Moreover, outbreaks of IDV in swine and bovine are increasing, and more genetic and serological evidences show that IDV has a potential to adapt to humans.IDV is unique among four types of influenza viruses. The thermal and acid stability of IDV were examined and directly compared with those ...
The influenza viruses are characterized by segmented, negative-strand RNA genomes requiring an RNA-dependent RNA polymerase of viral origin for replication. The particular structure of the influenza virus genome and function of its viral proteins enable antigenic drift and antigenic shift. These processes...
Influenza Virus: The Biology of a Changing Virus Samira Mubareka and Peter Palese Abstract Influenza viruses are members of the family Orthomyxoviridae and include influenza virus types A, B, and C. This introduction provides an overview of influenza virus classification, structure, and life cycle....
B, and C. This introduction provides an overview of influenza virus classification, structure, and life cycle. We also include a brief review of the clinical manifestations of influenza and the molecular determinants for virulence. The genetic diversity of influenza A viruses and their capability...
Free Essay: Influenza also known as the flu will be the next virus of discussion. Like Ebola and HIV; Influenza is characterized as an enveloped virus but...
The Influenza Virus and Its Genome The name "influenza" is derived from the Latin word for "influence," and thethat cause this disease areRNAviruses from the family Orthomyxoviridae. The genomes of all influenza viruses are composed of eight single-stranded RNA segments (Figure 1). These RNAs...
Influenza A viruses (IAVs) constitute a major threat to human health. The IAV genome consists of eight single-stranded viral RNA segments contained in separate viral ribonucleoprotein (vRNP) complexes that are packaged together into a single virus particle. The structure of viral RNA is believed ...
We argue that it is premature to become complacent, and we identify research directions in influenza virus ecology and the molecular biology of pathogenesis and transmission that should enable the development of better predictors of seasonal and pandemic influenza and increased preparedness (Figure 1)....

1.Any of a large group of disease-causing agents consisting of a segment of RNA or DNA within a protein shell. All viruses are parasites because they can reproduce only inside the cells of plants, animals, and bacteria. Viruses are usually not considered living organisms. ...
