Widespread human SARS-CoV-2 infections combined with human-wildlife interactions create the potential for reverse zoonosis from humans to wildlife. We targeted white-tailed deer (Odocoileus virginianus) serosurveillance based on evidence these have angiotensin-converting enzyme 2 receptors high affinity SARS-CoV-2, are permissive infection, exhibit sustained viral shedding, can transmit conspecifics, social behavior, and be abundant near urban centers. evaluated 624 prepandemic postpandemic...
We detected Eurasian-origin highly pathogenic avian influenza A(H5N1) virus belonging to the Gs/GD lineage, clade 2.3.4.4b, in wild waterfowl 2 Atlantic coastal states United States. Bird banding data showed widespread movement of within Flyway and between neighboring flyways northern breeding grounds.
Abstract Broad-scale data show SARS-CoV-2 occurrence in white-tailed deer throughout much of their range the conterminous United States and reinforce findings considerable infection exposure. Results shed light on both current infections prior exposure, with prevalence decreasing over time seroprevalence increasing. One-Sentence Summary White-tailed are infected with, have been exposed to, US.
Abstract Widespread human SARS-CoV-2 infections combined with human-wildlife interactions create the potential for reverse zoonosis from humans to wildlife. We targeted white-tailed deer ( Odocoileus virginianus ) serosurveillance based on evidence these have ACE2 receptors high affinity SARS-CoV-2, are permissive infection, exhibit sustained viral shedding, can transmit conspecifics, and be abundant near urban centers. evaluated 624 pre- post-pandemic serum samples wild four U.S. states...
Background Avian influenza viruses are known to productively infect a number of mammal species, several which commonly found on or near poultry and gamebird farms. While control rodent species is often used limit avian virus transmission within among outbreak sites, few studies have investigated the potential role these in dynamics. Methodology/Principal Findings We trapped sampled synanthropic mammals farm Idaho, USA that had recently experienced low pathogenic outbreak. Six six house mice...
Abstract The potential role of wild mammals in avian influenza A virus (IAV) transmission cycles has received some attention recent years and cases where birds have transmitted IAV to been documented. However, the contrasting cycle, wherein a mammal could transmit an birds, largely overlooked. We experimentally tested abilities two mammalian species mallards ( Anas platyrhynchos ) simulated natural environments. Results suggested that striped skunks Mephitis mephitis can successfully through...
ABSTRACT Influenza A viruses present a major challenge for animal and human health. They circulate widely in wild waterfowl frequently spillover into poultry, emphasizing the need risk-based surveillance birds an understanding of relative importance different transmission mechanisms. We addressed this objective with replicated ( N = 6) experimental infection study which we serially exposed eight cohorts four naïve contact mallards to experimentally infected mallard shared water pool. Viral...
Low-pathogenicity avian influenza virus (LPAIV) can lead to epizootics that cause economic losses in poultry or the emergence of human-infectious strains. LPAIVs experience a complex immunity landscape as they are endemic numerous host species, and many antigenically distinct strains co-circulate. Prevention control detrimental requires an understanding infection/transmission characteristics various subtypes different hosts, including interactions between subtypes. In order develop...
Background Striped skunks (Mephitis mephitis) are susceptible to infection with some influenza A viruses. However, the viral shedding capability of this peri-domestic mammal and its potential role in virus ecology largely undetermined. Methodology/Principal Findings were experimentally infected a low pathogenic (LP) H4N6 avian (AIV) monitored for 20 days post (DPI). All exposed AIV shed large quantities RNA, as detected by real-time RT-PCR confirmed live isolation, from nasal washes oral...
Avian influenza A viruses (IAVs) pose risks to public, agricultural, and wildlife health. Bridge hosts are spillover that share habitat with both maintenance (e.g., mallards) target poultry). We conducted a comprehensive assessment of European starlings ( Sturnus vulgaris ), common visitor urban agricultural environments, assess whether this species might act as potential or bridge host for IAVs. First, we experimentally inoculated wild bird IAV investigate susceptibility replication...
Migratory waterfowl are often viewed as vehicles for the global spread of influenza A viruses (IAVs), with mallards (Anas platyrhynchos) implicated particularly important reservoir hosts. The physical demands and energetic costs migration have been shown to influence birds' body condition; poorer condition may suppress immune function affect course IAV infection. Our study evaluated impact on viral shedding dynamics in naturally exposed an H9 IAV, then secondarily H4N6 IAV. Mallards were...
European starlings (Sturnus vulgaris) are a known risk factor for the occurrence of microorganisms that pathogenic to cattle and humans in concentrated animal feeding operations (CAFOs). Starling use CAFOs is vary response weather; starling control on often timed coincide with favorable environmental conditions maximize take. The totality this information suggests disease risks associated may be infl uenced by factors, such as temperature. In study, we assessed Salmonella enterica...
The effects of flock size European starlings (Sturnus vulgaris) was experimentally manipulated to assess the potential influenza A virus (IAV; H4N6) transmission from a flocking passerine bobwhite quail (Colinus virginianus) through shared food and water resources mimic starling intrusions into free-range backyard poultry operations. Of three sizes tested (n = 30, n 20 10), all successfully transmitted or most in each animal room (6/6, 6/6 5/6) by end experimental period, as determined...
Using data on waterfowl band recoveries, we identified spatially explicit hotspots of concentrated movement to predict occurrence and spatial spread a novel influenza A virus (clade 2.3.4.4) introduced from Asia by an initial outbreak in North America November 2014. In response the outbreak, were used help guide sampling for clade 2.3.4.4 viruses as early warning US poultry industry during . After surveillance waterfowl, tested whether there was greater detection inside hotspots. We found...

Abstract Several investigations have recently assessed the ability of some aquatic invertebrates to act as tools for avian influenza A virus (IAV) surveillance well their potential role(s) in IAV ecology. Because this, high seroprevalence rates noted select mesocarnivores that commonly inhabit and semi‐aquatic habitats, we evaluated effects freshwater crayfish on water at three dose levels monitored presence tissues (gill green gland) haemolymph multiple time points. At relatively high,...
