This preview shows page 2 - 6 out of 31 pages.

Emerging diseases→ a disease that suddenly becomes prevalent meaning it is increasing in incidence or geographical range. (ie swine flu, Lyme disease, Hepatitis C, SARS, AIDS, Mad cow disease, West Nile encephalitis) Due to: Resistance to antimicrobial medications (ie tuberculosis, malaria) Increased travel and immigration (ie malaria, cholera) Changes in population (i.e elderly, HIV/AIDS) Bacteria may cause chronic diseases (i.e H. pylorI) Re-Emerging diseases→ diseases that were previously in check and under control but are now becoming prevalent mostly due to uncompliance in vaccination and antimicrobial resistance (i.e measles, mumps, whooping cough 2
UNIT 1-Module 1-Ch1,3: Humans and the Microbial World, The Molecules of Life, Microscopy &Prokaryotic Cell StructureDefine the term normal microbiota. The collective term of the normal flora or microbes found in the surfaces of the human body Identify the roles of the normal microbiota in maintaining human wellness.

UNIT 1-Module 1-Ch1,3: Humans and the Microbial World, The Molecules of Life, Microscopy &Prokaryotic Cell StructureMovement Motile Non-motile Motile State the principle distinguishing features between the six types of microbes including bacteria, fungi, protists, helminths, viruses, and prions.Construct a Venn diagram representing the structural relationships between the six types of microbes. 4
UNIT 1-Module 1-Ch1,3: Humans and the Microbial World, The Molecules of Life, Microscopy &Prokaryotic Cell StructureCompare the relative sizes of the six types of microbes. Eukaryotes are larger than prokaryotes which in turn are larger than viruses Explain how the scientific name of an organism is written. Uses the binomial system of nomenclature. They are always italicized or underlined.
