Human adaptation of avian influenza viruses
Human adaptation of avian influenza viruses pose an enormous public health challenge as the human population is predominantly naive to avian influenza antigens. As such, constant surveillance is needed to monitor the circulating avian strains. Of particular importance are strains belonging to H5N1, …

Prevelance of Avian Influenza Viruses in Northern Zambia
This study described the prevalence of avian influenza viruses in wild waterfowl and domestic birds on the wetlands of Northern Zambia (Luapula and Northern Provinces). The purpose of the research was to establish if there are any influenza viruses circulating in this region in order to determine …

Phylogenetic approaches for quantifying the genotypic diversity of influenza viruses
… birds are thought to be the main reservoir for Influenza A viruses, hosting the largest burden of influenza diversity generated by high frequencies of co-infection and segment reassortment. The recently emerged avian influenza viruses that spilled-over into the human population were all produced …

Identification of reassortant influenza viruses at scale : algorithm and applications
… most prominent virus known to reassort is the influenza A virus. Methods to identify reassortant influenza viruses do not scale well beyond hundreds of isolates at a time, because they rely on phylogenetic reconstruction, a computationally expensive method. This thus hampers our ability to test …

Vertical Concentration Gradient of Influenza Viruses Resuspended from Floor Dust
… focuses on predicting the concentration of influenza A viruses in resuspended dust, generated by people walking in a room, at various heights above the floor. Using a sonic anemometer, we measured the velocity field from floor to ceiling at 10-cm intervals to estimate the magnitude of …

Modelling the Epidemiological Dynamics of Seasonal Influenza Viruses at Local Scales
Seasonal influenza viruses are a substantial source of disease burden globally, causing epidemics across all climatic regions. Through error-prone RNA replication, influenza viruses can escape pre-existing humoral immunity and reinfect humans, resulting in recurrent epidemics within populations. …

Predicting the Antigenic Evolution of Influenza Viruses with Application to Vaccination Strategy
Seasonal influenza viruses cause substantial worldwide mortality and morbidity every year. The evolution of these viruses comprise unique systems for studying natural evolutionary processes in real-time. Host immune systems recognise pathogens based on binding affinities between host antibodies and …

Investigating the spread of emerging Avian Influenza viruses using cross-disciplinary and computational approaches
Avian Influenza (AI) is a viral disease that affects birds and humans. Several AI lineages infect humans and there is potential for lineages to cause human pandemics. New developments in AI have occurred in recent years: several novel zoonotic strains (e.g. H7N9, H5N6, H10N8) emerged in China, and …

Seasonal Dynamics of Avian Influenza Viruses in Ring-billed Gulls (Larus delawarensis) in Minnesota
… are reservoir hosts for low pathogenicity avian influenza viruses (LPAIVs), but their role in the transmission dynamics of highly pathogenic avian influenza viruses (HPAIVs) is unclear. The novel reassortant HPAIV H5N2 that emerged in Minnesota in 2015 was devastating to the poultry industry, …

Reverse Zoonosis of Pandemic A(H1N1)pdm09 Influenza Viruses at the Swine/Human Interface
<p>The 2009 pandemic influenza A(H1N1)pdm09 virus emerged from the swine population. Despite frequent zoonotic events, swine influenza viruses had not become established in humans previously and little is known about host-barriers which prevent swine influenza viruses from efficiently infecting …

Virologic Factors Contributing to the Genetic Diversification of Influenza Viruses Circulating in North American Swine
… to determine mechanisms of reassortment of swine influenza viruses and determine if certain reassortant gene combinations can drive evolution and host adaptation in the context of the triple reassortant internal gene (TRIG) cassette. The TRIG contains a unique combination of a human polymerase …

The role of domestic ducks in the maintenance and spread of avian influenza viruses in Indonesia
… birds serve as the natural reservoir host for influenza A viruses. As the reservoir, wild waterfowl play an important role in the persistence and transmission of influenza viruses among bird populations and to other mammalian species. In many Asian countries, domestic ducks are raised for meat …

Strategy for speedy field diagnosis and control of avian influenza viruses (AIV) outbreak at the point of contact/care (POC)
Avian influenza (AI) is an infectious viral disease in birds caused by a type A influenza virus of the family Orthomyxoviridae. These viral outbreaks usually cause significant economic losses to the poultry industry. Conventional strategies for AI detection and control using vaccination both start …

INTERSPECIES TRANSMISSION AND HOST RESTRICTION OF INFLUENZA A VIRUSES
Type A influenza viruses can infect both mammals including humans, pigs, horses, cats, dogs, ferrets, and sea mammals as well as domestic and wild birds. Although influenza A viruses shows host range restrictions, interspecies transmission have been documented at many occasions. Swine have been …

Dissecting Human Antibody Responses Against Influenza A Viruses And Antigenic Changes That Facilitate Immune Escape
Influenza A viruses pose a serious threat to public health, and seasonal circulation of influenza viruses causes substantial morbidity and mortality. Influenza viruses continuously acquire substitutions in the surface glycoproteins hemagglutinin (HA) and neuraminidase (NA). These substitutions …

Epidemiology of Swine Influenza Virus in Cattle (Respiratory Diseases)
Various strains of influenza viruses have been isolated from ruminants and antibody responses detected by serological tests. The widespread occurrence of swine influenza virus (SIV) justifies studies to assess the importance of other animals that cohabitate with swine as potential reservoirs.
