Table 2 Antigenic relatedness of the reference strain and field isolates

Antigenic relatedness of the reference strain (A/Ck/México/1994) and low pathogenic Avian Influenza H5N2 viruses isolated between 2002 and 2008 tested by hemagglutination inhibition (HI) test. Official virus ID: A). A/Ck/México/1994; B). A/Ck/México/2002; C). A/Ck/México/2003; D). A/Ck/México/2005; E). A/Ck/México/2006; F). A/Ck/México/2007; G). A/Ck/México/2008. Geometric mean values for HI test using different antisera (A-G) and low pathogenic Avian Influenza H5N2 viruses isolated between 2002 and 2008. Statistical comparisons were made using ANOVA and Fisher's protected least significant difference test. Columns with different superscript are significantly different (P ≤ 0.05).
