Writing Feedback / Essay on the Types of Germs - bacteria [22]
The first type of germ is bacteria, which are defined as "organisms, microscopic in nature; they are unicellular and reproduce asexually." They are an ancient form of life, and most of them have spores that are resistant to dryness. Bacteria consist of single celled organisms. Scientists found a lot of facts after discovering the bacteria. First, different kinds of bacteria can live in high temperatures, icy places and trash. Second, from 500 to 1000 kinds of bacteria live in human bodies; some make disease and others give benefits. Third, there are countries that use bacteria in making cheese, yoghurt and sour dough bread. Fourth, 50% of bacteria produce oxygen. Finally, bacteria can help in cleaning up oil spills.
Bacteria are the most common way of getting diseases. For example, anthrax is "an acute infection disease caused by a bacterium that form spore. A spore is a cell that lie dormant, and comes to life under the right condition ." Anthrax normally come to animal and domestic like cattle, sheep and camel. When a person is exposed to an infected animal, he/she gets this type of disease. In addition, there are many ways to become infected with anthrax such as eating undercooked meat from infected animal and inhaling anthrax spores from contaminated animal products. About 20% of untreated cases of anthrax will result is death. Another examples of bacteria diseases are acne, gastritis, tonsillitis, tuberculosis and kidney infection.
To protect your body away from bacteria you have to wash your hand frequently, as in after going to the bathroom, after entering public place and after handling animal. In addition, try not to touch your mouth, nose and eyes because bacteria come in your body through these organs.
The second type of germ is viruses this type cannot survive and grow. Viruses cannot live for long outside others living cells. For example, they can stay for a short time as few seconds in bathroom and dirty places. Viruses can move from one person to another in high speed.
