(TRTV) |
The relative placements of SH-G versus F-M2 in the gene order are reversed as compared to pneumoviruses. No NS1 and NS2 genes as found in pneumoviruses. Virions do not appear to contain a hemagglutinin or neuraminidase.

Unassigned Viruses in the Family
In addition to two recognized viruses, namely Fer-de-Lance virus of reptiles (FDLV), and the rodent Nariva virus (NARV), several viruses from penguins are known which are distinct from Avian paramyxoviruses 1-9. Furthermore, Hendra virus appears to be related to the subfamily Paramyxovirinae (cognate F, H, M, H and P/V/C genes) was isolated from fruitbats and from horses in Queensland, Australia. On two known occasions the horse virus has caused lethal infection of man.
Phylogenetic Relationships within the Family
The literature on the relationships of members of the Paramyxovirinae is consistent with the phylogeny (Fig. 3).
The member viruses of the family Paramyxoviridae have a similar strategy of gene expression and replication and gene order to those of other families in the order Mononegavirales, that is the families Rhabdoviridae and Filoviridae.
Meta: from Greek meta for “after”
Morbilli: from Latin morbillus, diminutive of morbus, “disease”.
Ortho: from Greek orthos “straight”.
Paramyxo: from Greek para, “by the side of”, and myxa “mucus”.
Pneumo: from Greek pneuma, “breath”.
Respiro: from Latin respirare, “respire, breath”.
Rubula: Rubula inflans - old name for mumps.
