Abstract A novel highly pathogenic avian influenza virus belonging to the H5 clade 2.3.4.4 variant viruses was detected in North America late 2014. Motivated by identification of these domestic poultry Canada, an intensive study initiated conduct surveillance wild birds Pacific Flyway United States. total 4,729 hunter-harvested were sampled and 1.3% (n = 63). Three subtypes isolated from birds, H5N2, H5N8, H5N1, representing wholly Eurasian lineage H5N8 two reassortant viruses. Testing 150...
Avian influenza is a viral disease that primarily infects wild and domestic birds, but it also can be transmitted to variety of mammals. In 2006, the United States America Departments Agriculture Interior designed large-scale, interagency surveillance effort sought determine if highly pathogenic avian viruses were present in bird populations within America. This program, combined with Canadian Mexican programs, represented largest, coordinated wildlife program ever implemented. Here we...
Avian bornaviruses (ABV), identified in 2008, infect captive parrots and macaws worldwide. The natural reservoirs of these viruses are unknown. Reverse transcription-PCR (RT-PCR) was used to screen oropharyngeal/cloacal swab brain samples from wild Canada geese (Branta canadensis) for ABV. Approximately 2.9% were positive bornavirus sequences. Fifty-two percent 2 urban flocks also tested positive, isolates cultured duck embryo fibroblasts. Phylogenetic analyses placed goose an independent...
Abstract Influenza D virus (IDV) has been identified in domestic cattle, swine, camelid, and small ruminant populations across North America, Europe, Asia, South Africa. Our study investigated seroprevalence transmissibility of IDV feral swine. During 2012–2013, we evaluated swine 4 US states; 256 tested, 57 (19.1%) were seropositive. Among 96 archived influenza A virus–seropositive samples collected from 16 states during 2010–2013, 41 (42.7%) Infection studies demonstrated that...
Although pseudorabies virus can affect a wide range of mammalian and avian hosts, swine are the only natural hosts virus. The US commercial industry obtained pseudorabies-free status in 2004, which was important because economic value domestic production; however, feral remain competent represent constant threat for reintroducing into industry. To better assess infection status, we collected 8,498 serum samples from across United States between 1 October 2009 30 September 2012. Of these, 18%...
We report whole-genome sequencing of influenza A virus (IAV) with 100% diagnostic sensitivity and results available in <24–48 h using amplicon-based nanopore technology (MinION) on clinical material from wild waterfowl ( n = 19), commercial poultry 4), swine 3). All 8 gene segments IAV including those 14 the 18 recognized hemagglutinin subtypes 9 11 neuraminidase were amplified their entirety at >500× coverage each 16 reference isolates evaluated. Subgenomic viral sequences obtained 3...
To determine whether, and to what extent, influenza A subtype H3 viruses were present in feral swine the United States, we conducted serologic virologic surveillance during October 2011-September 2012. These animals periodically exposed infected with A(H3N2) viruses, suggesting they may threaten human animal health.
ABSTRACT Influenza A viruses (IAVs) in swine can cause sporadic infections and pandemic outbreaks among humans, but how avian IAV emerges is still unclear. Unlike domestic swine, feral are free ranging have many opportunities for exposure through contacts with various habitats animals, including migratory waterfowl, a natural reservoir IAVs. During the period from 2010 to 2013, 8,239 serum samples were collected across 35 U.S. states tested against 45 contemporary antigenic variants of...
From 2011 to 2017, 4,534 serum samples from 13 wildlife species collected across the US and in one territory (US Virgin Islands) were tested for exposure Leptospira serovars Bratislava, Canicola, Grippotyphosa, Hardjo, Icterohaemorrhagiae, Pomona. Of 1,759 canids, 1,043 cervids, 23 small Indian mongooses ( Herpestes auropunctatus), 1,704 raccoons Procyon lotor), five striped skunks Mephitis mephitis), 27.0, 44.4, 30.4, 40.8, 60%, respectively, antibody positive any of six serovars. The most...
Abstract Subtype H7 avian–origin influenza A viruses (AIVs) have caused at least 500 confirmed human infections since 2003 and culling of >75 million birds in recent years. Here we antigenically genetically characterized 93 AIV isolates from North America (85 migratory waterfowl [1976–2010], 7 domestic poultry [1971–2012], 1 a seal [1980]). The hemagglutinin gene these are separated those Eurasia. Gradual accumulation nucleotide amino acid substitutions was observed the AIVs poultry....
Genetic reassortment between influenza A viruses (IAVs) facilitate emergence of pandemic strains, and swine are proposed as a "mixing vessel" for generating reassortants avian mammalian IAVs that could be risk to mammals, including humans. However, how transmissible reassortant emerges in not well understood. Genomic analyses 571 isolates recovered from nasal wash samples respiratory tract tissues group co-housed pigs (influenza-seronegative, H1N1 IAV–infected, H3N2 IAV–infected pigs)...
Avian bornaviruses, recently described members of the family Bornaviridae, have been isolated from captive parrots and passerines as well wild waterfowl in which they may cause lethal neurologic disease. We report detection avian bornavirus RNA brains apparently healthy gulls. tested 439 gull brain samples 18 states, primarily northeastern US, using a reverse-transcriptase PCR assay with primers designed to detect conserved region M gene. Nine birds yielded product appropriate size....
Given their free-ranging habits, feral swine could serve as reservoirs or spatially dynamic 'mixing vessels' for influenza A virus (IAV). To better understand shedding patterns and antibody response dynamics in the context of IAV surveillance amongst swine, we used origin to perform infection experiments. The was highly infectious transmissible were similar those domestic swine. In virus-inoculated sentinel groups, lasted ≤ 6 9 days, respectively. Antibody titres inoculated peaked at 1 : 840...
In Denmark and Greenland, extensive surveillance of avian influenza (AI) viruses in wild bird populations has been conducted from 2007 through 2010. Denmark, the consisted passive birds found dead or sick across active apparently healthy live waterfowl reservoirs along migratory flyways, living proximity to domestic poultry, hunted game birds. Dead were sampled by oropharyngeal swabbing. Healthy captured with nets, traps, hand swabbing cloacal tracts, swabs collected fresh fecal droppings....
Besides humans, H3 subtypes of influenza A viruses (IAVs) can infect various animal hosts, including avian, swine, equine, canine, and sea mammal species. These are both antigenically genetically diverse. Here, we characterized the antigenic diversity contemporary avian IAVs recovered from migratory birds in North America. Hemagglutination inhibition (HI) assays were performed on 37 isolates 2007 to 2011 using generated reference chicken sera. samples taken Atlantic, Mississippi, Central,...
A recent survey among wild birds demonstrated the presence of a unique genotype avian bornavirus (ABV) in geese and swans North America. Here, we report first complete genome sequence an goose genotype.
