Influenza B virus. Influenza B virus is the only species in the genus Betainfluenzavirus in the virus family Orthomyxoviridae . Influenza B virus is only known to infect certain mammal species, including humans, ferrets, pigs, and seals. [ 4][ 5] This limited host range is apparently responsible for the lack of influenza pandemics associated ...
Treatments for influenza include a range of medications and therapies that are used in response to disease influenza. Treatments may either directly target the influenza virus itself; or instead they may just offer relief to symptoms of the disease, while the body's own immune system works to recover from infection.
Influenza, commonly known as " the flu " or just " flu ", is an infectious disease caused by influenza viruses. Symptoms range from mild to severe and often include fever, runny nose, sore throat, muscle pain, headache, coughing, and fatigue. These symptoms begin one to four (typically two) days after exposure to the virus and last for about ...
The HI assay is generally performed by creating a dilution series of antiserum across the rows of a 96-well microtiter plate. Each row would usually be a different sample. A standardized amount of virus or bacteria is added to each well, and the mixture is allowed to incubate at room temperature for 30 minutes.
The Influenza Genome Sequencing Project ( IGSP ), initiated in early 2004, seeks to investigate influenza evolution by providing a public data set of complete influenza genome sequences from collections of isolates representing diverse species distributions. The project is funded by the National Institute of Allergy and Infectious Diseases ...
Polyvalent influenza vaccine. Polyvalent influenza vaccine is a type of influenza vaccine that provides immunity against more than one type of antigen. [1] In the second week after receiving the flu shot, the body's immune system is triggered by the antigens so the body starts producing antibodies. These antibodies help fight against influenza ...
Influenza (flu) Avian influenza, also known as avian flu or bird flu, is a disease caused by the influenza A virus, which primarily affects birds but can sometimes affect mammals including humans. [ 1] Wild aquatic birds are the primary host of the influenza A virus, which is enzootic (continually present) in many bird populations. [ 2][ 3 ...
Articulavirales. Family: Orthomyxoviridae. Genus: Alphainfluenzavirus. Species: Influenza A virus. Influenza A virus (IAV) is the only species of the genus Alphainfluenzavirus of the virus family Orthomyxoviridae. [ 1] It is a pathogen with strains that infect birds and some mammals, as well as causing seasonal flu in humans. [ 2]
