Subfamily: Orthoparamyxovirinae

Genus: Jeilongvirus

Distinguishing features

These viruses contain two extra transcription units between the fusion (F) and receptor binding protein RBP genes encoding membrane associated proteins, with exception of Mount Mabu Lophuromys virus 1 (MMLV-1) and Mount Mabu Lophuromys virus 2 (MMLV-2) which contain only a single small trans-membrane protein. All members encode a non-structural protein (C). The viruses have mostly been isolated from rodents (Li et al., 2006).

Species demarcation criteria

Species demarcation is now entirely based on the distance in the phylogenic tree based on the comparison of complete large (L) protein amino acid sequences. Since the primary criterion is the tree topology, whether a virus belongs to the same species becomes a matter of branch length between the nearest node and the tip of the branch. This length is defined as 0.03 in the trees generated as described in the legend to Figure 3. .Paramyxoviridae.
