Morbillivirus is a genus of viruses in the order Mononegavirales, in the family Paramyxoviridae, in the subfamily Paramyxovirinae. Human, dog, cattle, and cetacean serve as natural hosts. There are currently six species in this genus, including the type species Measles virus. Diseases associated with this genus include: measles: fever, rash; animal: acute febrile respiratory tract infection.[1][2]

Structure

Viruses in Morbillivirus are enveloped, with spherical geometries. The diameter is around 150 nm. Genomes are linear, around 15-16kb in length. The genome codes for 8 proteins.[1]

Life Cycle

Viral replication is cytoplasmic. Entry into the host cell is achieved by virus attaching to host cell. Replication follows the negative stranded RNA virus replication model. Negative stranded RNA virus transcription, using polymerase stuttering, through co-transcriptional RNA editing is the method of transcription. Translation takes place by leaky scanning. The virus exits the host cell by budding. Human, dog, cattle, and cetacean serve as the natural host. Transmission routes are respiratory.[1]
