WEEK 1Explain the importance of microbiology and how it relates to the nursing profession (USLO 1.1)List the major groups of microorganisms and provide an example of each (USLO 1.2)Choose one historical advancement in microbiology (USLO 1.3)Describe methods used in microbiology such as microscopy and staining techniques (USLO 1.4)
WEEK 2Prompt 1:Name the organism to which you were assigned for the Microorganism Profile Assignment and list: Mycoplasma Pneumonia
Prompt 2: Please select 2 of the prompts below to discuss:Compare prokaryotic and eukaryotic cells. Be sure to include at least 2 similarities and 2 differences.
Prokaryotic cells: One circular chromosomeComplex cell walls70s ribosomesUnicellularVery smallRelatively simpleEukaryotic cells:Has a nucleusMultiple linear chromosomesMembrane bound organellesSimple cell wallsSterols in cell membrane80s ribosomesUnicellular or multicellularLarger More complex than prokaryoticStructures they have in common:DNARibosomesCytoplasmMay have flagellaMay be pathogenicIt is important to note that because prokaryotic does not have a nucleus it is unable to go through the process of mitosis (nuclear division). Prokaryotic cells go through the process of binary fission as the DNA replicates the cell gets larger and eventually splits in half. Therefore, prokaryotic cells can multiply quickly as quickly as every 20minutes. E choli is a prokaryotic cell so one cell in twenty minutes can double and that number can double 20minutes later. We can see how infections can get so out of control so quickly, especially with a weaken immune system.Discuss the differences between gram positive and gram-negative cell walls. Why is this important information to understand? (USLO 1.3)
