ecology of influenza virus in wild bird populations in central asia.the study provides the results of avian influenza virus surveillance in central asia during 2003-2009. we have analyzed 2604 samples from wild birds. these samples were collected in kazakhstan (279), mongolia (650), and russia (1675). isolated viruses from samples collected in mongolia (13 isolates) and in russia (4 isolates) were described. virological analysis has shown that six isolates belong to the h3n6 subtype and five isolates belong to the h4n6 subtype. two h1n1 influenza viruses, one h1 ...201222545553
shedding light on avian influenza h4n6 infection in mallards: modes of transmission and implications for surveillance.wild mallards (anas platyrhychos) are considered one of the primary reservoir species for avian influenza viruses (aiv). because aiv circulating in wild birds pose an indirect threat to agriculture and human health, understanding the ecology of aiv and developing risk assessments and surveillance systems for prevention of disease is critical.201020877466
surveillance of avian influenza viruses in northern pintails (anas acuta) in tohoku district, japan.among winter migratory waterfowl, northern pintails (anas acuta), in one of the largest flocks in tohoku district, northeast japan, were surveyed for influenza a viruses at five wintering sites in three prefectures, viz., aomori, akita, and miyagi. a total of 38 influenza a viruses were isolated from 2066 fecal samples collected during november 2006 through march 2007. the overall isolation rate was 1.84%. eleven different subtypes were isolated, including nine h5n2, seven h6n8, seven h10n1, fou ...200818459295
the isolation of influenza a viruses and paramyxoviruses from feral ducks in new zealand.tracheal and cloacal swabs from apparently healthy ducks, gulls, shearwaters and terns in new zealand were tested for myxoviruses by inoculation into embryonated eggs. seven influenza a viruses belonging to three antigenic subtypes (h4n6; h1n3; h11n3) and nine paramyxoviruses of two antigenic subtypes (pmv-1; pmv-4) were isolated from feral ducks. the occurrence of the same virus subtypes in birds, including ducks, in other countries suggests that they were introduced into new zealand by the imp ...19846497784
