identification and characterization of avihepadnaviruses isolated from exotic anseriformes maintained in captivity.five new hepadnaviruses were cloned from exotic ducks and geese, including the chiloe wigeon, mandarin duck, puna teal, orinoco sheldgoose, and ashy-headed sheldgoose. sequence comparisons revealed that all but the mandarin duck viruses were closely related to existing isolates of duck hepatitis b virus (dhbv), while mandarin duck virus clones were closely related to ross goose hepatitis b virus. nonetheless, the s protein, core protein, and functional domains of the pol protein were highly cons ...200515708992
experimental infection with low and high pathogenicity h7n3 chilean avian influenza viruses in chiloe wigeon (anas sibilatrix) and cinnamon teal (anas cyanoptera).two different wild duck species common in chile and neighboring countries, chiloe wigeon (anas sibilatrix) and cinnamon teal (anas cyanoptera), were intranasally inoculated with 10(6) mean embryo infective dose (eid50) of the h7n3 low pathogenicity (lp) avian influenza virus (aiv) (a/chicken/chile/176822/02) or high pathogenicity (hp) aiv (a/chicken/chile/ 184240-1/02), in order to study the infectivity and pathobiology of these viruses. none of the virus-inoculated ducks had clinical signs or d ...201122017047
haemosporidian parasites of chilean ducks: the importance of biogeography and nonpasserine hosts.biogeography is known to have shaped the diversity and evolutionary history of avian haemosporidian parasites across the neotropics. however, a paucity of information exists for the temperate neotropics and especially from nonpasserine hosts. to understand the effect of biogeography in the temperate neotropics on haemosporidians of nonpasserine hosts we screened ducks (anseriformes) from central chile for the presence of these parasites. forty-two individuals of 4 duck species (anas flavirostris ...202032164026
