What is the Cell Theory?

• Something can arise from nothing.

• Pathogens can cause disease.

• All living things are composed of cells and come from preexisting cells.

• Microbes have been on earth for 3.5 billion years.

What is a pathogen?

• A microbe that does not cause disease

• A microbe that causes a disease

• A reference for identifying organisms

• A substance used to stimulate the production of antibodies and provide immunity against one or several diseases.

Which is not a cause of an Emerging Infectious Disease?

• Changes in population

• Pathogens become resistant to antimicrobial medications.

• Increased travel and immigration

• Classifying and establishing scientific nomenclature for microorganisms

What is Taxonomy?
