give the detail about type of bacteria and give short answer about virus, fungus,and it medcine
Answers
Answer:
Bacteria (bak-TEER-ee-uh) are tiny, single-celled organisms that get nutrients from their environments. In some cases, that environment is your child or some other living being.
Some bacteria are good for our bodies — they help keep the digestive system in working order and keep harmful bacteria from moving in. Some bacteria are used to make medicines and vaccines.
But bacteria can cause trouble too, as with cavities, urinary tract infections, ear infections, or strep throat. Antibiotics are used to treat bacterial infections.
Viruses
Viruses are even smaller than bacteria. They aren't even a full cell. They are simply genetic material (DNA or RNA) packaged inside of a protein coating. They need to use another cell's structures to reproduce. This means they can't survive unless they're living inside something else (such as a person, animal, or plant).
Viruses can only live for a very short time outside other living cells. For example, viruses in infected body fluids left on surfaces like a doorknob or toilet seat can live there for a short time. They'll die quickly unless a live host comes along.
When they've moved into someone's body, though, viruses spread easily and can make a person sick. Viruses cause minor sicknesses like colds, common illnesses like the flu, and very serious diseases like smallpox or HIV/AIDS.
Antibiotics are not effective against viruses. Antiviral medicines have been developed against a small, select group of viruses.
Fungi
Fungi (FUN-guy) are multicelled, plant-like organisms. A fungus gets nutrition from plants, food, and animals in damp, warm environments.
Many fungal infections, such as athlete's foot and yeast infections, are not dangerous in a healthy person. People with weak immune systems (from diseases like HIV or cancer), though, may get more serious fungal infections.
