*Samples were from adult guinea pigs raised as livestock on local farms (Cuenca) or from live animal markets (Guayaquil and Manabí). H1, recombinant hemagglutinin from A/California/04/2009 (Cal09); H3, recombinant hemagglutinin from A/Wisconsin/67/2005; H5, recombinant hemagglutinin from A/Vietnam/1203/2004 (Vietnam04); NP, recombinant nucleoprotein from A/Brisbane/10/2007; N1, recombinant neuraminidase from Cal09 or Vietnam04; N2, recombinant neuraminidase from A/Hong Kong/1/1968.
†Serum samples were considered positive if absorbance (read at 405 nm) was higher than the value of the negative control (naive guinea pig serum) +3 SD.
‡Only 14 samples were tested.
§Only 9 samples were tested.
