Bacteria are helpful to us in many ways. For example, have you ever got a chicken pox vaccine? They actually inject you with the disease so your immune system can create a cure. That's why you will probably not get the same thing twice. Also, bacteria aid in making things like chocolate, cheese, yogurt, and bread.
fyuck you
The question is toxic to what. Not all chemicals which are toxic to humans are toxic to bacteria, and some chemicals which are toxic to bacteria are harmless to humans (which is why we can have antibiotics). There are chemicals (like Hydrogen Sulfide) which are very toxic to mammals that SOME bacteria eat as food. But there are other chemicals like chlorine which are toxic to both humans and bacteria. So the question does not have a simple answer.
Sometimes bacteria can be helpful. If we didnt have bacteria we wouldn't have some medicine or cheese or yogurt etc.
Probably to humans, I wouldn't eat dead leaves. Well yes you wouldn't eat dead leaves but in an eco way they are helpful.
I know 2 bacteria, useful and harmful: E.coli, harmful Salmonella, harmful B. Animalis(Bifidobacterium Animalis), helpful Phytoplankton(not a bacteria, though), helpful
Humans are related to bacteria in that they are both a part of the Earth. They interact with one another, and while some bacteria is actually helpful to humans, many kinds of bacteria can be harmful.
some bacteria can be very helpful. There is bacteria that are in human's intestines and they help in digestion. There is also friendly bacteria such as intestinal flora and micro flora which release helpful vitamins.
Bacteria, dinosaurs, and lava are some examples

Some viruses target bacteria or fungi, which can be harmful to humans. These viruses are called "bacteriophages" or sometimes just "phages".
Some bacteria are beneficial to humans, and some bacteria are harmful to humans.
This is not entirely true. It is shown that Yeast is not a form of Bacteria Yeast is in the Kingdom Fungi, therefore it is a type of fungus. Some helpful bacteria is yeast.

Bacteria may be harmful or helpful to humans. Some bacteria may cause lethal diseases when infecting humans, whereas others may be necessary to help maintain optimal health in humans (such as those in the small intestine which produce Vitamin K). Other bacteria help us with the production of various foods (cheese) and beverages (beer and wine).
