Artificial snow, remove stains from clothes, food products such as yogurt and cheese and breads. Bacteria are also used in genetic engineering and have environmental applications like: cleaning up oil spills and production of alternative fuels. 4. Viruses are 100 times smaller, live in hosts to survive, and are not alive themselves. 5. A lethal condition caused by a toxin that is released by Clostridium botulinum 6. Relax muscles using a very diluted dose (1/1000). This treatment could help conditions such as Multiple Sclerosis, Cerebal Palsy and Parkinson’s Disease and even stuttering. 7.

It may also give other organisms an opportunity to invade they might not otherwise have. 3. They used Pseudomonas bacteria to “eat” cyanide (a poison), by breaking the compound apart. 4. To understand the genes responsible for growth and disease, we can fight them. From understanding comes new products such as antibiotics, vaccines and industrial uses. 5. Bacteria can whiten paper and reduce the need for chlorine, which pollutes fresh water supplies. Some other points of interest to consider….. - Hospitals are good for treating injuries and immediate problems but are not good places to heal. - Antibiotics can cause harm to organs while they are trying to kill the what is making you sick. - Airplanes are disease factories, so take certain precautions: wear a face mask, boost vitamin C, keep well hydrated, ask to move to a different seat. - “Rub a little dirt on it”
