Characterization of the translational defect to fiber synthesis in monkey cells abortively infected
with human adenovirus: Role of ancillary leaders
The closest human adenoviral relatives were the species D adenoviruses, which share 54.3 % to 55.1 % identity to TMAdV,
with human adenoviruses of other species slightly less similar (51.1 % — 54.6 %).

Furthermore, severe infections from

The decreased levels of neutralizing Abs to TMAdV in the researcher (1 ∶ 32) and a family member (1 ∶ 8) relative to those in infected titi monkeys (up to > 1 ∶ 512) are consistent
with a recent study showing much higher levels of neutralizing antibodies in chimpanzees than in
humans with adenovirus infections, possibly due to more robust
adenovirus - specific T - cell responses in
humans than in monkeys [45].
These viruses do not circulate in the
