Properties of Arenaviridae

The family Arenaviridae derives its name from the presence within virions of cellular ribosomes, which in electron micrographs resemble grains of sand (arena, sand), and are incorporated into virions coinciden tally during budding (Table 32-2). Arenaviruses are pleomorphic, 110-130 nm (rarely up to 300 nm) in diameter (Fig. 32-1), and are composed of a lipoprotein envelope covered with glycoprotein peplomers surrounding two circular nucleocapsid seg-
