Prokaryotic Microbe Lecture Materials
These
are the Prokaryotics: Meet the Microbes Lecture materials of the Virtual Microbiology Classroom. The resources below are used to supplement an actual
college microbiology course. Anyone taking, teaching or interested in
biology may find these materials helpful and is welcome to use them.
The Prokaryotic Microbes lecture materials include:
- a list of learning objectives
- a PowerPoint lecture
- a prokaryote classification homework assignment
- additional required readings
- practice test questions
- review questions
- photos of prokaryotes and prokaryotic colonies
- links to additional educational resources
LEARNING OBJECTIVES
These lecture learning objectives are a study guide based on the VMC Prokaryotes: Meet the Microbes Lecture PowerPoint Show:
- Understand the three types of Archaea that we discussed.
- Know the three levels of hierarchy in biological classification (out of the nine we discussed) are we mainly going to be referring to in this class.
- Understand the difference between Gram-positive and Gram-negative bacterial cell walls.
- Know the information presented on the Gram-positive bacterial genera and species that we discussed.
- Name and describe the bacterial genera that produce endospores. Are they Gram-positive or Gram-negative?
- Which species of bacteria are considered Gram-variable? Why?
- What is different about the cell wall structure of acid-fast bacteria when compared to the Gram-positive bacterial cell wall?
- How is Blood Agar (BAP) useful in distinguishing between the pathogen Streptococcus pyogenes and normal flora?
- Know the information presented on the Gram-negative bacterial genera and species that we discussed.
- How is MacConkey's agar useful in identifying different types of Gram-negative bacteria?
- Describe the important differences between encapsulated and unencapsulated Haemophilus influenzae.
- How is the life cycle of Chlamydia different than that of most bacteria?
LECTURE POWERPOINT
Versions of Prokaryotic Microbe PPT:
- Student's Prokaryotic Microbe PowerPoint Show
- Student's Prokaryotic Microbe PowerPoint PDF Printout
Fill-in-the-Blank Format:
All of the lecture PowerPoints used in the Virtual Cell Biology Classroom are fill-in-the-blank format to encourage students to pay attention and follow along during the presentation.
Printing:
The best way for students to print out the PowerPoint Show is to download the PDF version. Select Print, and, when the Print screen comes up, go to the Print Handling options. Under Page Scaling, select "Multiple pages per sheet", Under Pages per sheet, select "2". That uses up less paper, placing two slides on each page.
PROKARYOTIC MICROBE HOMEWORK ASSIGNMENTS 1 & 2
1. Bacteria Classification Spreadsheet Study Aid: Build this spreadsheet throughout the semester, to use as a learning tool as the course introduces more types of bacteria.
2. Prokaryotic Monsters Inside Me Homework Assignment: This assignment is based on material from Animal Planet's "Monster's Inside Me" show. Watch the video clips linked below then complete the related homework assignment.

- Hospital Fight to Stop Superbug's Spread Talk of the Nation Radio Story
- Radiolab "Patient Zero" Podcast
REQUIRED READINGS
Here is what you need to read, in addition to the PowerPoint, to master this topic. Check Moodle & your textbook for additional readings.
- Gram Stain: Differential Stain for Gram+ & Gram- Bacteria Identification
- Acid-fast Stain: Identification of Mycobacteria & Nocardia
- Endospore Stain: Differentiating Endospores from Vegetative Bacterial Cells

On 9/18/12 the National Public Radio (NPR) show Talk of the Nation featured a story on superbug antibiotic resistant strains of Klebsiella pneumoniae: "Hospitals Fight To Stop Superbugs' Spread". This is important information on scary new bugs and what healthcare institutions are doing to protect their patients and employees.
