Open Ended

True or False? Microbes only live in dirty places. Explain your answer.

Microbes literally live everywhere!

...even on clean surfaces

Open Ended

True or False? All microbes cause illness. We would all be healthier if they did not exist. Explain your answer.

Not all microbes are bad!

• Only a small percentage of microbes make us ill.

• Most microbes are harmless

• Many types of microbes are essential for ecosystems and our health!

Multiple Choice

Which statement uses the correct terminology?

• Only a few strands of E. coli can make a person sick.

• Only a few strains of E. coli can make a person sick.

• Only a few species of E. coli can make a person sick.

​Species vs. Strains

• ​E. coli is short for Escherichia coli.

• ​E. coli is a species of bacteria.

• ​Members of a bacterial species with small differences in genetics are called strains of that species.

• ​Most strains of E. coli are harmless and are necessary parts of out digestive systems.

• ​Only a few strains of E. coli can cause illness.

• ​Some people mispronounce the word "strains" as "strands." Please do not be one of them

• Antibiotics are only effective against bacteria.

• But the cold and flu are caused by viruses.
