The genetics of virus particle shape in equine influenza A virus [PDF]

Influenza and Other Respiratory Viruses, 2013
BackgroundMany human strains of influenza A virus produce highly pleomorphic virus particles that at the extremes can be approximated as either spheres of around 100 nm diameter or filaments of similar cross‐section but elongated to lengths of many microns.

Evolution of equine influenza virus in vaccinated horses. [PDF]

J Virol, 2013
ABSTRACT Influenza A viruses are characterized by their ability to evade host immunity, even in vaccinated individuals. To determine how prior immunity shapes viral diversity in vivo , we studied the intra- and interhost evolution of equine influenza virus in vaccinated horses.

TRIALS FOR PREPARATION AND EVALUATION OF PEROXIDASE AND FLUORESCENT ISOTHIOCYANATE CONJUGATED ANTISERA AGAINST EQUINE INFLUENZA VIRUS [PDF]

Veterinary Medical Journal - Giza, 2004
The present study was designed to produce antiinfluenza antibodies conjugated by peroxidase and fluorescein isothiocyanate separately for rapid detection of equine influenza (El) virus. Five rabbits were immunized with equine influenza (El) virus (A/equi/

Full-Length Genome of the Equine Influenza A Virus Subtype H3N8 from 2019 Outbreak in Saudi Arabia

Animals, 2022
Equine influenza is a major cause of respiratory infections in horses and can spread rapidly despite the availability of commercial vaccines. This study aimed to screen the incidence of equine influenza virus (EIV) and molecularly characterize the ...

Cloning the Horse RNA Polymerase I Promoter and Its Application to Studying Influenza Virus Polymerase Activity

Viruses, 2016
An influenza virus polymerase reconstitution assay based on the human, dog, or chicken RNA polymerase I (PolI) promoter has been developed and widely used to study the polymerase activity of the influenza virus in corresponding cell types. Although it is

Long-term adaptation following influenza A virus host shifts results in increased within-host viral fitness due to higher replication rates, broader dissemination within the respiratory epithelium and reduced tissue damage.

PLoS Pathogens, 2021
The mechanisms and consequences of genome evolution on viral fitness following host shifts are poorly understood. In addition, viral fitness -the ability of an organism to reproduce and survive- is multifactorial and thus difficult to quantify. Influenza

Intra- and Interhost Evolutionary Dynamics of Equine Influenza Virus [PDF]

Journal of Virology, 2010
ABSTRACT Determining the evolutionary basis of cross-species transmission and immune evasion is key to understanding the mechanisms that control the emergence of either new viruses or novel antigenic variants with pandemic potential. The hemagglutinin glycoprotein of influenza A viruses is a critical host range determinant and a major target ...
