“…Two novel pigeon AdVs, types 4 and 5, were also classified as siadenoviruses . Among the PsAdVs, PsAdV‐2 is especially pathogenic and has been described already from more than half a dozen of different psittacine species and cockatoo . Such a broad host range is a rare trait even among siadenoviruses.…”

“…Such a broad host range is a rare trait even among siadenoviruses. Gouldian finches, red‐billed fire finches, and red‐throated parrot finches were found shedding Gouldian finch AdV‐1, a long‐tailed finch that harbored a novel siadenovirus . Recently, PsAdV‐5 was reported from cockatiel with chronic liver disease and a novel siadenovirus from Pacific parrotlets .…”

Adenoviruses (AdVs) infect representatives of numerous species from almost every major vertebrate class, albeit their incidence shows great variability. AdVs infecting birds, reptiles, and bats are the most common and diverse, whereas only one AdV has been so far isolated both from fish and amphibians. The family Adenoviridae is divided into five genera, each corresponding to an independent evolutionary lineage that supposedly coevolved with its respective vertebrate hosts. Members of genera Mastadenovirus and Aviadenovirus seem to infect exclusively mammals and birds, respectively. The genus Ichtadenovirus includes the single known AdV from fish. The majority of AdVs in the genus Atadenovirus originated from squamate reptiles (lizards and snakes), but also certain mammalian and avian AdVs are classified within this genus. The genus Siadenovirus contains the only AdV isolated from frog, along with numerous avian AdVs. In turtles, members of a sixth AdV lineage have been discovered, pending official recognition as an independent genus. The most likely scenario for AdV evolution includes long‐term cospeciation with the hosts, as well as occasional switches between closely or, rarely, more distantly related hosts.

“…The tropical screech owl AdV was detected in one bird only, and clustered into genus Atadenovirus. Atadenoviruses are thought to have coevolved with squamate reptiles [47,48], but several bird species are also infected by atadenoviruses [17,23,49]. As this owl species is a bird of prey, it is equally possible that this virus had already adapted to this host and replicated in this bird, or that this virus is a foodborne contaminant.…”

“…The presence of AdVs is described in many species of vertebrate animals, including mammals, birds, reptiles, amphibians, and fish [10][11][12][13][14]. It is known that birds are common hosts for AdVs, a fact that has been mirrored by the large number of avian AdVs [15][16][17][18][19][20][21][22][23][24][25]. The host bird species often live in crowded flocks, and migrate large distances by flying, and this predisposes to a rapid viral dissemination in the environment.…”

Identification of two novel adenoviruses in smooth-billed ani and tropical screech owl

et al. 2020

Avian adenoviruses (AdVs) are a very diverse group of pathogens causing diseases in poultry and wild birds. Wild birds, endangered by habitat loss and habitat fragmentation in the tropical forests, are recognised to play a role in the transmission of various AdVs. In this study, two novel, hitherto unknown AdVs were described from faecal samples of smoothbilled ani and tropical screech owl. The former was classified into genus Aviadenovirus, the latter into genus Atadenovirus, and both viruses most probably represent new AdV species as well. These results show that there is very limited information about the biodiversity of AdVs in tropical wild birds, though viruses might have a major effect on the population of their hosts or endanger even domesticated animals. Surveys like this provide new insights into the diversity, evolution, host variety, and distribution of avian AdVs.
