Bacteria is all around us, in our bodies and on our bodies. It is in part that these natural flora keeps us healthy. They do this in one way by out-competing other harmful bacteria for nutrients. If the harmful bacteria cannot get nutrients for food, they cannot survive.

Does having bacteria in your bodies make us sick?

no, unless you have a lot of bad bacteria in your body then yes


How is bacteria useful to us?

This is a multifaceted subject. Concisely stated, we CANNOT survive as a species without bacteria. They are all around us and ON us. Bacteria living on our skin protect us from external pathogens by fighting off virulent agents, e.g. harmful bacteria that can cause skin infection, fungi, parasites. They also maintain healthy skin pH levels. The bacteria in our digestive tract also protect us from pathogens, aid our digestion, and they also participate in the synthesis of various vitamins. These bacteria in and on our bodies are symbiotic (we are mutually beneficial to each other), and they are ESSENTIAL for human life. Aside from that type of bacteria, other types are used industrially: food production (cheeses and other foods requiring fermentation), alcohol production, creation of certain medicines, etc.


Why are bacteria unable to live in our bodies?

Bacteria do live in and on our bodies, in fact we could not live without the bacteria that live symbiotically in our gut helping us digest foods and forming the majority of the mass of our feces. However there are many places in our bodies where bacteria can harm us when they live there, causing diseases. Our immune system attempts to track down and kill bacteria (as well as viruses, parasites, fungi, etc.) in those places and limit the damage. One part of the immune system reacts as a "generalist" attacking all unknown foreign cells that it does not recognize as "self", another part of the immune system reacts as a "specialist" learning what has attacked us and preparing to fight that in the future when it is encountered again. This "specialist" portion of the immune system can be preactivated by vaccination to prevent disease.


How bacteria effects food?

Answer:We could not live without the protective bacteria on our bodies and in our bodies. We have over 50,000 bacteria per square inch on our skin and if you use a scrub brush to wash the skin, you can remove this protective bacteria and skin disease will follow. Our stomach used bacteria to digest food and without it, we would not survive. Human feces is approximately 67 percent undigested food and bacteria and these mentioned are useful bacteria. The bacteria we pick up from the pay phone or from the door handle in the local public restroom are harmful because they are foreign to our bodies and can make us sick. Other avenues or bad bacteria is from other human contact, such as shaking hands or a casual kiss. To keep these at bay, wash your hands often with an antibacterial soap to keep the bad bacteria from entering your body.Answer:Certain bacteria can harm humans by 1) while growing, they destroy tissue and 2) by releasing toxins that poison humans.

What organizations exist to help protect you when you are far from home How do they protect What do they do?

On our skin and even inside our own bodies, like the digestive tract, we have bacteria, considered to be our own micro flora, these are bacteria picked up in our environment that protect us. If you are away from home sometimes, because we are not normally exposed to some types of bacteria our micro flora may not be effective. But it is possible to get immunizations, that will help our bodies build up antigens to protect us.
