Virions of AFV3 are flexuous filaments, about 2000 nm in length and 24 nm in width. They are enveloped with a 3,1 nm thick envelope which can be removed by treatment with detergents. At the two ends of virions are present complex collars with two sets of filaments, resembling a bottle brush with a cap 17 nm in diameter on its top. Scale bars, A, 200 nm; the rest, 100 nm.
