Viruses (biological)

A vector is an organism, typically an insect or rodent, that can carry and transmit disease-causing agents such as viruses or bacteria into a host cell. Vectors play a crucial role in the transmission of diseases like malaria, dengue fever, and Lyme disease.

Viruses do not possess the necessary mechanisms to acquire nutrients, process them and use them for metabolism. Instead, they 'hijack' a host cell and use the mechanisms of the host cell to replicate itself.

One of the gud example is HIV virus because genetic material of the virus incorporated into the host genetic material and suppress the host metabolic activity it make strength resemble to host .if we can use drugs against virus it doesnt identify different btwn host and virus.so that drugs cause side effects in host .

IgG antibodies account for the bulk of circulating antibodies in the blood. They are the most abundant class of antibodies and play a crucial role in providing long-term immunity.

The virus takes over a cell's DNA and forces it, along with some of the viruses own DNA as a 'blueprint' to make more viruses.

The process is called vaccination. It involves injecting a person with a harmless form of a pathogen, such as a dead or weakened virus or bacteria, to stimulate the immune system to produce an immune response without causing the disease.

Both colds and flu are caused by viruses, with colds commonly caused by rhinoviruses and flu commonly caused by influenza viruses. Both types of viruses infect the respiratory system, leading to symptoms such as coughing, sneezing, and a runny nose.

"TNTC" in microbiology stands for "too numerous to count." It is used when a sample has a very high number of microorganisms or cells, making it impossible to accurately quantify them individually.

Viruses can remain dormant in a cell until conditions become favorable for replication. Factors such as a weakened immune system or stress can trigger the virus to become active again.

The mechanism for the release of an enveloped virus is called "budding". The virus picks up a part of the host's cell membrane to cover its' own protein coat. This happens when the host cell releases the viruses. The cell doesn't bust open with budding.

Viral infections can lead to cancer by integrating viral DNA into the host cell's genome, causing mutations that disrupt normal cell growth control mechanisms. Some viruses can also promote inflammation, which can create an environment conducive to cancer formation. Additionally, viral proteins may interfere with key cellular processes, leading to uncontrolled cell division and tumor formation.

virus is a disease which is caused by virus

It is called leukocyte extravasation - as in Leukocyte (white blood cell) extra- (outside) -vas- (vascular) -ation

Nutrient agar supports the growth of fewer organisms compared to a complex medium because it contains fewer nutrients. Complex media typically have a more diverse array of nutrients, allowing for the growth of a wider variety of organisms.

The complexity of a viruses it depend on their genome.Larger genome, more genes more complex structure.Their are some viruses that produce only three genes.Hepatitis D virus with 1700 nucleotides its knowed as the smallet virus that infect animals.It replicate only in presence of hepatitis B.It has an outer coat containing three HBV envelope proteins

Not at all, because Haemophilus influenzae (Hib) is the name of a type of bacteria and the flu is caused by viruses;they are entirely different infectious disease-causing organisms. Although the name includes "influenzae" it is not a "flu" virus. When this bacterium was first named in 1892, it was during an influenza pandemic at the time. It was thought then to be the cause of the influenza until 1933 when more was known about viruses and Hib was determined more conclusively to be bacterial and not viral. H. influenzae causes a wide range of different infectious disease processes but it does not cause the flu.

because bacteia that are present will contaminate the plates that will be used to isolate phages and will be imposible to detect the phages.Normally sewage are filter sterilized before isolation.

No, a black hole is not a virus. A black hole is a region in space where gravity is so strong that nothing, not even light, can escape from it. It is formed when a massive star collapses in on itself.

it is a virus which is also caused of measles

The virus head is responsible for protecting and encapsulating the genetic material of the virus, such as DNA or RNA. It helps the virus attach to host cells and inject its genetic material to initiate the infection process. The head also plays a role in facilitating the release of the genetic material into the host cell for replication.

it will cause a disease in the organism

A cold is a virus and you catch it from someone else or by touching something someone else has touched. This is why you should wash your hands a lot during cold season. You do not catch a cold from being cold.

The action carried out by a virus when it is activated is typically referred to as executing or running. This involves the virus code being triggered and performing its intended functions, which could include replicating itself, corrupting files, or stealing data.

pathogen/host

In general, treatment for influenza consists of medical support - IV fluids if the animal is dehydrated, antibiotics for any secondary bacterial infections, etc. There are no antivirals for animals, unlike for humans.
