Some viruses attack and destroy fungi and bacteria that is toxic to humans. The name of this helpful virus is bacteriophage (sometimes called phage).
Genetically engineered viruses are the common types of viruses that are helpful to humans. However, biological viruses are the viruses that typically cause harm to humans.
for me i think some viruses are also useful to man like tobacco mosaic virus
I believe there aren't any helpful viruses.
BUT......
Some viruses target harmful organisms
They absorb fats from the body which help people lose weight.
yes very useful.
Inert virii can be used to insert genetic material into cells so yes they are useful to a microbiologist.
both
They can kill you.
Yes.Fungi is useful to us.They are used to make medicines.
Emerging viruses
Viruses that are harmless to humans can be used to infect bacteria or other pests eg rabbits
Because bacteria have only DNA as genetic material but viruses have RNA or DNA as genetic material. viruses are harmful but most of the bacteria are useful.
No. Any and all viruses are parasitic. There may not be any helpful viruses, but there are certainly a large quantity of harmless viruses, which doesn't infect humans, but rather specific animals or plants.
useful effect viruses
Regardless of the pathogenicity of certain viruses, benign viruses CAN be used to carry vaccines into the blood stream and cells, thereby being useful. Other viruses, such as those which live in (or off of) certain plants cause that plant to produce certain useful (at least to humans) chemicals such as anti-bacterial compounds. Viruses will also most likely be the first carrier vector of DNA therapy for a variety of human and animal illnesses, since they easily enter cell membranes and can insert their DNA or RNA into the host cell's own genetic material
Viruses and some bacteria aren't useful.
They can kill you.
Its useful to see very small microorganisms & useful to study about small viruses etc.
the viruses help the immune system adapt and get stronger
the flu...
Snakes don't help humans..but they are useful for entertainment..but are dangerous.
Yes.Fungi is useful to us.They are used to make medicines.
Emerging viruses
its not useful for the refrigerator its useful for humans only....
