... viruses viruses that have envelopes surrounding their nucleocapsids. Each viral envelope is derived from the host cell, and as a result the viruses will contain lipids as well as nucleic acids and proteins. Spikes often project from the envelopes, and these contain virus-encoded proteins. The corona viruses, herpes viruses, HIVs, influenza viruses, Sendai viruses, and smallpox viruses are examples of viruses with...

Sendai virus

Sendai virus  

A virus, first isolated in Japan, that causes an important and widespread infection of laboratory mice; it belongs to the Paramyxoviridae. The virus is widely used in cell fusion studies. The viruses ...
Sindbis virus

Sindbis virus  

Reference type:
Overview Page
An enveloped virus of the alphavirus group of Togaviridae. It is not thought to be infectious in humans and has been extensively used as a model system in which to study the synthesis and export of ...
coronavirus

coronavirus  

A family of viruses that have a positive-strand RNA genome and are characterized by a viral envelope from which petal-shaped spikes protrude. The virus causing severe acute respiratory syndrome ...
Orthomyxoviridae

Orthomyxoviridae  

Reference type:
Overview Page
The class V viruses, mostly influenza viruses. Their genome is a negative strand of RNA present as several separate segments, each a template for a single mRNA synthesized by a virus-specific RNA ...
Papillomaviridae

Papillomaviridae  

Reference type:
Overview Page
A family of double-stranded DNA viruses that infect vertebrates and cause benign epithelial tumours (e.g. warts). They are not enveloped and are isometric (the virions have icosahedral ...

respiratory syncytial virus  

Reference type:
Overview Page
An enveloped RNA virus of the parainfluenza family, responsible for coughs and colds in the winter period.
peplomers

peplomers  

Spikes that protrude from the envelopes of certain viruses. For example, the rabies virus (q.v.) has about 400 peplomers dispersed evenly over its surface, except for its planar end. Each spike ...
foot and mouth disease virus

foot and mouth disease virus  

The seven serotypes of foot‐and‐mouth disease (FMD) virus, together with equine rhinovirus 1 form the aphthovirus genus of the family Picornaviridae. The virion is non‐enveloped, 25–30 nm in ...
Semliki forest virus

Semliki forest virus  

Reference type:
Overview Page
An alphavirus of the Togaviridae family. It has a positive-stranded RNA genome and an icosahedral capsid enveloped by a host-cell derived lipid bilayer and has been extensively used as a model system ...
Coronaviridae

Coronaviridae  

Reference type:
Overview Page
A family of enveloped, single-stranded, positive-sense RNA viruses with club-shaped projections radiating outwards that give a charateristic corona appearance to negatively stained virions. They are ...
