Avian Influenza

Avian influenza is a viral disease caused by various strains of avian influenza viruses that can be classified as low pathogenic avian influenza (LPAI) or highly pathogenic avian influenza (HPAI). It remains a global disease with potential high consequence with the potential to threaten wildlife, agriculture, and human health.

Little Brown Bats (Myotis lucifugus) weights and Ct values for SARS-CoV-2 Infection challenge Little Brown Bats (Myotis lucifugus) weights and Ct values for SARS-CoV-2 Infection challenge

Little brown bat (Myotis lucifugus) weights and SARS-CoV2 test results were collected as part of study to assess transmission potential of SARS-CoV2 in North American bat populations. It has been proposed that the SARS-CoV-2 virus originated in Asian bats and subsequently spread through human populations as a pandemic. There is concern that infected humans could transmit the virus to...

Dataset: Sero-surveillance for avian influenza exposure in wild birds in Iceland, 2012-2017 Dataset: Sero-surveillance for avian influenza exposure in wild birds in Iceland, 2012-2017

From 2010-2018 we investigated the occurrence of avian influenza antibody in wild birds in Iceland. A total of 2453 serum samples were collected from wild birds. We tested all samples by enzyme-linked immunosorbent assay (ELISA) for evidence of previous exposure to avian influenza virus with 1302 testing positive.

Experimental infection of Mexican free-tailed bats (Tadarida brasiliensis) with SARS-CoV-2 Experimental infection of Mexican free-tailed bats (Tadarida brasiliensis) with SARS-CoV-2

We experimentally challenged wild Mexican free-tailed bats (TABR) with SARS-CoV-2 to determine the susceptibility, reservoir potential, and population impacts of infection in this species. Of nine bats oronasally inoculated with SARS-CoV-2, five became infected and orally excreted moderate amounts of virus for up to 18 days post inoculation. These five subjects all seroconverted and...

A total of 6635 swabs samples were collected from wild birds or fecal material directly associated with wild birds. We screened all samples by a real time - polymerase chain reaction (RT-PCR) test with 381 testing positive. Further testing of all RT-PCR positive samples and all negative...

Little brown bats (Myotis lucifugus) are resistant to SARS-CoV-2 infection Little brown bats (Myotis lucifugus) are resistant to SARS-CoV-2 infection

It has been proposed that the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) virus that spread through human populations as a pandemic originated in Asian bats. There is concern that infected humans could transmit the virus to native North American bats; therefore, the susceptibility of several North American bat species to the pandemic virus has been experimentally...

Background: The geographic expansion and evolution of A/Goose/Guangdong/1/1996(H5N1) (Gs/GD) lineage H5Nx highly pathogenic avian influenza (HPAI) viruses since 1996 have raised awareness of enzootic circulation among migratory birds and the potential for intercontinental transport and spread.

The severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) virus is thought to have originated in wild bats from Asia, and as the resulting pandemic continues into its third year, concerns have been raised that the virus will expand its host range and infect North American wildlife species, including bats. Mexican free-tailed bats (Tadarida brasiliensis) live in large colonies in...

Global dissemination of Influenza A virus is driven by wild bird migration through arctic and subarctic zones Global dissemination of Influenza A virus is driven by wild bird migration through arctic and subarctic zones

Influenza A viruses (IAV) circulate endemically among many wild aquatic bird populations that seasonally migrate between wintering grounds in southern latitudes to breeding ranges along the perimeter of the circumpolar arctic. Arctic and subarctic zones are hypothesized to serve as ecologic drivers of the intercontinental movement and reassortment of IAVs due to high densities of...
