DESCRIPTION OF VIRUSES

Family Parvoviridae

Genus Brevidensovirus

Genus Brevidensovirus

Type Species

Aedes aegypti densovirus

(AaDNV)

Distinguishing Features

The genome is about 4  kb in size. Populations of virions encapsidate positive and negative strands, a majority of which are of negative polarity (85%). ORFs for the structural and NS proteins are on the same strand. There are mRNA promoters at map units 7 and 60. There is a small ORF of unknown function on the complementary strand. A palindromic sequence of 146  nts is found at the 3-end of the genome and a different palindromic sequence of 164  nts at the 5-end. Both terminal sequences can fold to form a T-shaped structure.
