Medical Microbiology - SLOs for 2.1 The Microbial World and You

1A. Describe several ways in which microbes affect our lives

• Preventing food spoilage

• Aseptic techniques to prevent contamination

• Replaces bad stuff with good stuff

1B. Recognize the current system of classification and scientific nomenclature that uses 2 names: a Genus/ Specific epithet

• In other words, what rules do these two names have to follow?

• Genus has to be capitalized

• Specific epithet has to be lowercase

• Both names either have to be underlined (if we are hand writing it) or italicized

IC. Differentiate the major characteristics of each group of microorganisms including from classification.

Archaea

• Prokaryote (no nucleus)

• Has no cell walls

• Live in extreme environments

• Unicellular

• Energy: Organic

• Reproduction: Binary Fission (asexual)

Bacteria

• Prokaryotes (no nucleus)

• Has cell walls

• Live everywhere

• Unicellular

• Energy: Organic/Inorganic

• Reproduction: Binary Fission (asexual)

Protozoa

• Eukaryotes (nucleus!)

• Have/ have no cell walls

• Live in water

• Unicellular

• Energy: Organic

• Reproduction: A/S

Algae

• Eukaryotes (nucleus!)

• Have cell walls

• Live in water

• Unicellular

• Energy: Inorganic decay

• Reproduction: A/S

Viruses

• Not eukaryotes or prokaryotes

• No cell walls

• Live in their host

• Acellular

• Energy: Organic

• Reproduction: Replication

Multicellular Animal Parasites

• Eukaryotes (with DNA inside the nucleus)

• No cell walls

• Live in living organisms

• Multicellular

• Energy: Organic

• Reproduction: A/S

1D. Understand the contributions made by key scientists

• Cell theory: all living things are made of cells

• Microscopes

• Vaccines

• Biogenesis

IE. Understand the contributions made by Bacteria

• Recycling of carbon, nutrients, sulfur and phosphorus

• Human health

• Planet’s environment

IF. Understand concepts of normal microbial / resistance, and biofilms

EID: Emerging Infectious Disease

• When a pathogen overcomes the host’s resistance and diseases and increase in incidence

Biofilms

• Attach to solid surfaces and grow in masses (LIKE PLAGUE)

Resistance

• The body’s ability to ward off disease

Normal Microbial

• Prevent growth of pathogens
