Spring 2024-Week 8

Hi Everyone, Hope everyone had a nice spring break. I spent most of the break taking long naps and enjoying my birthday. I never realize how tired school and constantly being on the go makes me feel until it all comes to a stop. This week is about finding my groove again, but I also have to worry about the second exams for my science classes. When I returned from break, none of the bacteria turned black (or any color) on the conga red plates. Black would've indicated biofilm-forming bacteria. Josh and I are sure the pseudomonas aeruginosa is at least a biofilm-forming bacteria, which leads us to believe that something is wrong with the conga red in the agar plates. To prove our theory (pseudomonas aeruginosa being a biofilm-forming bacteria), we've put pieces of foil in TSB to promote biofilm growth. We are doing this because we noted that for biofilm to form, it needed a surface to adhere to.

Fall 2024- Week 5

Hi Everyone, This week was my first whole week in the lab. I focused mainly on calculations and locating everything I needed for the next few weeks. I also made fresh media this week. We made a few adjustments to last year's protocol in hopes that we get better jobs. We made adjustments by ordering flat bottom well plates to help bacterial biofilms stick better. We got an adhesive film to cover the plates to avoid too much evaporation and cross-contamination. By next week, I plan to plate some bacteria and measure the biofilms. (I had to autoclave my media and bottles to store it in)

Fall 2024-Week 13

Hi everyone, I hope everyone had an ejoyable thanksgiving.There isn't much for me to say. I was able to finish my experiments before leaving for vacation last week. I plan on analyzing my results and finishing my research paper. I also plan to work on the final presentation. This week was also my last week for the organic chemistry lab and lecture. I'll be taking the organic chemistry final on monday so wish me luck.

Fall-2024 Week 7

Staphylococcus aureus is considered one of the most prevalent pathogens in hospital-related infections. This strain of Staphylococcus are apart 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 bacteria difficult. Biofilm formation is one of the leading contributors to antibiotic resistance and hospital-related infections. The biofilm allows bacteria to stick and multiply on medical instruments. Biofilms comprise extracellular polymeric substance (EPS), S. Epidermis, and S. Aureus biofilms, which are polysaccharides, amyloids, and pro...
