The Big Picture Book of Viruses: Adenoviridae



Taxonomy: Description is on the taxonomic level of family. Taxon contains the following Genera: Mastadenovirus; Aviadenovirus.

Host: Taxon infects vertebrates.

Genome: Linear; double stranded; DNA. Genome monopartite. Total genome 30000-42000 nucleotides long. Guanine + cytosine ratio very variable and ranges between 48-61 %. Genome sequence has terminal repeated sequences; inverted terminal repetitions (ITR). Terminal repeats at the 3'-end 50-200 nucleotides long. 5' terminus has a genome-linked protein (VPg).

Morphology: Virions isometric; not enveloped. Nucleocapsids appear to be angular; 70-90 nm in diameter. Symmetry icosahedral. Surface capsomere arrangement obvious. 252 capsomeres per nucleocapsid (8-9 nm in diameter). Surface projections of nucleocapsid distinct; one or two filaments; restricted to (the 12 vertices of capsid, but often not detected in negative stains). Virions may occur together with a dependent virus; may provide helper functions to dependent virus.
