THE ANTIBODY RESPONSE TO SWINE INFLUENZA [PDF]

Journal of Experimental Medicine, 1939
Antibodies that neutralize swine influenza virus became detectible in the serum of swine on the 6th or 7th day after infection with swine influenza. Their appearance corresponded rather closely with clinical recovery. In swine with the milder filtrate disease, neutralizing antibodies did not appear until sometime between the 7th and 10th days.

Evidence of H10N8 influenza virus infection among swine in southern China and its infectivity and transmissibility in swine

Emerging Microbes and Infections, 2020
Infection with a novel H10N8 influenza virus in humans was first described in China in December 2013, which raised concerns related to public health. This novel virus was subsequently confirmed to have originated from a live poultry market.

Regional Transmission and Reassortment of 2.3.4.4b Highly Pathogenic Avian Influenza (HPAI) Viruses in Bulgarian Poultry 2017/18

Viruses, 2020
Between 2017 and 2018, several farms across Bulgaria reported outbreaks of H5 highly-pathogenic avian influenza (HPAI) viruses. In this study we used genomic and traditional epidemiological analyses to trace the origin and subsequent spread of these ...

Causal analysis of trade loss from pathogens: A global study of foot and mouth disease impacts on meat exports

American Journal of Agricultural Economics, EarlyView.
Abstract Our general interest is in global trade loss from livestock pathogens, specifically exports. We adopt a causal inference approach that considers animal disease outbreaks over time as non‐staggered binary treatments with the potential for switching in (infection) and out of treatment (recovery) within the sample period. The outcome evolution of

Genetic variations of nucleoprotein gene of influenza A viruses isolated from swine in Thailand

Virology Journal, 2010
Background Influenza A virus causes severe disease in both humans and animals and thus, has a considerably impact on economy and public health. In this study, the genetic variations of the nucleoprotein (NP) gene of influenza viruses recovered from swine

Risk management externalities in agrifood supply chains

American Journal of Agricultural Economics, EarlyView.
Abstract Firms may under‐ or over‐invest in risk management from the social planner's perspective, resulting in a negative externality on other economic agents in the supply chain. The externality of risk management is particularly relevant for agrifood supply chains, which frequently experience disruptions and play a primary role in preventing major ...

Ferritin as a Nanoparticle Scaffold for Plant‐Produced Next‐Generation Subunit Vaccines

Biotechnology and Bioengineering, EarlyView.
ABSTRACT Protein nanoparticles offer an innovative approach to next‐generation subunit vaccine development by displaying antigenic sequences on the nanoparticle surface. Compared to traditional subunit vaccines, protein nanoparticle vaccines often show improved interaction with the immune system due to their particulate size and repetitive epitope ...

Long-Term Epidemiology and Evolution of Swine Influenza Viruses, Vietnam

Emerging Infectious Diseases, 2023
Influenza A viruses are a One Health threat because they can spill over between host populations, including among humans, swine, and birds. Surveillance of swine influenza virus in Hanoi, Vietnam, during 2013–2019 revealed gene pool enrichment from ...

Low dose influenza virus challenge in the ferret leads to increased virus shedding and greater sensitivity to oseltamivir [PDF]

, 2014
Ferrets are widely used to study human influenza virus infection. Their airway physiology and cell receptor distribution makes them ideal for the analysis of pathogenesis and virus transmission, and for testing the efficacy of anti-influenza ...

Genetic diversity and circulation of influenza A viruses in Italian pig farms: insights from surveillance and vaccination

Porcine Health Management
Background The genetic diversity of influenza A viruses in swine (IAV-S) in Europe, including key subtypes such as H1N1, H3N2, H1N2, and H1N1pdm09 (which features H1 hemagglutinin genes from the H1A, H1B, and H1C genetic clades), presents challenges for ...
