Emma Bythewood Section 12 BIOL 2260L Extra Credit Option One 1. What aspect(s) of this laboratory course can/will you take over into your nursing career ? There are many aspects I learned from this laboratory course that I will be taking into my nursing career in the future. One of those aspects is the aseptic technique because is it the most basic technique when dealing with microorganisms, especially in a hospital setting. It is extremely important to practice this technique to avoid the spread of infection and cross-contamination while testing in a laboratory setting. Another aspect I will take into my career is the microscope technique. I foresee using a microscope will be a common occurrence in my future career as I will be handling testing and identification of disease and infection. All techniques for testing will follow me into my career, but the knowledge of the use of a microscope is a fundamental technique for being able to adequately do my job. 2. Identify a microbe that you may encounter in your career (or one you just think is interesting), and various characteristics about it. One microbe that I might encounter frequently in my career is Escherichia coli . It is one of the most common microbes that cause neonatal sepsis in premature infants. Since their immune system is less developed than an infant born maturely, they are more susceptible to this bacteria. The most common way it is transmitted is from mother to baby during delivery, surprisingly. E. coli is very interesting to me due to many things, one of which is that most types of E. coli are harmless, and some are even helpful. This bacteria is so diverse and can even cause pneumonia, which is not typical of bacilli found in the gastrointestinal tract. It is a Gram-Positive bacteria, so I will stain

purple, and it grows on EMB and Mac Conkey agar. E. coli is susceptible to ciprofloxacin and norfloxacin. I believe this will be one of the most common microbes that I will be seeing in my career. 3. Write an overview about a lab unit of your choice, compete with key takeaways . The lab units that made the largest impact to me were units 5 and 6: Diagnostic Microbiology of Gram-Positive and Gram-Negative bacteria. Gram testing is the very first step in identifying a microbe. Finding out if a microbe is positive or negative sets up a line of more in- depth testing to being able to correctly classify a specific microbe. In these labs, we followed a flow chart of tests for identification and did testing depending on the result of the previous test. Each test clearly differentiated between Gram-Positive and Gram-Negative bacteria, and from there we were able to differentiate Streptococci from Staphylococci with the Catalase test. These tests are crucial to identifying key characteristics of bacteria so proper treatment can be administered.
