Web1 hour ago · Multiple topotypes of FMDV are described in the literature as circulating in the region, with further evolution of virus diversity predicted. ... High genetic diversity at the antigenic site or near the antigenic site can also be driven by a high substitution rate, purifying selection (negative selection), and diversifying selection (positive ... WebAntigenic variants of foot-and-mouth disease virus (FMDV) were generated and frequently became dominant in clonal populations of FMDV (clone C-S8c1) grown in the absence of anti-FMDV antibodies. We have now passaged eight samples of the same FMDV clone in the presence of a limited amount of neutralizing polyclonal antibodies directed to the ...
