What does serrotype mean?
A serotype is a classification within a species based on the variation of surface antigens, like proteins or sugars, on the bacterial or viral cell. Serotyping helps identify and differentiate strains of pathogens, such as bacteria or viruses, for research, treatments, and outbreak investigations.
What is the use of the tail of a virus?
The tail of a virus, particularly in bacteriophages (viruses that infect bacteria), plays a crucial role in the infection process. It functions as a mechanism for attachment to the host cell, allowing the virus to inject its genetic material into the bacterial cell. The tail can also aid in the recognition of specific receptors on the bacterial surface, ensuring that the virus targets the appropriate host. Overall, the tail is essential for the successful entry of the virus into its host.
What are the kingdoms of corona viruses and rhino viruses?
Coronaviruses and rhinoviruses belong to different families within the realm of viruses. Coronaviruses are classified under the family Coronaviridae and are known for their crown-like appearance due to spike proteins on their surface. Rhinoviruses, on the other hand, belong to the family Picornaviridae and are primarily responsible for the common cold. Both types of viruses are RNA viruses, but they differ significantly in their structure, transmission, and the diseases they cause.
Viruses need water to survive?
they move from person to person and regenerate... some feed on your red blood cells, while others infuse themselves into your dna so white blood cells cant fight them. they then replicate themselves. the only way to kill a virus is to isolate all who have it, which is impossible in the case of certain ones... like the flu. everyone has it at sometime
Cultivation of viruses in embryonated egg culture?
In clinical virology the use of embryonated eggs are frequently used because viruses need something living for the viruses characteristics to come out. It is frowned upon to use monkey and rats for this during school so embryonated eggs are the next best things.
What is the geometric shape does a virous prefer?
Viruses have different geometrical shapes, such as helical and polyhedral shapes. A particular polyhedral shape common to many viruses is a dodecahedron shape. This is a geometric shape that has 12 sides.
Do Compare and contrast helical and icosahedral viral shapes and diseases?
Helical viruses have a rod-like shape with a helical symmetry, such as the tobacco mosaic virus, while icosahedral viruses have a polyhedral shape made up of 20 equilateral triangular faces, like adenoviruses. Diseases caused by helical viruses include Ebola and influenza, while diseases caused by icosahedral viruses include the common cold and polio.
What is structure viruses?
A virus has a protein coat called a capsid with either DNA or RNA inside. A virus can have one of three structures. These are: 1. Helical virus. A helical virus is rod- or thread-shaped. The virus that causes rabies is a helical virus. 2. Icosahedral virus. An icosahedral virus is spherically shaped. Viruses that cause poliomyelitis and herpes simplex are icosahedral viruses. 3. Polyhedral Cylindrical shapes: Tobacco mosaic virus Wheat streak virus Hepatitis C
Are helical viruses rod shaped?
Yes, helical viruses have a rod-shaped structure. These viruses consist of a cylindrical or helical capsid that encloses the viral genetic material, which can be DNA or RNA. The helical capsid gives these viruses their rod-shaped appearance.
What is viruses made of?
The most basic viruses are composed of either RNA or DNA and are surrounded by a layer of protein subunits. Some viruses have a viral envelope that serves to protect the virus from the immune system and helps with adhesion of a virus to other things. The complex viruses consist of an icosahedral head attached to a helical tail often attached to protein fibers that can look like 'legs'.
What is the general shape of viruses?
A virus can have one of two structures. These are: •Helical virus. A helical virus is rod- or thread-shaped. The virus that causes rabies is a helical virus. •Icosahedral virus. An icosahedral virus is spherically shaped. Viruses that cause poliomyelitis and herpes simplex are icosahedral viruses.
How do animal viruses differ from bacterial viruses?
retro virus = any of a family of single-stranded RNA viruses having a helical envelope and containing an enzyme that allows for a reversal of genetic transcription, from RNA to DNA rather than the usual DNA to RNA, the newly transcribed viral DNA being incorporated into the host cell's DNA strand for the production of new RNA retroviruses: the family includes the AIDS virus and certain oncogene-carrying viruses implicated in various cancers.
Are viruses classified by their shape?
A virus can have one of two structures. These are: •Helical virus. A helical virus is rod- or thread-shaped. The virus that causes rabies is a helical virus. •Icosahedral virus. An icosahedral virus is spherically shaped. Viruses that cause poliomyelitis and herpes simplex are icosahedral viruses.
How do viruses get into bacterial cell?
A virus has proteins on its capsid that bind to living host cell. Once the virus has attached it enters the cell or inserts DNA/RNA into the cell.
What is a nuclear polyhedral virus?
This virus' image, using an electron microscope, shows an inclusion which appears to be similar to a nucleus. (Viruses have strands of RNA or DNA but no nucleus.) That is where the "nuclear" originates from. Polyhedral means that the virus has many sides. This is one of three shapes that viruses show. It affects the Wattle Bag Worm, the Korean Gypsy Moth, and cabbage leaves.
What is the helical virus?
The helical virus is a type of virus that has a capsid structure in the shape of a helix. This helical structure is formed by protein subunits arranged in a spiral around the viral genetic material. Examples of helical viruses include tobacco mosaic virus and influenza virus.
What are viruses that prevent bacteria?
Viruses that prevent bacterial infections are called as "bacteriophages".
