Summary Introduction

To determine:

  1. Whether a cluster of several million cells would be visible to the naked eye.
  2. With reference to chapter 7, about how long it would take an average bacterial species to reach the infectious dose of a million cells, starting from a single cell.
  3. Why enteric diseases require a relatively higher infectious dose than nonenteric diseases.
  4. Why antimicrobic therapy used on gram-negative bacterial infections could actually lead to illness rather than cure it.

Introduction:

Bacteria are microscopic, so they cannot be seen individually. Different diseases have different infectious doses (which are the number of cells required to start an infection).

Use an example of at least one outbreak in your description. 2. What measures are taken in the United States to prevent outbreaks from occurring? 3.

a. If an egg salad sandwich sitting in a warm car for 4 hours develops 40,960bacterial cells, how many more cells would result in just one more generation?                                                                                                            b. What would the cell count be after 4 hours if the initial bacterial dose was 100?c. What do your answers tell you about using clean techniques in food preparation and storage (other than esthetic considerations)?
Why are Pseudomonas aeruginosa infections difficult to treat? A. Because they form biofilms, which are difficult for antibiotics to penetrate. B. Because they have a special endotoxin that degrades many antibiotics. C. Because we do not have any antibiotics that target P. aeruginosa.  D. Because they are gram-positive bacteria, which are harder to treat.
