Bacteriophages Essays

When I decided to enroll in becoming a Certified Nursing Assistant (CNA) last 2009, I know that I would be able to deal with different kinds of people and be able to be part of their healing process during their stay in the healthcare institution. Today, as I become a part of the health team, I learned a lot of things. First is being able to know how to communicate and work with different kinds of people may it be our patient or a coworker. In my every day shift at hospitals and nursing homes, I

Germ theory of disease is one of the theories in the biology field. Germ theory of disease supports that microorganisms that are germs are the cause of diseases. This theory was first proposed by Girolamo Fracastoro in the 16th century but he was not able to provide any evidence to strengthen his proposal. This theory was not accepted easily by the citizen between the 16th century to the 18th century. The pre-existence of miasma theory was the obstacle to the acceptance of germ theory during that

involves either a bacteriophage, a virus that infect bacteria or a plasmid, which is a circular piece of DNA that exist and

Arguments against the use of Phages are numerous, but all of them are based around the beginning of phage use. At this time, solutions to these problems have already been found. Issue one is based on the host range of phages. A microbiologist named Michael Schmidt at Medical University of South Carolina described the range of antibiotics and phages as: “Antibiotics are a big hammer...You want a guided missile.” (qtd. in Reardon 15). The solution is to start by screening the infectious bacteria and

actococcus lactis ssp. lactis C2 and bacteriophages c2, ml3, sk1 were obtained from T. R. Klaenhammer (North Carolina State University, Raleigh, NC). Both bacterial Lactococcus lactis ssp. lactis C2 stains and bacteriophages c2, ml3, sk1 were stored in microcentrifuge tubes at -80℃ refrigerator to keep frozen until use. 3.3 Preparation of M17 medium, skim milk, Bottom agar, Top agar and CaCl2 solution M17 medium, skim milk, Bottom agar, Top agar and CaCl2 solution were all prepared in lab 201

PM204 Lab Group: E1 Prepared By: Ahd Mohamed Abdelmoniem Fahmi-175063 Due Date: 20-10-2017   Definition of phage: Phage is a short for bacteriophage, which is virus that lives inside bacteria, and is a piece of nucleic acid RNA or DNA which is bordered by a coat that consists of capsid proteins. The natural host for the virus is bacterial cell. Phages differ in terms of the basic

transformations in which the uptake, integration and expression of extracellular DNA occurs under natural populations of bacteria. Through this mechanism bacteria can acquire DNA from foreign species which are not accessible to mobile genetic elements or bacteriophages. The requirement for this process is that, the bacteria should first develop a physiological state of competence. Some bacterial species, such as Neisseria gonorrhoeae and Haemophilus influenzae, are competent to accept DNA, whereas some others

1) Compare and contrast the terms communicable and infectious disease. There are similarities and differences between communicable disease and infectious disease. Communicable disease is when the disease is transmitted from an affected individual to another individual (person to person). In order to be considering a communicable disease there has to be direct contact between either the individuals or vector. Yellow fever is an example of a communicable disease. Infectious disease is when bacteria

Diversity in individuals is integral in an educational setting in ways that are not always directly visible or perceivable to others around them. These individuals bring experiences, outlooks, talents, and skills that allow for a more enriched and dynamic learning environment and I believe that I can contribute greatly with my own experiences to this shared learning environment. Growing up I was always around animals and because of this my love for animals was fostered on from an early age. Both

According to the World Health Organization, genetic disorders affect one in every twenty-five children born worldwide. We humans, along with all other known organisms, possess genes in our cells that determine everything about how we look and function. Occasionally, an organism may inherit a faulty gene, causing it to have one or several detrimental characteristics known as genetic disorders. This may also occur due to environmental factors that the organism is exposed to, such as ultraviolet radiation

These highly conserved substrates share substantial structural resemblance to the tail tube and needle complex of T4 bacteriophages, respectively, which are required to puncture host membrane in the context of phage infection. Structurally, Hcp and VgrG resemble bacteriophage tail and tailspike proteins, respectively. Hcp and VgrGs form a pilus that is displayed on the bacterial surface. Hcp is secreted by all bacteria with a functional T6SS, and

plaque assay. A plaque assay is a modification of a bacteriophage assay and is used to estimate the titer (concentration of a solution) of a phage stock. A plaque assay contains a virus combined with bacterial cells on the surface of an agar plate. The agar plate inhibits the spread of viral progeny to neighboring bacterial cells which results in plaque formation (lysis of bacterial cell). The purpose of this lab was to perform a bacteriophage assay and to calculate the original stock titer of the

Introduction Double Helix by James Watson discusses many things from the science world, including concepts we have learned this semester. The concepts we have learned this semester that are in the book includes the following: DNA, protein synthesis, cells, viruses, and heredity. Because of the time period this book takes place in, however, Watson does not discuss the concepts in full detail like we can today; but there are connections made between what we discussed this semester and what James Watson

function. Through this they would create more viruses. Most people believe that all of the viruses that enter our body make us ill. Viruses also infect other organisms such as plants and all sorts of animals they can also infect certain bacterias. Bacteriophage is the virus that goes and can

1. Briefly describe how phage were discovered, and how they were quickly used to treat disease. a. Phage were discovered by Felix D'Herelle when he found a motive to search of a "good microbe hunter" after seeing 20 people dead in 8 days due to the yellow fever. He originally discovered phage by chance. While working with sick locusts, he observed a puzzling phenomenon: amid some of his bacterial cultures, there were what he described as "taches vierges" - pure or clear spots on an otherwise cloudy

transformation , and conjugation in microorganisms . Give a definition and main differences with example . - Transduction : it`s a process of transform the genetic material in bacterial cell where the transform of genetic material occur by virus (bacteriophage) , where the virus transfer the genetic material from the host cell to another host cell , where the virus will initiate another cycle of infection . example : prophages , GTA ( gene transfer agent) . - Transformation : it’s the process when bacterial

are certain ingredients in these vaccines that the FDA are not releasing to the public. A common word used in The Dangers of Vaccines in Vaccinations is “unavoidably unsafe”. During the process of making vaccines, there are certain unavoidable bacteriophage that are a big concern. Brain swelling, permanent brain injury, seizures and convulsions, blood disorders, and even death are all significant injuries that are believed to come from

Beginning in September of 2020, as a phage researcher in the SEA-PHAGES program under the supervision of Dr. Susan Gurney and Dr. Brett Condon, I worked with other members of the team to isolate a bacteriophage that had never been discovered. I then utilized bioinformatics to study the virus’ DNA sequence, and this culminated in a poster presentation at the National SEA-PHAGES symposium as well as a publication titled “Isolation and characterization of Microbacterium phages through a virtual lab

For thousands of years humans have influenced the genetics of animals and plants through selective breeding and cultivation of crops. Following the introduction of genetic engineering in 1972, the technology has been utilized in multiple industries - improving the standard of living for human beings throughout the world. Genetically modified tomatoes and strawberries sit in grocery shelves with longer shelf lives. Genetically modified fish glow in a family’s fish tank and genetically engineered bacteria

Introduction The production of identical copies is called cloning, for example in identical twins they are clones where single embryos separate to become two and every single bit of their DNA is identical. So gene cloning means production of many identical copies of the same gene. Gene cloning requires a vector which introduces rDNA into the host cell and enzymes to introduce foreign DNA into vector DNA. Vector is plasmids and enzymes are restriction and ligase enzymes. Of course gene
