Type Species

Respirovirus is a genus of viruses in the order Mononegavirales, in the family Paramyxoviridae, in the subfamily Paramyxovirinae. Rodents and human serve as natural hosts. There are currently five species in this genus including the type species Sendai virus. Diseases associated with this genus include: acute febrile respiratory tract infection.[1][2]

Life Cycle

Viral replication is cytoplasmic. Entry into the host cell is achieved by virus attaches to host cell. Replication follows the negative stranded RNA virus replication model. Negative stranded RNA virus transcription, using polymerase stuttering is the method of transcription. Translation takes place by leaky scanning, and ribosomal shunting. The virus exits the host cell by budding. Rodents and human serve as the natural host. Transmission routes are respiratory.[1]
