Bacteria... GOOD?!



Bacteria can be found in so many different places on Earth. They are found in cold, hot, wet, and dry environments. Some bacteria are good for you, and some are bad.




Can you think of some examples of GOOD bacteria?
If you said "yogurt", you're right! Bacteria is used in making yogurt... Read the label and you might be able to see the genus and species name of the bacteria in your yogurt. YUMMM! :)




Can you think of some examples of BAD bacteria?
E. coli is a type of bacteria that can cause deadly food poisoning.
Staphlococcus aureus is a type of bacteria that causes a horrible infection known as a "staph infection".

Strep throat is caused by a bad bacteria called STREPTOCOCCUS PNEUMONIAE. Check out Streptococcus pneumoniae in action:




*REMEMBER*: Not all bacteria are bad. We try to "sanitize" in the effort to kill all bad bacteria but sometimes we are killing good bacteria that we need in order to survive. The good bacteria eat viruses and microorganisms that make us sick.
