Unit 2 Exam Reminders

Hi all,

Make sure you are keeping up with your objectives and studying them each night as I keep nagging. The major reason students don’t do well is procrastination.

Here are the upcoming events:

Lab Quiz #2, covering labs 5-8, will be Weds., June 19.

The Unit 2 exam for will be Fri., June 21.

Likely discussion questions include:

1. Under section IB. Virulence Factors that Promote Bacterial Colonization of the Host:

Be able to describe specifically how certain bacteria are able to accomplish each of the following factors that promote colonization and specifically why each provides an advantage to the bacterium.

1. The Ability to use Motility and Other Means to Contact Host Cells

2. The Ability to Adhere to Host Cells and Resist Physical Removal

3. The Ability to Invade Host Cells

4. The Ability to Compete for Iron and Other Nutrients

5. The Ability to Resist Innate Immune Defenses such as Phagocytosis, Complement, and Antibacterial Peptides

6. The Ability to Evade Adaptive Immune Defenses

Two or three of these will be on each version of the exam.

2. Under section IC. Virulence Factors that Damage the Host:

Be able to answer objective #4 under C1a, objective # 2 under C1b, and objective #1 under C1c. These objectives all describe the mechanism for SIRS and are basically the same except for the PAMP that triggers the response and the PRR to which it binds. One of the three will be on each version of the exam. There will be a series of short answer questions testing these objectives.

1. Be able to answer objective #1 under IIB. Ways in which Control Agents Affect Bacterial Structures or Functions

2. Be able to answer objective #2 under IIC. Ways in which Bacteria May Resist Our Control Agents.

Good luck!!
