The agglutination activities of the WT and MA-P5 viruses in three types of chicken red blood cells (cRBCs) and sheep red blood cells (sRBCs) were determined by HA titer. cRBCs, cRBCs with α-2,3-linked sialic acid receptors and α-2,6-linked sialic acid receptors; α-2,3 cRBCs, cRBCs treated with α-2,3-sialidase (with only α-2,6-linked sialic acid receptors); α-2,6 sRBCs, sRBCs (with only α-2,3-linked sialic acid receptors); and desialylated (desial) cRBCs, cRBCs treated with VCNA (no receptors). The values are shown as the means and standard deviations of three independent experiments. *P < 0.05 (MA-P5 vs WT).
