17. Paramyxoviridae and Pneumoviridae

Question 1

Which 2 viruses have the following properties:

Virions are enveloped, pleomorphic (spherical and filamentous forms occur), and 150-300 nm in diameter. They are covered with large spikes (8-14 nm in length) or 13 nm (family 2) in diameter

Virions contain a “herringbone-shaped” helically symmetrical nucleocapsid, 600-800 nm in length, and 18 nm (family 1).

Virion envelope contains two or three viral glycoproteins and one or two nonglycosylated proteins.

Genome consists of a single linear molecule of negative-sense, single-stranded RNA, 13-19 kb in size, with seven to eight open reading frames encoding 10-12 proteins, including NP (or N), P, M, F, L, and HN (or H or G), which are common to all genera.

Cytoplasmic replication, budding from the plasma membrane. Syncytium formation, intracytoplasmic and intranuclear inclusion bodies (genus X)
