Bob the (Bacteria) Builder
This protective outer layer gives bacteria their shape and prevents them from bursting.
What is the cell wall?
This is the scientific term for spherical-shaped bacteria.
What is coccus?
This is the first stage of growth where bacteria get used to their home before dividing.
What is the lag phase?
This type of drug is used to kill or inhibit bacterial growth.
What is an antibiotic?
This term refers to the entire community of bacteria
What is the biofilm?
These tiny, circular DNA molecules are separate from the main chromosomes and often carry antibiotic-resistance genes.
E. coli belongs to this category of rod-shaped bacteria.
What is bacillus?
During this explosive stage, bacteria multiply at their fastest speed.
What is the log phase?
This body part has the most bacteria.
What is the gut?
This term refers to the self-made shield around a biofilm.
What is the matrix?
This whip-like appendage rotates like a propeller to help bacteria swim.
What is flagellum?
This spiral, corkscrew-shaped bacterium causes Lyme disease.
What is spirillum/spirochete?
In this stage, the birth rate equals the death rate.
What is the stationary phase?
It is the process where bacteria converts atmospheric nitrogen into a form plants can use
These are the four things the matrix is made out of.
What are lipids, carbohydrates (or sugars), proteins, and DNA?
Gram-negative bacteria have a thin layer of this polymer, sandwiched between two membranes.
What is peptidoglycan?
Is the following bacteria round, rod-shaped, or wavy?
Lactobacillus acidophilus
What is rod-shaped?
Tragedy! Toxic waste builds up and the bacteria begins to die off.
What is the death phase?
This is ONE way bad bacteria invades the human body.
What is outnumbering/releasing toxins/disrupting?
This is how many more times a biofilm is resistant to antibiotics than single cells.
What is 1000 times?
Unlike eukaryotes, bacteria lack this membrane-bound organelle that houses DNA.
What is the nucleus?
Is the following bacteria round, rod-shaped, or wavy?
Staphylococcus aureus
What is round?
This is the movement of DNA from one living organism to another.
What is horizontal transfer?
This innovative technology uses bacteria to increase structural integrity of this product.
What is self-healing concrete?
These are TWO places were biofilms can be found.
What are wet rocks, kitchen drains, water pipes, ship hulls, and medical devices? (combo of 2)
