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.


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 an antiphage?

Antiphage is a substance that includes live cultures which can be used to assist with the development of serums which may assist human immune systems with fighting some diseases. Antigen-binders can be combined with synthetically created antibodies in the process of creating Antiphage serums.


Three functional roles of bacterial capsules?

The capsule allows bacteria to spread diseases easily by preventing phagocytosis. It also prevents the dessication. It prevents bacterial viruses to get in the cell and also prevents hydrophobic toxins from toxicating the cell.

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.


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 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.


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 are viruses that prevent bacteria?

Viruses that prevent bacterial infections are called as "bacteriophages".


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 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.
