This week will be devoted to learning and understanding some basic concepts in
microbiology. Due the very small size of microbes and the potential for accidental
transfer of these organisms in the laboratory, we will focus our attention on discussing
one of the most importnat tools in the microbiology lab: The microscope.
Thanks to Anton Leeuwenhoek’s curiosity and his work with lenses, the compound
microsocpe was created. This is by far the most frequently used microscope in the
microbiology lab but it is not the only microscope that is utilized.
Perform some research and share with the class a clinical scenario that relied on a
certain type of microscope to make an accurate clinical diagnosis. Establish the rationale
for selecting a certain type of microscope and what your second choice may be. Be sure
to substantantiate your choice and how your microscope contributed to identifying the
specific pathogen.
Remember that perfomring an accurate microscopic examination requires learning and
practice in using this important tool.

HAVE STUDENTS WRITE THEIR PATHOGEN PAPER IN
THE DISCUSSIONS THROUGHOUT THE SESSION
Week 6 Pick Your Pathogen Paper requirements:
Choose a newspaper article and summarize it (week 1)
Use the TEXTBOOK or other sources to describe the taxonomy and features of the chosen microbe
All the following criteria are met:
1) Paper includes supporting details and/or examples from lecture material and/or text
2) The following should be included:
•
•
•
•
•
•
•
A.) morphology (discussion week 1), cellular characteristics (discussion week 2), and
gram stain (discussion week 1) characteristics, virulence factors (discussion week 2),
b) susceptibility to antibiotics (discussion week 4),
c) host cells, nutritional needs, growth conditions (discussion week 3),
d) how it evades the immune system and mode of invasion into the host(s) (discussion
week 5)
e) interactions with the hosts and diseases caused and body systems that are affected
(discussion week 5)
f) symptoms when the pathogen infects a host (discussion week 6),
g) diagnosis and therapeutic intervention needed (discussion week 6)
3) Connection to the health/nursing field made (discussion week 6)
Abstract: Week 6
Post the following in the discussions as initial post or follow-up options for students. Provide specific
feedback to students each week. Students can submit the completed papers by Sunday of Week 7
(before the final exam).
WEEK 1: MICROSCOPY
Choose a pathogen to research this session (see Week 6 Pick Your Pathogen assignment) and locate a
newspaper article about the pathogen or a disease it causes. Summarize the article in 6-8 sentences.
What staining and microscope is best used to see that pathogen? What would your microorganism look
like (morphology)? Your response should be a minimum of 5-6 sentences (100-200 words) and include
specific references from Edapt, lecture, or the textbook.
WEEK 2: Characteristics of Prokaryotic and Eukaryotic Cells
Using your pathogen chosen in the Week 1 discussion, describe its cellular characteristics. Describe
which of these structures are used to help it attach/invade/survive in the host. Your response should be
a minimum of 5-6 sentences (100-200 words) and include specific references from Edapt, lecture, or the
textbook.
WEEK 3: Culturing microorganisms
Using your pathogen from the last two weeks, research and describe the ideal growth conditions of your
pathogen. What terms learned this week would describe its ideal growth conditions? What is the
nutritional mode of your microorganism? What are the host cells for your pathogen? Your response
should be a minimum of 5-6 sentences (100-200 words) and include specific references from Edapt,
lecture, or the textbook.
WEEK 4: Controlling Microbial Growth
Using your pathogen from the last three weeks, research and describe the antimicrobials used to
destroy your pathogen, if any. What is the mode of action of that antimicrobial? Is your pathogen
resistant to any antimicrobial?
If no antimicrobials are available for your pathogen, how is the infection treated?
Your response should be a minimum of 5-6 sentences (100-200 words) and include specific references
from Edapt, lecture, or the textbook.
WEEK 5: Adaptive Immunity
Trace the invasion and evasion of the pathogen you chose in Week 1. How does your chosen pathogen
invade/enter the body? Which body system(s) does your pathogen affect? What are the defenses of
that system that the pathogen must overcome (include innate and adaptive defenses)? How does the
pathogen evade/avoid the host’s immune system defenses to survive? Your response should be a
minimum of 6-8 sentences (150-250 words) and include specific references from Edapt, lecture, or the
textbook.
WEEK 6: Epidemiology
Discuss the signs, symptoms, diagnosis, and treatment of your pathogen chosen in week 1. What
signs/symptoms are characteristic of the disease? What are the unique virulence factors of the
pathogen that give this pathophysiological response? Your response should be a minimum of 5-6
sentences (100-200 words) and include specific references from Edapt, lecture, or the textbook.
WEEK 7: Pathogens
We have discussed the cellular characteristics of the pathogen you chose in Week 1 over the last few
weeks. Now you will summarize the most important points to remember about (1) the newspaper
article you chose in week 1, as well as (2) the pathogen’s the cellular characteristics and the disease it
causes. This should be an overall summary of the key features to remember. This should be 6-8
sentences, and around 250-300 words.
After you have completed this summary, use it for your abstract in your Week 6 Pick Your Pathogen
Paper. Use this with the other discussions you have written to complete, correct, and submit your paper
by the end of this week.
