*Samples were from adult guinea pigs raised as livestock on local farms (Cuenca) or from live animal markets (Guayaquil and Manabí). Whole virus, B/Yamagata/16/1988. Recombinant hemagglutinin was derived from B/Florida/04/2006; nucleoprotein was derived from B/Yamagata/16/1988.
†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 19 samples were tested.
