First molecular evidence for the existence of distinct fish and snake adenoviruses

Mária Benkó et al. J Virol. 2002 Oct.

Abstract

From adenovirus-like viruses originating from a fish and a snake species, a conserved part of the adenoviral DNA polymerase gene was PCR amplified, cloned and sequenced. Phylogenetic analysis showed that the snake adenovirus is closely related to the members of the proposed genus Atadenovirus, whereas the fish isolate seems to represent a separate cluster, likely a new genus.

Figures

FIG. 1.
FIG. 1.
Alignment of the partial amino acid sequence of the DNA polymerase gene from 24 adenovirus types. Abbreviation of the adenovirus types is as follows (complemented with the serotype number where appropriate): B, bovine; C, canine; D, duck; F, fowl; fish, white sturgeon; Fr, frog; H, human; M, murine; O, ovine; P, porcine; Po, brushtail possum; snake, corn snake; T, turkey; and TS, tree shrew adenovirus. From each of the six human adenovirus species (A to F), only one representative serotype was included. Amino acid residues conserved in the members of at least two genera are printed in boldface. Regions applicable and selected for the phylogenetic analyses are boxed.
FIG. 2.
FIG. 2.
Phylogenetic tree calculated by distance matrix analysis. The total length of the edited alignment after removal of the obviously nonhomologous parts was 106 aa. Unrooted tree, the fish adenovirus was chosen as outgroup. Bootstrap values (from 100 data sets) show the high reliability of the tree topology regarding the clustering of the five proposed genera (printed in boldface).
