Applicability of anatid
and galliform microsatellite markers to the genetic diversity studies of domestic geese (Anser anser domesticus) through the genotyping of the endangered zatorska breed.
RT-PCR was optimized by using the following controls, including nucleic acids extracted from theca folliculi of healthy Pekin ducks: avian influenza virus, Newcastle disease virus, egg drop syndrome virus, anatid
herpesvirus 1, Muscovy duck parvovirus, goose parvovirus, duck reovirus, goose reovirus, duck hepatitis A virus, duck astrovirus, duck circovirus, and goose hemorrhagic polyomavirus.
However, in our study area, second broods are very rare as are replacement clutches, because the breeding season is short and anatid
males leave the breeding sites early.

The epizootiology of anatid
herpesvirus 1 infection in waterfowl is poorly understood but apparently involves persistence of the virus in latently infected birds.
Other characteristics of the mallard support its potential role as a vector (, online Appendix Figure 1): it is the most abundant anatid
species in Western Eurasia ([approximately equal to] 9 million birds); part of the population migrates long distances northeast to southwest between breeding and wintering areas; and it is found on nearly every type of wetland and is very tolerant of human presence, thus forming a potential link between wild waterfowl, domestic animals, and humans.
One could also mention here the discrepancies between the geographic spread of HPAI H5N1 virus and overall pattern of wild bird migrations: the virus has never been reported in the Philippines and in several countries farther south such as New Zealand and Australia (although these 2 countries have no migratory anatid
populations connecting them to Southeast Asia, they do have many shore bird and wader species in common ).
Of bird bones, the numerous representatives of anatids
(Anatidae) were accompanied by the more unusual findings of cormorant (Phalacrocorax carbo) and white-tailed eagle (Haliaeetus albicilla).
