 toc How do viruses, bacteria, and protists impact our lives in both positive and negative ways? =Marc=

First of all viruses, bacteria, and protists all have their own pros that can be used to our advantage and cons that can cause problems for us. For example, virus through exstensive research could become a nano-container for medicine that could be directly sent into say a tumor or some specific area that needs medication. On the flip side viruses can cause many diseases some of which can be fatal and untreatable. Bacteria can be extremely useful because they make up foods like yogurt and cheese, can be used to clean up oil spills, can produce fuel such as methane, and can be used to make medicines that can save lives. On the other hand bacteria can be very dangerous in terms of the diseases they bring like the bubonic plague which literally killed millions in Europe. Protists can also cause disease like malaria and other deadly diseases. Overall VBP ’s are mostly helpful and we should appreciate that they exist.

When viruses invade a cell and reproduce they either kill the cell or just leave it alone. When it doesn’t kill the cell, there’s no harm done. However, when they do kill the cell, that’s when you start to feel sick. Bacteria can also cause diseases and make you ill. But bacteria is also helpful. They are decomposers. Decomposers break down large chemicals from dead organisms, into small chemicals, and return the important materials to the soil and water. Bacteria are also found in foods like yogurt. Bacteria can also help your immune system. Once your body has bacteria in it and has reacted to it, then the next time you get the bacteria again it knows how to handle it.

 sorry for the screaming of my sisters. =//**Charlie**//= Bacteria and viruses can be good or bad. But they always have a cause, like some of them that cause harm to organism, their purpose ism't to cause harm to them, but is to reproduce. like viruss they cannot reproduce without a host. Some of the bacterias and viruses cause no harm too. Like some of the virus, the use the host and then leave without harm done. And for bacteria, the might even help us. Some of them help us by breaking down substances/molecules in our intestines that we cannot break down. And some of them even keep bad bacterias out of our intestines. Some of he ancient bacterias can also photo synthesis and produce oxygen for us. Some of them can also clean oil spills and make some medicines like antibiotics. = = Some of the Bacteria cnd viruses cause no harm = = Some bacteria are good and some are bad [] [] = =  =Bryant  = Bacteria and viruses can be both harmful and helpful. They could be deadly or they could keep you alive. Some bacteria cause diseases like botulism and anthrax that have high percentages of death if you get the disease. Bacteria can also //help// us. They decompose things that are dead to richen the soil and help the plants to grow better. They also clean up oil spills, help us digest stuff we cannot digest and change foods into beer, cheese or yogurt. They also keep us healthy. Viruses can also cause very deadly diseases. Although they are harmful, they can be really helpful too. We could take the DNA out of the virus and inject things into the virus so that it could carry it to the places that are infected. Instead of letting the patient take in a lot of the medication, which would have side effects, they could just let the virus go into the patient and inject a small dose into the patient body and it cures the sickness. Protists are good and bad too. They could cause really serious diseases like malaria. They can also help in a lot of other things.  AND Both helpful and harmful Mrs.B: India, where did you find this out? I don't think it is correct. Mrs. B: Beer is actually made with yeast (fungus kingdom), not bacteria. [|back to top] =Timothy= Virus, bacteria, and protests are all either good for us or bad for us. They can be bad when viruses or bacteria carry diseases to us, like the bubonic plague. The bubonic plague is spread with fleas on rodents. The fleas carry bacteria that can harm people. When the organism gets infected, they will start experiencing symptoms swollen lymph glands, heaving breathing, blood vomiting, etc. Eventually, they will kill the organism. If it wasn’t for antibiotics, imagine how the plague could impact our lives! Picture 1 shows how the bubonic plague is transmitted through out the world. They can also impact our lives in a negative way, because in the future, viruses and bacteria can be used in weapons and biological welfare, and that wouldn’t be good when it infects you. You may think that viruses, bacteria, and protists are scary, and you want to avoid them. Think again, bacteria and viruses are all over the world, but viruses and bacteria can also impact our lives in positive ways. Bacteria are found all over the world, they help us in our intestines. They can help break down molecules in our food that we humans can not. They also help us in medicine, producing fuel, methane, environmental clean up/recycling, decomposing, even cleaning up oil spills. Picture 2 shows antibiotic, a medicine that is made bacteria. If it wasn’t for bacteria or virus, we wouldn’t even exist right now. Bacteria, virus, and protists, can impact our lives in so many ways. We should be glad that they exist! like how Bryant included the fact that we can change the virus and make it so it could carry the drugs all over our body. I agree with the fact that he said medicine have side effects, but if you put a tiny dose into the virus, it wouldn't that a bunch of side effects. I also like how he list examples of the things you said. Really interesting answer.
 * India**: This doesnt work...
 * Sofia**: Its like bacteria some harm us but others pay us back by helping like with digesting.
 * India: You didnt talk about Protists,**
 * Sofia:** I like that idea to cure the patient instead of lots of medications, its like a simpler way.
 * India: Protist also can be helpful by the same ways as bacteria, by cleaning oil spills/ recycling.**

Bryant: Yeah I agree to the part where you said that virus and bacteria could be used as a deadly weapon during war or battles. And, of course, we have to be very grateful that they exist, if they did not exist, we would not be able to live! Helen: Good examples. I like how you used an example like bubonic plague. I would like to add that, they are in lots of food you like! :] Evelyn: I like your example of how the disease is carried, but shouldn't there be more than one way? Katherine: You didn't really talk a lot about protists. But the examples are great :D Back To Top

=Helen <span style="font-size: 140%; color: rgb(255, 74, 0);"> = <span style="color: rgb(0, 0, 0);">How do viruses, bacteria, and protists impact our lives in both positive and negative ways? Viruses are good because they provide ways in which scientists can study them and cure diseases caused by them. But basically they are just bad. They cause diseases, anti-biotics don't’ cure or help viruses, they affect the pollution of the environment in various ways, and are very difficult to treat. Some viruses stay with you forever (herpes cold sore is always on the same spot of your lips). Bacteria is good because it’s in lots of food that you eat, like cheese, yogurt, pickles, sour cream, kimchi etc. It’s also in medicine and it helps make vitamins and helps with your digestion system, because it breaks down molecules you can’t digest yourself. They are decomposers, and are used in clean-up. For example, gasoline leaks. And it helps with fuel, because methane/gas is produced by archaebacteria during respiration. But bacteria are bad because they spread diseases. For example tuberculosis is caused by bacterium, but luckily anti-biotics can help a little. Protists are bad, because they cause diseases too. For example, an animal-like protist (protozoan) can cause malaria, because you get it from a mosquito, which is an animal. Apicomplexa, which is a large group of protists, is an example of something bad. <span style="color: rgb(255, 0, 255);">Not only can they get into us and infect us, but because these protist parasites are closer to a eukaryotes cell then bacteria, they are harder to kill then bacterial infections, because those things that will harm the eukaryotes infecting us can also harm the eukaryotes that make up our bodies. (Excellent addition!!! -- Mrs. B) But protists, for example, algae have a number of uses for humans. Seaweed is made up of algae and is a very health meal, it can be made into "green" biofuels, and it makes a great fertilizer.

How do viruses, bacteria, and protists impact our lives in both positive and negative ways? Viruses, Bacteria, and Protists are all related. Viruses can be bad, with spreading disease, but you can also learn from the spreading, and determine more things about prevention and symptoms, and even new diseases. Well a vaccine can be a helpful virus. Also, viruses can be made into empty shells, and you could send in antibiotics/ vaccines to cure the disease. But on a brighter side, bacteria are much better, if they are carrying a diseasse, then it can almost always be cured by an antibiotics. Bacteria are the only living things which can fix nitrogen, and are really good for the environment. Bacteria is in food, it decmposes, it re-cycles, helps our digestive system, is in fuel. It is mainly helpful, and better than viruses. However, it can cause some pretty bad diseases,like Meningitis! Some Proists can be useful! Trichonympha lives in the digestive system of termites and produces cellulase, an impulese that enables termites to digest wood! <span style="color: rgb(255, 0, 255);">Protists also are the bottom of the food chain, and they supply approximately one-half of the world’s oxygen, and Protists, along with bacteria and fungi, are responsible for decomposing and recycling nutrients. (Excellent addition!!! -- Mrs. B) Other chemicals made from Protists are used in treatment of ulcers, high blood pressure, and arthritis! But Some are bad, like some animal-like protists are responsible for diseases such as malaria, amoebic dysentery, toxoplasmosis, African Sleeping Sickness and Giardiasis in humans. And Phytopthana infestans, a water mold, destroyed potato crops throughout Ireland in the 1840s, leading to the Great Potato Famine and the eventual migration of large numbers of people into the United States. <span style="font-size: 140%; color: rgb(255, 74, 0);">sorry, the images wouldnt go on properly, []- meningitus this is a picture of meningitus, a disease that is caused by bacteria [] This is euglena, a protist, that is helpful by treating sewage [] This is the HIV virus, one of the most deaddly viral infections

Well, I disagree entirely with these statements! For Example, If we didn't have Archean-bacteria, then there would be no us! The AB are the ones responsible for the first photosynthesizing and therefore helped create oxygen. Albeit now we have some pretty nasty diseases, we should still be grateful for what the bacteria did before our time and reconsider our stance. Not to mention all the other stuff bacteria does, <span style="color: rgb(0, 9, 255); font-family: 'Arial Black',Gadget,sans-serif;"> <span style="color: rgb(0, 9, 255); font-family: 'Arial Black',Gadget,sans-serif;"><span style="color: rgb(0, 9, 255); font-family: 'Times New Roman',Times,serif;"> Unforgettably, people try and use diseases, like Anthrax, a bacteria to kill loads of people. Like this, We really shouldn't mis-treat them like this.

=Katherine :]= Viruses are basically pretty bad, since they really don’t do any good to us (but some does though). However scientists study them and find things to cute it which is good. For example, scientists can take out the genetic material inside the virus and when its inside you it can carry good stuff around your body which helps. Bacteria actually do more help than harm, bacteria grows in milk to help produce food like cheese, yogurt, sour cream. Bacteria are in pickles and kimchi too! Bacteria in our intestines help us digest food that we can’t break down; some make vitamins that our body needs. They are also decomposers that break down large chemicals in dead organisms into small chemicals, and they clean up Earth’s land and water. Some bacteria likes oil, so scientists use them to clean up oil spills. Bacteria also form medicine that helps produce human insulin for people who have diabetes. Anti biotic helps your immune systems and also kills the bacteria. Protists are okay, they have scary diseases like malaria which may cause death. But they are really cool to study! However people uses bacteria and viruses to kill people for wars. BAD! Image: '[|4023]' www.flickr.com/photos/30522540@N08/3248550082 Back To Top =Alexandre= Viruses, bacteria and protists (VBP) are just a part of life, to be really, extremely honest. Because like what Harry said, the bacteria, Archaebacteria, were able to survive in extreme enviroments, and photosynthesized. Without them, there would be no oxygen, thus bringing not a lot of life to Earth, just a whole bunch of Archaebacteria. And for those viruses, well, in general, when most people catch something they'd say: "Oh no, I've got the virus!" Then that'd spread like wild fire, and give those little microscopic guys a bad reputation. But no, here's what actually happens. The virus puts injects its DNA into the cell. Soon, the DNA controls the cell, making more copies of the virus. Eventually, the virus's copies will overload the cell, exploding it. That's when we start feeling sick. But no, the harmless ones will leave the cell, not causing any harm, and the cell resumes its normal daily um, life. See, if those cells explode, it's bad news for the viruses too. Less copies. So don't trust those 'EVERY SINGLE VIRUS IN THE WORLD IS BAD!' articles. Monkeys behind those keyboards, I tell ya. <<< These little guy's ancestors made oxygen! THANK IT! THANK IT NOW Archaebacteria http://images.encyclopedia.com/getimage.aspx?id=2792724&hero=yes Sofia: Everything has good sides and bad sides.(just saying). Thank you for making oxygen little guy, yea we need them just as much as they need us. I agree with never trust ``a virus is always bad` in articles.

=Sofia= How do viruses, bacteria, and protists impact our lives in both positive and negative ways? Well in positive ways like bacteria are the ones who use photosyntheis to make oxygen and we appeared and could breathe air. BUT, it can also harm you, like the bubonic plague that can kill many people. They gave us oxygen and they could kill us, what else, well they help clean up oil spills, their decomposers(natures recyclers) and help digest food. How about virus, those who give us a cold and chicken pox, but its not on purpose, they just want to inject genetic material into the cell to make more viruses and leave. They´re also are used to cure dieases. So don´t hate them entirely, you´d never be here without them. Small, but deadly AND helpful Back to top

=Evelyn= VBP like we all know isn't all bad. It does helps us. They are simply another peice of life. Without Achea-bacteria there would be no air because they happen to be the leaders of photosynthis! And you know what photosynthies produces? OXYGEN! So with out them then we probably sufforcated a long time ago! So another score for VBP! And about viruses detorying cells. They don't want to destroy cells! They just wanna reproduce! But somethimes acidents happen! They don't INTEND to destroy the cell! Yes. yes I know they cause diseases that I can't find any good out of but, there are cures for most of the dieases! But bacteria is in food! It's in: yougurt, cheese, kinchi, sour cream etc. They arn't disgusting are they? Unless you hate those foods. Oh and I'm sorry if I just disgusted you. But at least we know not ALL bacteria is bad! Check out this cut little protist! I call him.....FISHY! RESPCT HIM! BOW! BOW! BOW!

=William= Did you know that bacteria can turn 64 grams of undistiled styrene oil into 3 grams of even more bacteria? While they are doing so, they create 1.6 grams of biodegradable plastic called PHA. PHA is use to make everything from forks to vitamins. Did you also know that the average person has about 4 pounds of bacteria in their body. Did you also know that you would die if you didn't have the right bacteria in our intestines. Also, bleeding tendensies and scoliosis come from a lack of helpful bactaria in that area. Did you know that the bacteria causes acne can be found on pay phones. Plus, there are 7 different types of bacteria on a locker room shower floor. Bacteria has been able to change dead animals and and plants into coal, which is later used as fuel.
