As a microbiologist, although i'm believe that microbes are very useful in our daily life but the pathogenic microbes can make us suffer.. last month i was infected with food poisoning and this month with the communicable diasease until i had an off-key voice.. ;-( because of fever, bad caugh and painful sore throat.
A communicable disease such as a cold is a disease that spreads from person to person. Communicable diseases are diseases that you can "catch" from someone or something else. When a person becomes sick with a communicable disease it means a germ has invaded their body.
Germs are tiny organisms (living things) that may cause disease. Germs are so small and sneaky that they creep into our body without being noticed. In fact, germs are so tiny that you need to use a microscope to see them. We don't know what hit us until we have symptoms (runny nose, cough, sore throat, fever, etc.) that let us know we've been attacked!
Germs are microbes. A microbe is a tiny living organism that can only be seen with a microscope. Microbes are the smallest form of life on Earth. Microbes have existed for millions, and possibly even billions of years. Although some microbes can make you sick or may even kill you. most are harmless, and some are extremely helpful.
Let's me just talk about bacteria. Bacteria are EVERYWHERE! They live in sub freezing cold temperatures and boiling hot temperatures. They live up high in the sky and down deep below the ocean. In fact scientists have found colonies of bacteria thriving 1,600 feet below sea level without oxygen or sunlight. Scientists also think there are signs of microbial life on Mars!
Have you ever heard of people becoming sick after eating undercooked hamburger? The bacteria that can invade your body if hamburger is tainted with bacteria and not cooked thoroughly is E. Coli. E. Coli is a bacteria that can cause people to become very sick and possibly even kill them. Another common bacteria associated with food poisoning is Salmonella. When this bacteria is eaten it causes nausea, vomiting, abdominal pain and diarrhea.Did you ever become sick with sore throat? Sore throat is caused by a common type of bacteria called Streptococcus. Strains of streptococcus that cause throat and skin infections lurk worldwide and spread by touch or through the air. Streptococcus is usually not fatal and can be treated with antibiotics. I went to a clinic yesterday, so now i have to take a lot of medicine including the antibiotics.
Remember that ALL Bacteria are not bad. Some bacteria are good for our bodies, they help keep things in balance. TQ to these tiny warrior because make me realize the important of healthy body!
