Different-sized Infective Particles of Rift Valley Fever Virus

Abstract

IN a recent communication, Polson1 indicated that the small animal viruses fall into definite weight-groups as calculated from their sedimentation constants, using the usual assumptions regarding density and particle shape. The particle weights are multiples of 1, 4, 16 and 64 of a basic unit, 12 mµ in diameter. Soluble antigen which itself is non-infective has been recovered from tissues infected with a variety of virus. It is of particular interest that those soluble antigens which have been measured are all approximately 12 mµ in diameter (influenza2, rabies3 and African horsesickness virus4).
