Which does not refer to the shape of a virus?
A bacillus does not refer to the shape of a virus. The capsid of a virus is what determines the shape of a virus.
Is virus a verb?
No. Virus is a noun.
What is the scientific word for virus?
"virus"
Is smallpox virus or bacteria?
Smallpox was a virus.
An rna virus that makes copies of itself by using the path of host cells dna?
Rotavirus, Colorado tick fever virus, Rhinovirus, poliovirus, hepetatitis A virus, SARS, Yellow fever virus, West Nile virus, hepatitis C virus, Rubella virus just to mention a few.
What are the meanings of H - 5 - N - 1 in the H5N1 flu name?
It basically means "type 5 hemagglutinin, type 1 neuraminidase". These are proteins expressed by the virus. There are currently 17 known types of hemagglutinin and 9 known types of neuraminidase.
What do influenza viruses look like?
Unlike most viruses, the shape of influenza viruses is highly variable; however, their surface is consistently covered with protein spikes .There are eight RNA segments which encode 10 proteins. Two of the proteins, heamagglutinin and neuraminidase, make up the surface spikes. These proteins are antigenic, and antibody to them is what protects humans from influenza. Haemagglutinin (H) is the protein by which the virus attaches to its host cell. At present, there are 15 immunologically and genetically distinct haemagglutinin subtypes. Neuraminidase (N) is an enzyme that plays a role in releasing virions from their host cell, promoting the spread of infection. Nine neuraminidase subtypes have been identified. Only three haemagglutinin and two neuraminidase subtypes are commonly associated with human infections.
What is in the h1 n1 vaccene?
Neuraminidase inhibitors such as oseltamivir and zanamivir are found in the vaccine, and are used to block the neuraminidase protein in the viruses from working and prevent it from reproducing.
Do all flu viruses have H N?
All Type A influenza viruses have H and N (these are two proteins that are on the outer shell of the virus particle--Hemagglutinin and Neuraminidase). The other influenza virus types B and C each only have one serotype and they do not include the H and N.
What does the acronym AH1N1 stand for?
Influenza A Hemagglutinin 1 Neuraminidase 1
What would H1N1 be called if it came back even more advanced?
The influenza viruses are identified by and given names that correspond with the proteins on the capsid of the virus (outside coating of the virus). For example, the two proteins on the H1N1/09 virus are Hemagglutinin and Neuraminidase, therefore the virus is called H1N1.The name of any mutations of the H1N1/09 influenza virus, would follow this same naming convention and it would be called by the name that is descriptive of the particular proteins it has on the capsid after the mutation.See the related question below for more information on the naming of influenza viruses.
What does the medical abbreviation HN mean?
HN stands for hemagglutinin neuraminidase, a protein found in some viruses.
What are the meanings of A - H - N - 1 - 09 in the A H1N1 09 flu name?
Background information about names of flu virus strains:For background, H1N1 is the name used to identify several subtypes of flu viruses. A few of the influenza viruses that are in the group of Type A Influenza viruses are labeled that way or in similar ways.These influenza A virus strains are categorized according to two proteins found on the surface of the virus: hemagglutinin (H) and neuraminidase (N). All influenza A viruses contain hemagglutinin and neuraminidase, but the structure of these proteins differ from strain to strain due to rapid genetic mutation in the viral genome.Influenza A virus strains are assigned an H number and an N number based on which forms of these two proteins the strain contains. There are 16 H and 9 N subtypes known in birds, but only H 1, 2 and 3, and N 1 and 2 are commonly found in humans. There are also Influenza type B viruses.Example Swine Flu:An example is the new "Swine Flu" virus circulating in 2009, the "Influenza A, Novel H1N1/09" Virus. It evolved from a virus that started as a flu that only pigs could get, which is called H1N1, too. But that mutated to a strain that could also infrequently infect humans who were in very close contact with pigs, such as farmers who raised them. The new "Novel H1N1" virus was a further mutation that combined human, bird, and swine flu genes.The Centers for Disease Control and Prevention and World Health Organization call the pandemic 2009 "Swine Flu": Influenza A, Novel H1N1 Virus. You may also see it written as the "Novel H1N1 Influenza virus", or "Novel Influenza A, H1N1 virus", or "H1N1, formerly Swine Flu".It has different names in other countries as well, for example: it is called Schweinegrippe in Germany, la Grippe A in France, Mexican Flu in the Netherlands, SOIV (Swine Origin Influenza Virus) in Canada, and la epidemia in Mexico.The reason they call it "Novel" is that it is new. It is a strain not seen before. There are other strains of H1N1 influenza, but this one has different and new genetic material than the previously seen strains of Type A flu.What A-H1N1 means:"A" stands for the influenza sub-type or strain.These Type A viruses have a protein coating that surrounds them, called a capsid. The surface proteins making up the capsid in these virus strains are Hemagglutinin and Neuraminidase. These surface proteins are the parts of a virus that can be changed when viruses mutate into new forms. This is how they change to be able to attack the cells of new hosts or in new ways in the same hosts. They are no longer recognized as viruses that the immunological system of the host has fought before, and that allows them to mutate to forms that can evade the body's defenses again at first.In the naming convention of viruses, the protein classifications become part of the name as in H1N1; H for the Hemagglutininand N for the Neuraminidase. Hemagglutinin binds the virus to the cell it is infecting. Neuraminidase is an enzyme that lets the virus be released from the host carrier cell.There are different subtypes of viruses using the H and N nomenclature, for example the H5N1 subtype is the Avian (Bird) Flu.
How are viruses indentified?
The viruses are identified by a series of letters and numbers that refer to two proteins, hemagglutinin (HA) and neuraminidase (NA).
What do the 'H' and 'N' stand for in influenza viruses?
hemaglutinin and neuraminidase, two surface glycoproteins of influenza that contribute the the virulence of the disease...
What is flu notation?
Flu notation, or flue notation, is a system used in sheet music to indicate which holes need to be covered or uncovered to produce specific notes on a flute or similar wind instrument. It consists of symbols such as dots, lines, or numbers placed above or below the staff to instruct the player on finger placements for producing the desired pitch.
What is hemagglutinin inhibitor titer?
Haemagglutination inhibition test Influenza virus has two important surface glycoproteins-the haemagglutinin (HA) and the neuraminidase (NA). Antigenic classification and subtyping of influenza viruses is based on these two glycoproteins. HA plays a key role in virus cell entry by binding to cell surface receptors, which are found also on red blood cells of certain species. Binding to red cells results in haemagglutination, which can be observed as a carpet of agglutinated red cells at the bottom of a tube or microtitre well. In the haemagglutination inhibition test (HIT), antibody directed against the viral haemagglutinins block the virus from binding to the blood cells and thus inhibits the haemagglutination reaction
