what kind of bacteria is good and what is bad?
966941
Bacteria living in the human body is basically good. They are considered normal flora (normal inhabitants ) of the human system like E.coli in the human colon which helps in degradation of waste & Lactobacillus which is in the woman's vagina that protects it form other bacteria that is harmful. BUT once these bacteria goes to a part of the body that is not their home (like E.coli that is transferred to the urethra) may cause harm. Like E.coli that causes the UTI. There are a few cultured drinks that has Lactobacillus for good digestion also. Hope this helps. God bless

Characteristics of bacteria? they can cause horribly painful bloody diarrhea!

My best guess would be chlorine.  Chlorine is harmful to humans if its concentrated enough (certainly could be concentrated enough in a chamber), and kills bacteria in water which is why it is used in water distribution.

Not at all.  Some bacteria are beneficial.  In fact, you have some bacteria in you right now that you could not live without.  It lives in your digestive system and helps break down the food you eat.

>>>>Why is distilled water bad for you?\n\nIt isn't bad for you.\n\n\n>>>>What's its effect on lactobacillus (friendly bacteria in your body)?\n\n\nNothing whatsoever. It's water, the same chemical that makes up 95% of the wirrght of the bacteria themselves. It is impossible for distilled water to have any effect at all on gut flora.

Bacteria is a "group noun" (like a flock) for a single type of bacteria. For example "300 e. coli bacteria." (similar to 300 in the flock (flock is singular))\n\nBut when referring to different types of bacteria the noun is typically plural. For example "the the surface of human skin is infested with many bacterias, some harmful, some harmless."  (similar to "the many flocks that we saw flying south for the winter")

think of it as a bacteria...bacteria is a living organism...if you disinfect it will it not die?does bacteria think?does bacteria feel pain and what not?\n\nveggies live off water/sun/nutrients just as we do.veggies begin to rot bebore dead/wasted.\nhumans rot after death...\n\nwhat will you do?\nwhat will you think?

health? . . . diseases and conditions are for infectious bacteris and that sort of fun stuff . . . so i guess health if that helps you.

Antibiotics are not bad for you if used correctly.  They are bad if used inappropriately.  First, all drugs have side effects.  Antibiotics can give you GI symptoms, harm your kidneys, cause allergic reactions, etc.  But the more insidious side effect is the development of resistance.  Every time you use an antibiotic, you are challenging the bacterial flora in your body to a noxious agent.  Bacteria can mutate and evolve into more resistant strains.  What you are in effect doing by taking antibiotics is providing an environment to evolve stronger and more resistant bacteria, and killing off the weaker ones.  This makes treatment of infection more difficult the next time around.

Here is a fairly complete description of differences:\nhttp://www.microbe.org/microbes/virus_or_bacterium.asp\n\nA few notable ones are:  size (bacteria are much larger!), complexity (bacteria are more complex), ability to replicate (viruses require a host to reproduce).\n\nThe body CAN fight off both harmful bacteria and viruses! :-)\n\nGood luck!

Well, let me tell you that all bacteria are not harmful...they are normal flora of our body...exit on skin, intestine, nose and everypart of body....when are immune system goes down, these bacteria multiply and increase in size, some of them produce toxins and infect main organs of body like liver, kidney etc and cause dihrrohea...example is E. coli which is normal flora of instestine causes diarhhoea when immune system goes down...\n\nHope this helps!!!

Bacteria, one-celled organisms visible only through a microscope. Bacteria live all around us and within us. The air is filled with bacteria, and they have even entered outer space in spacecraft. Bacteria live in the deepest parts of the ocean and deep within Earth. They are in the soil, in our food, and on plants and animals. Even our bodies are home to many different kinds of bacteria. Our lives are closely intertwined with theirs, and the health of our planet depends very much on their activities.\n\nMuch of our experience with bacteria involves disease. Although some bacteria do cause disease, many kinds of bacteria live on or in the human body and prevent disease. Bacteria associated with the human body outnumber body cells by ten to one. In addition, bacteria play important roles in the environment and in industry.\n\nWe have all had bacterial diseases. Bacteria cause many cases of gastroenteritis, sometimes called stomach flu. Perhaps the most common bacterial disease is tooth decay. Dental plaque, the sticky film on our teeth, consists primarily of masses of bacteria. These bacteria ferment (break down) the sugar we eat to produce acids, which over time can dissolve the enamel of the teeth and create cavities (holes) in the teeth.\n\nTooth decay provides a good example of how multiple factors contribute to bacterial disease. The human body hosts the bacteria, the diet supplies the sugars, and the bacteria produce the acid that damages the teeth.\n\nCommunities of bacteria form what are called biofilms on many body surfaces. Dental plaque is a biofilm covering the teeth. Biofilms also cover the soft tissues of our mouths and the inner surfaces of our nose, sinuses, throat, stomach, and intestines. Even the skin has bacterial communities that extend into hair follicles. Bacterial communities differ in each region of the body, reflecting the environmental conditions in their specific region. Bacteria that inhabit the surface of the stomach, for example, must deal with extremely strong acid in the digestive juices.\n\nSome regions in the interior of the body are sterile—that is, devoid of living organisms other than the cells of the body. Sterile regions include the muscles, the blood, and the nervous system. However, even these regions face constant invasion by bacteria. The body’s immune system is designed to rid the body of these invaders.\n\nA healthy, balanced community of bacteria is extremely important for our health. Some of these organisms protect us from disease-causing organisms that would otherwise infect us. Animals raised in a completely germ-free environment, without any contact with bacteria, are highly susceptible to infectious diseases if they are exposed to the outside world. Bacteria in our bodies also provide us with needed nutrients, such as vitamin K, which the body itself cannot make. The communities of bacteria and other organisms that inhabit the body are sometimes called the normal microflora or microbiota.\n\nFor the rest of this information, go to:)\n\nhttp://encarta.msn.com/encyclopedia_761574409/Bacteria.html

There are loads to describe. Bacteria and viruses. What are the difference? I can tell you viruses always mutates and could harm you and need cells to depend on while bacteria multiply themselves in the bloodstream and they can harm you but unlike viruses they can also benefit you.

E.\nBecause bacteria can obtain nutrition chemically, they can live in conditions that no-one thought possible, for example in volcanic vents at the bottom of the ocean.
