Taxonomy of viruses
From WikiLectures
The taxonomy of viruses is based on the division according to the nucleic acid, whether it is single- or double-stranded or the polarity of the strands. Other features are the presence of the envelope, the shape (or symmetry) of the virion. The taxonomy is constantly being refined and changed. There are only medically important genera and species in the scheme.
DNA viruses
| Nucleic acid | Type of strand | cover | figure | Representatives |
|---|---|---|---|---|
| DNA | ss (single strand) | yes | does not exist | |
| DNA | ss | without cover | icosahedral | Parvovirus |
| DNA | ds (double strand) | yes | icosahedral | Herpesviridae (HSV,VZV, CMV, EBV...) |
| DNA | ds | yes | icosahedral | Hepadnaviridae (Hepatitis B vir.) |
| DNA | ds | yes | complex | Poxviridae (smallpox virus) |
| DNA | ds | without cover | icosahedral | Adenovirus |
| DNA | ds | without cover | icosahedral | Papovaviridae (papiloma virus) |
RNA viruses
| Nucleic acid | Thread and polarity | cover | figure | Representatives |
|---|---|---|---|---|
| RNA | ss | without cover | icosahedral | Picornaviridae (Entero and Rhinovirus) |
| RNA | ss (-) | yes | helical | Myxovirus (Influenza) |
| RNA | ss (-) | yes | helical | Paramyxovirus (parainfluenza, measles ) |
| RNA | ss (+) | yes | icosahedral | Togaviridae (e.g. rubella virus) |
| RNA | ss (+) | yes | icosahedral | Flavivirus (yellow fever, tick. Encephalitis, etc.) |
| RNA | ss (+) | yes | icosahedral | Retroviridae (virus HIV) |
| RNA | ss | yes | helical | Rhabdoviridae (rabies virus) |
| RNA | ss | yes | helical | Filiviridae (Ebola) |
| RNA | ss | yes | helical | Arenaviridae (Lassa, LCM) |
| RNA | ss (+) | yes | helical | Coronavirus |
| RNA | ds | without cover | icosahedral | REOviridae (Rotavirus) |
