... among macaques (Manson 1989). These threadlike polymorphic viruses are highly variable in length apparently owing to concatemerization. However, the average length of an infectious virion appears to be 920 nm. The virions are 80 nm in diameter with a helical nucleocapsid, a membrane made of 10 nm projections, and host cell membrane. They contain a unique single-stranded molecule of noninfectious (negative sense ) RNA. The virus is composed of 7 polypeptides, a nucleoprotein, a glycoprotein, a ...
