“…The lower level of antibody detection (less than 50%) to APMV-4 and APMV-8 in some states cannot be explained, but these prevalence estimates are based on only one or two sampling locations per state and differences may reflect local spatial variation. In Canada geese, significant variation of IAV antibody prevalence has been reported at sample locations within 10 km of each other (Kistler et al, 2012). Only low prevalence estimates of NDV antibodies in North American waterfowl (less than 16%) have previously been reported (Kocan et al, 1979;Vickers & Hanson, 1982), and to our knowledge, there have been no reports of testing for antibodies to other APMVs in North American waterfowl.…”

“…These results are supported by the very low antibody prevalence we observed across a very broad geographical area, including northern latitudes where IAVs are more likely to be detected in waterfowl . As a comparison, antibody prevalence in mallards (Anas platyrhynchos) and Canada geese (Branta canadensis) sampled during these same time periods can exceed 50% and 20%, respectively (Brown et al, 2010;Kistler et al, 2012). Although, the duration of the detectable IAV antibody response is not well defined for wood ducks, and may partially explain the low prevalence, antibodies to IAV nucleoprotein have been detected for more than 1 year in naturally exposed mallards (Fereidouni et al, 2010) and for 21 days in experimentally infected wood ducks and mallards (Costa et al, 2011).…”

Wood ducks (Aix sponsa) as potential reservoirs for avian influenza and avian paramyxoviruses

Influenza A viruses (IAVs) and avian paramyxoviruses (APMVs) are important pathogens of poultry worldwide, and both commonly occur in wild waterfowl, especially ducks in the family Anatidae. Although wood ducks (Aix sponsa) are members of the Anatidae, their behaviour differs from most other species in this family, which could affect the transmission of IAVs and APMVs. We collected cloacal and oropharyngeal swab and blood samples from more than 700 wood ducks across nine states in the eastern United States of America. No IAVs were isolated, and based on blocking enzyme-linked immunoassay ELISA results, antibodies to IAVs were only detected in 0.2% of samples. In contrast, 23 (3%) APMVs were isolated (22 Newcastle disease virus and 1 APMV-6), and antibodies to multiple serotypes of APMVs were detected in more than 60% of the samples. After-hatch-year birds were more likely to be antibody positive for APMV-4 and APMV-6 compared to hatch-year birds. Female birds were more likely to be antibody positive for APMV-4 than were male birds. Our results indicate that wood ducks are probably not an important host for IAV but are frequently infected with APMVs.

“…We also included Canada goose samples collected in 2009 during a previous study (Kistler et al, 2012). These 2009 samples had antibodies to IAV NP as determined by the bELISA and were from New Jersey (n=63), Minnesota (n=14), Pennsylvania (n=134), and Washington (n=26).…”

“…summer molting) or in species where information about their role in the maintenance of IAVs is limited. Serology has been recently used to supplement virus isolation data and advance our current understanding of IAVs in Canada geese ( Branta canadensis ) (Kistler et al, 2012). …”

“…This perceived low prevalence of viral isolation is likely due to brief and infrequent viral shedding patterns reported in experimentally infected Canada geese (Berhane et al, 2014; Pasick et al, 2007) and sample timing which often occurred during a 3–4-week flight-less molting period during June and early July (Harris et al, 2010). Using serologic testing, Canada geese were found to be frequently exposed to IAVs and the prevalence of antibodies increased with latitude (Kistler et al, 2012). This increase in antibody prevalence in geese followed a similar trend of virus shedding data in dabbling ducks (Hinshaw et al, 1985; Stallknecht et al, 1990).…”

Historically, surveillance for influenza A viruses (IAVs) in wild birds has relied on viral detection assays. This was largely due to poor performance of serological assays in wild birds; however, recently developed commercial serological assays have improved the ability to detect IAV antibodies in wild birds. Serological surveillance for IAV antibodies in Canada geese (Branta canadensis) has shown that, despite a low prevalence of virus isolations, Canada geese are frequently exposed to IAVs and that exposure increases with latitude, which follows virus isolation prevalence patterns observed in dabbling ducks. The objectives of this study were to further evaluate IAV antibodies in Canada geese using a subtype-specific serological assay to determine if Canada geese are exposed to subtypes that commonly circulate in dabbling ducks. We collected serum samples from Canada geese in Minnesota, New Jersey, Pennsylvania, and Wisconsin and tested for antibodies to IAVs using a blocking ELISA. Positive samples were further tested by hemagglutination inhibition for 10 hemagglutinin IAV subtypes (H1–H10). Overall, we detected antibodies to NP in 24% (714/2,919) of geese. Antibodies to H3, H4, H5, and H6 subtypes predominated, with H5 being detected most frequently. A decrease in H5 HI antibody prevalence and titers was observed from 2009 to 2012. We also detected similar exposure pattern in Canada geese from New Jersey, Minnesota, Washington and Wisconsin. Based on the published literature, H3, H4, and H6 viruses are the most commonly reported IAVs from dabbling ducks. These results indicate that Canada geese also are frequently exposed to viruses of the same HA subtypes; however, the high prevalence of antibodies to H5 viruses was not expected as H5 IAVs are generally not well represented in reported isolates from ducks.
