great question. some are bad but 98% (something like that) are good! Just learned that in school. hope this helps :)
antibiotics are useful against bacteria because they help to kill off the nasty bacteria or they can also stop the bacteria from reproducing - so the illness doesn't get worse. this then gives your body time to make antibodies which will eventually distroy the bacteria. after this, you won't get the disease again because you are immune to it.
It is not safe to eat uncooked frozen chicken that has been left out at room temperature for 13 hours, as it would have entered the temperature danger zone where bacteria can rapidly multiply. Cooking the chicken may not destroy all the harmful bacteria that could have grown on the chicken during that time. It is best to discard it to avoid the risk of foodborne illness.
In the digestive tract are bacteria, the most famous of which is Lactobacillus acidopholus, which aid in digestion, compete with possibly virulent bacteria that are inhaled on a daily basis, synthesize vitamins, convert dietary fiber, and degrade toxins. There are more bacteria in the large intestine than there are cells in the human body. The bacteria also aid in developing a vigorous immune response; more than half of the body's immune tissue is located in the lining of the small intestine. All of the digestive tract bacteria are discharged from the body daily and renewed without causing disease. Antibiotics actually end up depleting the intestinal flora leaving a person susceptible to other infections. Staphylococcus epidermidis and P. acnes are two bacterial species that are naturally present on the skin; Streptococcus mutans is present in the mouth. These bacteria species can cause infection, acne, or dental plaques if not kept in check, but also compete out more virulent species of bacteria. Eliminating these colonizing species altogether would leave a person vulnerable to more severe infections.It seems likely, however, that most people know bacteria best because of the diseases they cause. Some of these diseases are produced when bacteria attack directly the tissues in a plant or animal. For example, fruits and vegetables that become discolored as they are growing may be under attack by bacteria. Bacteria also attack organisms by releasing chemicals that are poisonous to plants and animals. Such poisons are known as toxins. A familiar toxin-producing bacterium is Clostridium tetani, responsible for the disease known as tetanus. Tetanus is a condition in which one's muscles are paralyzed, explaining its common name of lockjaw. A related bacterium, Clostridium botulinum, releases a toxin that causes the most severe form of food poisoning, botulism. Some forms of dangerous bacteria live on the human skin, but cause no harm unless they are able to enter the blood stream through a break in the skin. Among these bacteria is Staphylococcus, responsible for the potentially fatal toxic shock syndrome. And although E. coli is helpful within the digestive system, if it is ingested and enters the bloodstream it causes severe cramping, diarrhea, and possibly even death. Most forms of food preservation, such as freezing and drying, are designed to kill or inactivate bacteria that would otherwise damage food or cause disease. One of the most common methods of destroying bacteria in foods is pasteurization. Pasteurization is the process of heating a food product to a particular temperature for some given period of time. The temperature and time are selected to be sure that all bacteria in the food are killed by the process. The pasteurization of milk has made it possible to insure safe supplies of one of the most popular of all human foods. http://www.scienceclarified.com/As-Bi/Bacteria.html
Probably not but eating raw meat can almost CERTAINLY make you sick & expose you to Parasite's. Eat responsibly & work out, don try stupid fads & silly stuff, those almost always do more harm that good.
Drinking your own blood is not recommended as it can introduce harmful bacteria or viruses into your body. Additionally, consuming blood can lead to iron toxicity. If you are bleeding, it is important to seek medical attention rather than attempting to drink your own blood.
Yes. Most bacteria is not harmful to us such as bacteria in a yogurt, but some bacteria is harmful.
Only 1% of bacteria is harmful to humans
Harmful bacteria will harm you. Helpful bacteria will help you.
the harmful bacteria live in air,human body etc.
Bacteria can make you get a harmful diseese, and you could dye. ( I think )
harmful
There are harmful to all organisms, but some bacteria are helpful in many ways.
Some common harmful bacteria include Escherichia coli (E. coli), Salmonella, Streptococcus pyogenes, and Staphylococcus aureus. These bacteria can cause various infections and illnesses in humans.
a bacillus bacteria
Bacteria in storm water can definitely be considered harmful. This is because this bacteria is hard to kill and foreign to your body.
Bacteria can be both harmful and helpful. Harmful bacteria can cause diseases in humans, animals, and plants. However, some bacteria are beneficial and play important roles in processes like digestion, nutrient cycling, and decomposition.
All Microbes are not harmful. All virus are harmful. Some bacteria are harmful
