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 diges…t 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. ( Full Answer )
Answer . That would be antibiotics. Antibiotics work with your immune system, reving it up, so it can kill batcerias in case of, per example, bronchitis or a strep in your throat.. Topical antibiotics will also work on skin for cuts and such to prevent infection.. However, you should not forge…t that antibiotics will also kill GOOD bacteria in your system, such as the ones in the digestive system and in a woman's vagina.. There is a wide range of antibiotics that can be taken in pill form, and, as far as I am aware, they are only available through a prescription from your doctor. Some mild topical antibacterial cream are however available in pharmacies. Antibiotes In 1928 Alexander Fleming found a medicine that can kill bacteria he got it from mould. . Antibiotics.

It causes infectious diseases... and is it a bad for the animals and the wold and the humans and entire too
bacteria can be very harmful or it can be benificial (unharmful) i am currently studying micr oranisms and microbes and i am only 10 years old and dont know very much yet Some bacteria are harmful and some are essential to animal life.
In general there are two ways that bacteria can be harmful: . By feeding on human body cells directly. . By feeding on some other substrates but at the same timeproducing some waste product that are harmful to humans.
Some bacteria are harmful, and these bacteria are called pathogens; common examples include Salmonella typhus and E. coli O157:H7 . However, many bacteria are neutral to humans - they do not help us, but they do not cause disease. There are thousands of species of bacteria living in the soil, o…n and in plants and throughout the world that never impact humans directly. Also, there are some classes of bacteria that are helpful to humans, including the microbiomes in our intestines that help us digest our food and the microbiome on our skin that protects us from all sorts of nasty skin infections.

No. Bacteria is part of our existence. We need bacteria in our daily lives. Bacteria are both harmful and useful to the environment and animals, including humans.
Yes !. Beneficial bacteria are everywhere. They are in the food that we eat, the air that we breathe and the water that we drink. They appeared on earth over 3.7 billion years ago and have colonised virtually every environmental niche since. To date, approximately 4,000 species of bacteria are know…n to man but it is thought that there are many millions that remain to be identified. Bacteria are found in the coldest, hottest, driest, wettest, deepest and highest places on earth. They can survive in the most acidic, alkaline and salty of environments. They can eat virtually anything from dead bodies to car tyres. They have been found growing in toxic waste dumps and sites contaminated by radiation. They can help certain plants grow by accumulating nitrogen from the atmosphere. They are involved in the production of various foods and beverages like yoghurt, cheeses and wine. Without bacteria there would be no degradation. We, as humans, cannot live without them. Our bodies are covered in billions of bacteria (normal flora) that provide us with nutrients that we cannot supply ourselves and they help us digest our food.. Like every living thing on earth, it is of vital importance for bacteria to reproduce and pass on their genetic information to the next generation. Many bacteria do this in harmony with their environment by existing in a free-living or parasitic form. Of the parasites, only a very small portion of them actually cause disease and this characteristic can actually be seen as a failure of the bacteria to adapt to its environment. ( Full Answer )
Bacteria live everywhere in the air, in soil, in water, in food, and on every sort of plant and animal. They live inside our bodies and, while some bacteria are harmful to humans and other animals because they can cause disease, we could not live without them. They make our digestive systems work an…d help eliminate waste from our bodies to keep us alive and well. Only certain bacteria are harmful to us, and these can pretty well be controlled by cleanliness, including frequent hand washing and being careful not to release disease-carrying bacteria by sneezing, coughing, or spitting.

babykitty hellokitty, really why would i put that im a girl an di finger myself and i like it it feels so good and i did it to another girls n got them pregnant
It depends how you look at it. Certain types of bacteria are used in a good way, to make yogurt and other dairy products and are part of the sewage treatment process. They are also used to make medicine and are part of biotechnology. Unfortunately, they can also cause infections and deadly illnesses… like anthrax, cholera and tuberculosis. ( Full Answer )
We're sorry this site is unable to answer this question either there are problems with this site or the site is just being stupid, so it would be best if you didn't look here. Thank you have a nice day.
Some can. One thing that can happen, is that if your immune system is fighting one infection, it can leave you vulnerable to a second one. Some bacteria have been discovered to produce chemicals that destroy immune cells in order to defend themselves.
Some bacteria have reached a symbiotic relationship with their hosts. Examples include: Komodo dragons - they have bacteria that live in their mouths but do not make them sick - the dragon bites a victim and even if the victim escapes after one bite, in general in about a week the weaker orga…nisms (deer etc) die from septicemia - leaving a corpse for the dragon to find and eat. Humans - our lower intestinal tracts have loads of e. coli bacteria - the stuff that makes us sick if ingested (from unwashed hands and offal.) What does it do? Produces vitamin K2, helps with digestion of some foods and keeps other bacteria from taking over in there. Bacteria also help in breakdown of dead materials (plants and animals) and help recycle the elements beck to the food supply. ( Full Answer )
Some bacteria help us digest food, other bacteria live off our bodies and can kill you. this is one example of a much much more complex system than i can hand down over wikianswers.
The term pathogen is derived from the Greek ÏÎ±Î¸Î¿Î³ÎÎ½ÎµÎ¹Î±, "birth of pain." or "that which produces suffering" and that's basically what a pathogen is. It is an agent that causes pain and suffering to its host through disease or illness. Put more simply, a pathogen is anyt…hing that causes a disease. The agents that cause these diseases are infectious microbes (more commonly known to people as germs or bugs) such as bacteria, viruses, fungi and parasites. There are many different types of these agents and not all of them are infectious or harmful. In fact the majority of them are harmless and some even beneficial. Therefore it is important to remember, that pathogens refer specifically to those agents that can cause disease, illness or harm to its host. So yes, in answer to the question. pathogens are harmful bacteria (but not just bacteria) that cause disease. ( Full Answer )
Bacteria can be harmful to the body if the species of bacteria is aharmful one. It can cause food poisoning, infect wounds, andpollute water. Some harmful types of bacteria are MRSA, E. Coli,and gangrene.
Yes. Your skin has many types of bacteria that are needed to fight off more harmful bacteria. Females have bacteria that help fight off fungal infections. When a bacteria population reaches a certain number it is no longer helpful, and thus considered pathologic
There are many, many types of bacteria. They can be both harmful and helpful to us. Also, even if there were to be helpful in a certain part of the body they may also be a pathogen in another.
some harmful effects of bacteria include: can cause decease's, sickness, unusual behavior in victim, spoil food. But there are many more.
It depends of what kind of bacteria it is, if it is almost 99% thanit is good but if it is below 50% than it is bad and can eithermake someone sick or it makes them die.
yo mama just kidding the viruses hold on to the host and get the bacteria to go away slowly
Yeast, a bacteria found in bread, yogurt and chees (I think) is not harmful - why would we eat it if it was?\n. \nYeast is the bacteria that helps bread rise when it is baking.\n. \nThe overall answer:\n. \nNo, the bacteria is NOT harmful \n. \n A2: \n. \nThis bacteria is acually good for f…emales.

Most bacteria are harmful because they release chemical poisons called toxins into the body that damage cell structure and function
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). ( Full Answer )
Bacteria can be harmful to people because it can cause serious sickness to the body, and if bacteria is reached by other harmful diseases that you have like eczema's skin disease) bacteria and sun rays work together to make their skin itchy, dry, and flaky The bacteria also works as a eating away pr…oduct that is almost like swimming in a lake with leaches. Its eats away at your skin and insides to cause the common cold, and could be fatal when putting bacterialized substances into open cuts, the mouth, nose, and eyes. This harmful stuff also isn't easy to take out, or get rid of, because it can stay into your body for months, years, and possibly forever causing you to have a possible defect sickness. Dr.Whitmman . Thank you... . ( Full Answer )
great question. some are bad but 98% (something like that) are good! Just learned that in school. hope this helps :)
Yes. Most bacteria is not harmful to us such as bacteria in a yogurt, but some bacteria is harmful.
I'm sure you know that it can be both like the E.coli bacteria that lives in your colon is helpful, but if it grows uncontrollably you can develop a disease so i would say that they are more harmful than helpful
streptocaucus and staphyllocaucus also poliamyellitus + pneumcoccus . this was actually for my science HW
There isn't really a "purpose" for harmful bacteria, or anythingelse, in the scientific sense (perhaps what you really meant to askwas "Why did God/the gods create harmful bacteria?" but then youshould have put it in the Religion category). Some bacteria are "harmful" because that helps them spread… andreproduce (bacteria that happened to cause coughing or sneezingspread more effectively, and so passed that trait on to theirdescendants). Some bacteria are harmful as a defense against otherkinds of bacteria; a species that can live in a highly toxicenvironment has at least some incentive to MAKE the environmenthighly toxic so that they don't have to compete with other species.And some bacteria are harmful more or less "by accident"; theydon't derive any real benefit from being harmful, but there's noadvantage to them in NOT being harmful either, so there's noevolutionary pressure on them to become either more or lessharmful.

Very few bacteria cause illness And some bacteria are used to make food such as cheese and yogurt.
It touches the man in places where no man should be touched...... THE NASAL CAVITY!! :O
Actually, most bacteria is good for your body at a certain point- it all depends on the type of bacteria. Some types help build up our body's immune system.
Just about any - gram negative, gram positive and acid-fast are all known to have pathogenic bacteria within them.
bacteria is not all harmful in actuality bacteria actually live inside of you the bacteria in your stomach make vitamins for your body which are essential for your survival. That is why after taking antibiotics you must east yogurt because yogurt has live bacteria in it that replace the good bacteri…a you lost from the medicine ( Full Answer )
Bacteria are alive, can be helpful and most are harmless. That's right, one type of these tiny single celled critters dwells in your gut, assisting in digestion of food. There exists however, harmful types of infectious bacteria that have the potential to make you feel extremely unwell. These pup…pies can reproduce with lightening speed, and potentially release tissue damaging toxins ( Full Answer )
bad bacteria makes you sick if inhaled or ingested, so people come in contact if they don't wash their hands before eating, touching their face, biting nails (anything that allows hands to contact the mouth, nose, eyes) also if someone is around an infected, contagious person: infectious coughed u…p droplets may be inhaled and absorbed into the other person's lungs.

Bacteria can be helpful by forming food compounds and fightingdiseases. But they can also make us ill when it's get high
Bacteria would consider benefitial and harmful bcz many food component are you eating made by bacterial reactions like yeast... but most of spp. are harmful.
When we think of bacteria there 2 types. The saprophytic(decomposers) and the pathogenic(bacteria that cause infection). Bacterial diseases in the past have killed many people, example - Tuberculosis(caused by a bacterium called mycobacterium tuberculosis or by a bacterium called mycobacterium Bovis…), nowadays there are many antibiotics to prevent such diseases and so large numbers of cases have drastically dropped. Yet bacterial diseases still exists(like cholera which is caused due to a bacterium called salmonella) specially in poor countries and people get infectious diseases(diseases that spread from one person to another). Even STD (sexually transmitted diseases) caused by bacteria still exist, example - Gonorrhoea(caused by the bacterium Nisseria). Hope this helped :) - Hasith Dissanayake.... ( Full Answer )
Yes. Most bacteria is not harmful to us such as bacteria in a yogurt, but some bacteria is harmful..
Both, there are good bacteria to help make you better and there are bad bacteria to make you sick. That is where the common cold comes from.
Some types of bacteria can be harmful to us but some are actually quite useful and without them, we wouldn't be able to digest things. Cheese and yoghurt are made using bacteria and so is penicillin. Some can be bad such as some strains of E. coli, which can cause vomiting and diarrhea.
They usually begin to reproduce at an early age and have largequantities. They usually won't care for them as much or protectthem.
The acid in your stomach is a Bacteria, digesting your food and keeping you alive. But other Bacteria come from outside your body, entering from the nose or mouth, making you sick. But only Bacteria can be cured, not viruses. So there are Good Bacteria that keep you alive, and others that try to kil…l you. ( Full Answer )
There is more than one kind of bacteria which may inhabit the human intestines. There are bacteria (such as lactobacillus acidophilus) that are beneficial to human health, and help us to digest our food. Other types (such as cholera) cause illness. .
Some bacteria do, but most don't. Vitamins are used by multicellular organisms for signalling and to modulate nutrient uptake and the immune system; the bacteria simply keeps its own cytoplasm clean without the need for vitamins.
The bacteria 'normally' present in the colon are not harmful, unless immunity is lowered. You call them commensals. Means harmless. But there importance in the body is recognized once they are killed by broad spectrum antibiotics. You get the super-infection by Clostridium difficile of Candida albic…ans. Then your life is endangered. Unless you get it treated by metronidazole 400 mg thrice a day for 3 to 5 days in adults. And suspension metronidazole in children according to body surface area. ( Full Answer )
It depends what kind of bacteria you're talking about. Our bodiesnaturally contain bacteria that helps us digest food.
