2 Ways How Brooklyn Hipsters Could Be Helpful for Science How many of you reading this article want to end hipsters once and for all? Let's face it, Brooklyn hipsters, in specific, are annoying, can't stop trending, and should not be tolerated with anymore. The only problem is they may actually be beneficial to science. Recent news has surfaced that there is certain bacteria in beards that can actually work as an antibiotic. As people know, many Brooklyn hipsters can be seen with beards, and…

Antibiotics is a great invention in the 1900s. However, they can have some pretty bad side effects and should only be used as a last resort not for a common cold or a flu. *These side effects include, but aren’t limited to: Bad rash Bad sore throat Respiratory difficulties Nausea and vomiting Diarrhea Stomach pain Swelling of joints Stevens-Johnson Syndrome (a rare skin disorder most associated with sulfonamides such as bactrum) Retinal detachment Compromised kidney function (associated with…

INTRODUCTION Being able to identify an unknown specimen in microbiology is vital in the laboratory. The goal of this experiment was to isolate bacteria on a nutrient agar (NA) plate to obtain pure colonies of the unknown specimen. This study was done by applying the methods learned in Professor Sprenkles microbiology lab in determining the unknown bacterial growth present with use of pure culture colony morphology, cell morphology and arrangement, and Gram reaction. MATERIALS AND METHODS The…

In this world, we are experiencing many breakthroughs. There are many men and women who have impacted the world in the field of medicine. One of these individuals is Louis Pasteur, a man who created pasteurization and vaccines. He saved many lives and always found a way to solve problems. Louis Pasteur was a French chemist and microbiologist whose work is renowned all around the world. Louis Pasteur was born on December 27, 1822; in Dole, Jura, France. His father was Jean-Joseph…

Solution CTQ 04: Fundamental Concept:  An agent lethal to bacteria is bactericidal and which inhibits the growth of bacteria is bacteriostatic.  Effectiveness of control agent depends on its concentration, time of exposure and its activity (cidal or static) Solution: • Microbial control agents are of two types based on their effect on microbial cells which are either bactericidal or bacteriostatic. • Bactericidal antibiotics kill (cidal) the bacteria Ex: Polymixin B is a bactericidal agents…

Bacteria employ a few mechanisms to gain antibiotic resistance. One of these – a mutation – involves spontaneous changes within the amino acids of their DNA, which ultimately elicits a modification to a certain gene. The change within the DNA would prevent an antibiotic being used to hinder the bacteria, as it could would no longer recognize the specimen, due to a change in the structure of the target gene. A species of bacteria may also use a method of destruction to chemically degrade or…

Worms. Big worms, small worms, slimy worms. You may not think about worms every day and you might not care for them, but some worms actually play a great role in science. I’m talking about C. elegans. These microscopic worms are being investigated by scientist all the time. They were discovered in the 1970’s by Sydney Brenner and currently an international consortium of laboratories are collaborating on a project to sequence the entire 100,000,000 bases of DNA of the C. elegans genome (CBS). So…

Introduction Antibiotics were initially thought of as a superior drug that could kill many bacterial diseases. Prior to antibiotics, it was hard for anyone to fight a bacteria. However, bacteria are very changing and have begun being able to gain resistance against antibiotics due to overuse, not strong enough dosage of antibiotics, or improper use. By determining the resistance and cross-resistance, one may determine the the relative ability for bacteria to gain resistance to antibiotics. We…

In order for my quality improvement plan to work, the following stakeholders must be part of the plan and fully support the plan. 1. Providers: The doctors must approve the plan and guide their staff in making sure that the correct information is disseminated to the patients. The reasoning is that they are ultimately responsible for this information and have the final say about antibiotic prescriptions. Additionally, doctors are typically the last person that speak to patients from a medical…

“See if you can guess what I am now … I’m a zit. Get it?” - Bluto Background: The purpose of the antiseptic lab was to show the effectiveness of multiple antiseptics: hydrogen Peroxide, Purell hand sanitizer, Water and Iodine. The procedure of the lab for the first day involved our group acquiring a cotton swab and using the swab to gather the Propionibacterium acnes (P. acnes) bacteria from various spots around our face, we then grabbed a Petri dish filled only with a thin layer of agar. We…
