Fall 2023: Week 7

Hi Everyone, This week, I focused on my experiment's optical density part. Unfortunately, when I came in on Monday, I discovered the liquid had evaporated sometime over the weekend. I had to make a new sample, increasing the amount of media in each. On Thursday, I took the optical density of the new sample. It showed that all three types of honey inhibited growth. Manuka Honey 1 had the most potent MGO concentration and had the least growth. MGO, or methylglyoxal, is the compound accredited for honey's antimicrobial properties. The new sample showed evidence of cross contamination in the control well (media), so I'm testing the media to see if the whole bottle is contaminated. The next step is determining the minimum inhibitory concentration with a two-fold dilution.

Week 9: Interesting results

On Tuesday, I plated E. Coli and tested the effectiveness of 4 samples to kill the bacteria. The sample included , Aloe Vera gel (store bought), Windex, Tap water, and 70% Isopropyl Alcohol. This experiment was pretty much used to keep me busy as I haven't yet been able to start a project. However when I came in Wednesday, I found some interesting results. The zone of inhibition was basically 0 for every sample, including the isopropyl alcohol. Although the tap water, being the control, and the Windex doesn't jump out as a surprise to me, the 70% Alcohol does. Originally I had two hypothesis's on why this occurred. One being that because E. Coli is a gut bacteria and therefore is built to withstand alcohol. The second theory suggest user error such as the letting the alcohol evaporate to much before I was able to put the disk on the plate. Because of the results on Wednesday and with the first hypothesis in mind, I chose to do another plate instead with Staphylococcus. I ch...

Spring 2024-Week 7

Pseudomonas aeruginosa is a pathogen found in dirt. It has become more commonly associated with hospital-related infections, including those such as ventilator-associated pneumonia. (Lima et al., 2017) It is also known for being particularly hard to kill because of its high intrinsic antibiotic resistance. Staphylococcus epidermidis and Staphylococcus aureus are considered two of the most prevalent pathogens in hospital-related infections. These strains of Staphylococcus usually are part of the human microbiota, and they can contaminate medical instruments and implants and cause infections. (Chessa et al., 2016) Certain strains of Staphylococcus Aureus have gained the ability to resist the antibiotic methicillin. This strain is known as methicillin-resistant Staphylococcus Aureus (MRSA). (Kot et al., 2020) Due to the increased emergence of antibiotic-resistant bacteria, finding new ways to combat these pathogens has become essential. Their ability to form biofilms makes each of these b...

Fall 2023: Week 2

Hi Everyone, It's great to be back with TRAIN this semester. Lately I've been researching and reading articles related to my project. Since I"ve decided to ditch last semester project, and come up with my own there's been a lot of brainstorming. I'm excited to put together something from scratch. I already have something in mind and now it's up to me and Josh to conduct this project within limitations. Either way I can't wait.
