Par·a·myx·o·vir·i·dae

(par'ă-mik'sō-vir'i-dē),
A family of RNA-containing viruses about twice the size of the influenza viruses (Orthomyxoviridae) but similar to them in morphology. Virions are 150-300 nm in diameter, enveloped, ether sensitive, and contain RNA-dependent RNA polymerase. Nucleocapsids are helical, considerably larger than those of the influenza viruses, and contain single-stranded unsegmented RNA. Four genera are recognized: Paramyxovirus, Morbillivirus, Rubulavirus, and Pneumovirus, all of which cause cell fusion and produce cytoplasmic eosinophilic inclusions. Diseases associated with these viruses include croup and other upper respiratory infections, measles, mumps, and pneumonia.

Paramyxoviridae

/Para·myxo·vi·ri·dae/ (-mik″so-vir´ĭ-de) the paramyxoviruses; a family of RNA viruses with a single-stranded, negative-sense RNA genome, including two subfamilies, Paramyxovirinae and Pneumovirinae.

Paramyxoviridae

a family of viruses in the order Mononegavirales containing two subfamilies, Paramyxovirinae and Pneumovirinae.Paramyxovirinae comprises five genera: Respirovirus, which includes paramyxoviruses of humans, cattle, dogs and various avian species (avian paramyxoviruses 2-9); Morbillivirus, which includes measles, canine distemper, and rinderpest; Rubulavirus, which includes mumps and a pig rubulavirus; Henipavirus, which includes Hendra and Nipah viruses; Avulavirus, which includes Newcastle disease virus. Pneumovirinae comprises the genera Pneumovirus, which includes respiratory syncytial viruses of humans, cattle, sheep and cats, and the genus Metapneumovirus, which includes turkey rhinotracheitis virus. Viruses in the family are large (180 nm diameter) enveloped and contain a genome that is a single molecule of single-stranded negative sense RNA.
