PraShawn Hampton Period:1 Barbracide in the Salon Back in 1947 in New York‚ Maurice King prepared a chemical product that would help take sanitation to another level. Barbracide is a big reason why most salons and barbershops are still open today. Barbicide helps remove all of the bacteria and germs off of barbershop and salon implements such as: razors‚ combs‚ hair clips‚ and sanitizes stations. The iconic blue liquid is well known for being a disinfectant‚ but as well as that‚ the use of barbicide

In the first experiment‚ the bacteria R. fascians and R. corynebacterioides grew equally well in all conditions of light‚ except ultraviolet light. We tested this by comparing the petri dishes to the petri dishes that grew without light. Here‚ the exposure time was constant for all the lights and no light‚ which is 48 hours. The light sources were different. However‚ none of the lights had an effect on the bacteria‚ for the bacteria just continued to grow normally. The only exception was that UV

In the field of science‚ new discoveries are being made every day. Even though scientists are finding new things every day‚ over 99% of bacteria or antibiotics aren’t discovered. However‚ recently a new antibiotic called teixobactin was discovered. This antibiotic prevents the synthesis of a cell wall by binding to a motif of lipid II and lipid III molecules. The goal of this experiment was to discover how teixobactin interact with bacteria and how it is able to effectively kill pathogens. A device

I was able to come to the conclusion that my unknown is Klebsiella pneumoniae through the use of Bergey’s Manual. After performing a gram stain of my unknown I was able to determine that my unknown was a gram-negative rod. While testing the oxygen requirements my test tube had growth throughout the tube‚ indicating my unknown was a facultative anaerobe‚ which can grow in the presence or absence of oxygen. The most important test was whether my unknown was motile or nonmotile. My test tube only showed

Personal Statement My decision to pursue my graduate studies in the United States stems from my desire to build up a successful career in research in biomedical sciences. Earning a Ph.D. in Pharmaceutical Sciences with a concentration in Pharmacology and Toxicology from the University of Oklahoma will definitely be a crucial step in fulfilling my dream. I am currently pursuing Master of Science in Chemistry at Lamar University‚ Beaumont‚ Texas. I earned my undergraduate degree in pharmacy from Jahangirnagar

What is campylobacter? It is an infectious disease caused by bacteria of the genus Campylobacter. When you become ill with Campylobacter you will have symptom such as fever‚ abdominal pain‚ cramping‚ and diarrhea within two to five days after your exposure. The Campylobacter jejuni infection outbreak uncovering in Pennsylvania thought the sale of unpasteurized dairy product; this article had discussed that as a result of the unpasteurized milk that 148 cases of Campylobacter jejuni infection had

Molecular Characterization of Methicillin-Resistant Staphylococcus aureus (MRSA) Nasal Colonization and Infection Isolates in a Veterans Affairs Hospital Staphylococcus aureus (S. aureus) belongs to the genus Staphylococcus. It is Gram-positive‚ cocci shaped anaerobic bacteria that forms clusters and produces catalase‚ which catalyzes hydrogen peroxide to water and oxygen. It contains a cell wall structure (including peptidoglycan and teichoic acid) and a low G + C content of DNA between 30-40 mol

Recombinant DNA Technology How to Mess with DNA for Fun and Profit OR OR How to Make a Mouse Glow in the Dark What the heck is Recombinant DNA? Recombinant DNA is what you get when you combine DNA from two different sources. For example: Mouse + Human DNA Human + Bacterial DNA Viral + Bacterial DNA Human + (other) Human DNA (It’s sort of like Frankenstein-DNA!) Why Make Recombinant DNA? Recombinant DNA Technology May Allow Us To: • Cure or treat disease • Genetically modify
Premium DNA Molecular biology Escherichia coli
Introduction: Bacteria are microscopic‚ single-celled organisms. Their genetic information is encoded in one large chromosome. It can also be found in plasmids which are small circular pieces of DNA that contain important genetic information for the growth of bacteria. In nature‚ this information is often a gene that encodes a protein that will make the bacteria resistant to an antibiotic. The reason for this protein being made within the bacteria is because of how bacteria usually grow in the same

K. pneumoniae is a gram negative‚ facultative anaerobic‚ gamma-proteobacteria that can cause pneumonia‚ urinary tract infections‚ cholecystitis‚ and septicemia. (Strand & Shulman 1988) As shown in Table 1.‚ many organisms have developed resistances to commonly used antibiotics. The difference between the standard strain of Klebsiella pneumoniae and the extended spectrum betalactemase (ESBL) strain‚ for example‚ is striking. 12 antibiotics had greater than or equal to 95 percent effectiveness against
