Most infected birds of species that belonged to the orders Anseriformes
, Falconiformes, and Strigiformes were found dead, but a few infections were detected in swab specimens from healthy mallards and feces of wild birds.
Bar-headed geese, whooper swans, and other anseriforme
birds in Mongolia were infected with QH09-like clade 2.
Multiple cases were found in Ciconiiformes (n = 4), Columbiformes (n = 4), Gruiformes (n = 4), Anseriformes
(n = 3), Galliformes (n = 3), and Passeriformes (n = 2).
Wild aquatic birds of the orders Anseriformes
and Charadriiformes are the natural reservoir for influenza A viruses (1) and are thought to serve as a source of virus that leads to outbreaks in domestic poultry.
, represented in PTWRC by only 4 birds (Anas poecilorhyncha), did not show any clinical signs.
25) In psittacine bird species, the osmolar gap has the same theoretical use as in mammals for diagnosing certain toxicoses, but the occurrence of these types of toxicoses in pet birds (eg, ethylene glycol, methanol, paraldehyde) is rare and largely unreported, except in anseriformes
The primary reservoirs of avian influenza (AI) are wild birds in the orders Anseriformes
(ducks, geese, and swans) and Charadriiformes (gulls, terns, and shorebirds).
The majority of positive samples, detected by both assays, were from species that use aquatic habitats, with the highest prevalence from species in the orders Anseriformes
A smaller portion than expected were Anseriformes
Most of these HPAI (H5N1) isolates were recovered from a limited number of species in the order Anseriformes
, including mute swans (Cygnus olor), whooper swans (C.
30 x PCV provides a reasonable estimate of Hgb concentration from the PCV of birds from the orders Anseriformes
, Columbiformes, Falconiformes, Galliformes, Passeriformes, Psittaciformes, Sphenisciformes, and Strigiformes, but a separate relationship of Hgb = 0.
Wild aquatic birds belonging to the orders Anseriformes
and Charadriiformes have long been recognized as the natural reservoirs for all influenza type A viruses (1).
All identified AIV-positive hosts (n = 35) were members of the order Anseriformes
Since 2002, HPAI (H5N1) has been reportedly isolated from >50 different wild avian species, mainly aquatic birds in the order Anseriformes
