Virus Properties by Family

 

Columns in the table with blue text headers can be sorted by clicking on the header text. Clicking twice will reverse the sort order.

Family
This column lists the virus families that are recognized in the current Master Species List (MSL).

Genome composition
This column describes the chemical nature of the genome (DNA or RNA) and whether it is double-stranded (ds) or single stranded (ss). The suffix -RT indicates that reverse transcription is involved in the replication of the genome.

For ss genomes, the polarity of the genome is indicated: (+), mRNA polarity; (-), complementary to mRNA; (+/-), ambisense. At the family level, viruses with segmented genomes may have segments with different polarities (e.g., some arenaviruses have only ssRNA(-), others have ssRNA(-) and ssRNA(+/-) segments. In this case, the genome composition is designated as ssRNA(-); ssRNA(+/-) to indicate that both forms can be found in the genome.

Genome organization
This column indicates if the genome is a linear or circular molecule and the number of segments

Total genome size (kb or kbp)
This column indicates the range of sizes encompassed by genomes of virus isolates described in the current Virus Metadata Resource (VMR).

Envelope?
This column indicates if the virion is known to have, or not have, a lipid envelope. A value of "Yes or No" indicates the variable presence of an envelope. Viruses identified only by metagenomics will usually not have a value in this column (envelope is "not determined").

Virion shape
This column indicates the shape of the virion, as seen by electron microscopy. The column also includes some predicted morphologies but does not include information for many viruses identified only by metagenomics.

Virion size
This column indicates the range of virion sizes encompassed by virus isolates described in the current VMR.

Host
This column indicates the known host(s) of viruses in the family. Hosts are uncertain for many viruses, especially those described by metagenomic analysis of environmental samples. The term protist is used to mean any eukaryotic organism that is not an animal, plant or fungus.
