What is the skin?
Drug resistance in a bacterial population initially originates from these random changes in DNA.
What are mutations?

These white blood cells specialize in engulfing and digesting invading bacterial pathogens.
What are macrophages?
Patients are instructed to finish their full course of antibiotics to prevent these tougher, surviving organisms from multiplying.
What are drug-resistant bacteria?
This long, whip-like appendage propels many bacterial cells through liquid environments.
What is a flagellum?
These four experimental steps are used to demonstrate that a specific microbe causes a specific disease.
What are Koch's Postulates?
This substance formed at an infection site consists of dead white blood cells
What is pus?
Taking antibiotics will not cure the common cold or flu because these illnesses are caused by this type of pathogen.
What are viruses?
