fight against them. The more we keep vaccinating against them the more rare they become. Examples include polio and diphtheria. Polio is a virus that can cause paralysis and diphtheria is “ an acute, toxin-mediated disease caused by the bacterium Corynebacterium diphtheria (“Centers of Disease Control: Diphtheria,” n.d.). Even though it may seem that these vaccinations do not work, they do! A great example is the flu. People do not want to receive the flu shot because they think it will cause…

THE ROLE OF ELONGATION FACTORS IN GENE TRANSLATION AND PROTEIN SYNTHESIS. Professor Kinzy’s lab seeks to investigate the structure and function of G- protein in relation to it’s regulation and the post transcriptional processes associated with gene expression. The lab uses Translation Elongation apparatus found in yeast to investigate these processes. The components of these elongation factors are important targets for antibacterial and antifungal drugs such that improper expressions and…

possible with the right staff and training. A culture is considered to likely be contaminated when a single positive culture from multiple sets is positive. Organisms that are considered to be contaminants are coagulase negative staphylococcus, Corynebacterium (except C. jeikium), Bacillus spp., P.acnes, viridian streptococci, and clostridium perfringens. There are many factors that come into play when preventing blood culture contamination. Proper skin preparation, culture bottle preparation,…

Introduction Over the past few years, there is a worldwide increasing tendency for the consumption of functional foods, including probiotics, prebiotics or both. Influenza epidemics cause numerous deaths and millions of hospitalization each year. Because of the alarming emergence of resistance to anti-influenza drugs, there is a need to identify new naturally occurring antiviral molecules. Punicaceae has been used for centuries in many cultures for the prevention and treatment of a wide…

Unknown #11: Introduction: My patient’s name is Cara, she is currently a freshman living in a dormitory with three friends. Just two weeks in, she catches the flu. Her roommates made her soup for the next couple of days from their shared pantry of foods. Cara however progressively becomes worse and now exhibits severe symptoms of nausea and diarrhea. This study was done by applying all of the methods that have been learned so far in the microbiology laboratory class for the identification of…

1. Introduction L-Ornithine is an important chemical ingredient for its applications in food and pharmaceutical industries as a dietary supplement, as it is known to be efficacious in the treatment of liver diseases and wound healing [11]. It can also be used as a precursor for the synthesis of other amino acids, such as arginine and citrulline, and putrescine, an important diamine used as a nylon precursor [28]. L-Ornithine could be produced by fermentation using auxotrophic mutants, for…
