There are literally thousands. Some help us digest our food. Some process our food so that it is not toxic for us to even eat. Some process our foods to increase / add flavor. Some process our wastes. Some are food sources for larger organisms... starting a food chain with us at the top. They become problems when they are concentrated too much, or are concentrated in the wrong places. In general, anaerobic bacteria are only good for processing wastes, and are otherwise very bad.
The normal flora, i.e. those bacteria that live on our skin and in our body cavities. They are normally not harmful to us and their presence makes it difficult if not impossible for other bacteria to survive on/in us. Some of the normal flora even "give something in return", e.g. E. coli in the gastrointestinal tract metabolize complex carbohydrates (polysaccharides) like cellulosa into smaller saccharides that we can absorb. Cellulosa is found for instance in salad.
Rhizobia bacteria convert nitrogen gas into other substances that help plants grow. This in the long run will allow more plants to give more oxygen for humans to breathe. E Coli also helps humans digest food as well as producing vitamins.
Bacteria need food, warmth, oxygen and moisture to survive.

The bacteria which help in humans is e-coli ,eschiricia -coli which is present in human intetine ,which help us in degistion of our food.
Yes they do. Bacteria is not always harmful. Some bacteria helps the body maintain homeostasis.
They need air, food and water to survive.

symbiontBacteria can form good and bad relationships with many other organism and humans. In plants and humans good bacteria creates enzymes which help digest food and get rid of waste. Bad bacteria can cause destruction of good cell which could cause infection.

No, because they are a type of bacteria. Even though bacteria can be bad there is also some good bacteria as well. We need the good bacteria for medicine like penicillin and other things
It has few or no side effects in humans. it kills different types of harmful bacteria. It doesn't kill good bacteria.
some bacteria produce toxins in their metabolism which is harmful for humans. if you have used antibiotics, the normal, good, bacteria that live in your body can be replaced by a pathogen, which will make you sick.

Some bacteria are beneficial to humans, and some bacteria are harmful to humans.
Humans should try to be bacteria free.
There are some bacteria that can cause intestinal disease. All humans have bacteria in their intestine but the bacteria is a good thing. One of the most prevalent bacteria in the human GI tract is E. coli. There are different strains of E. coli and not all of them are pathogenic. The bacteria inside the human GI tract is "normal Flora" and is beneficial to humans.
Fungi is a form of bacteria, that is actually sometimes good for your digestive tract.
It has few or no side effects in humans. it kills different types of harmful bacteria. It doesn't kill good bacteria.
monerans are helpful to humans because it is bacteria and bacteria helps humans by making milk yogurt

Yes, it contains some algae bacteria. But it is completely harmless to humans. The Bacteria is actually good for you and is also found in cheese as well.
There are many differences * Bacteria are microscopic while human is not. * Bacteria are prokaryotes. Human is eukaryote. * Bacteria has a cell wall. * Bacteria are the earliest known organisms on earth.
