontal lines and error bars, respectively. Each symbol represents a different animal. Differences were not significant using a two-tailed paired t-test.
