Figure 5

Comparison of HI titres measured against porcine avian-derived H1N1 isolate A/swine/Germany/R248/2010 and S/P ratios obtained by indirect ELISA using recombinant HA1 antigen of avian-derived H1N1 isolate A/swine/Germany/R1738/2011. Black dots – congruent qualitative result; white dots – incongruent qualitative result; HI titre shown as log2 series (starting dilution 1 = 1:10); dotted lines represent cut-off values.
