Figure 2From: H5-based DNA constructs derived from selected highly pathogenic H5N1 avian influenza virus induce high levels of humoral antibodies in Muscovy ducks against low pathogenic virusesCompared serological responses in HI tests, following immunization with different H5 optimized DNA constructs. HI tests were performed against LP H5N1 A/duck/France/05066b/2005 and LP H5N3 A/Muscovy duck/France/070090b/2007 [20, 21]: see Figure 1 for legend. NS indicates overall non statistically significant differences between groups.Back to article page
