Escherichia Coli is a rod-shaped bacterium that measures approximately 0.5 μm in width by 2 μm in length. It is a Gram-negative bacterium. Its cells stain gram negative because they have a thin cell wall with only one to two layers of peptidoglycan. They live in environments with higher temperatures rather than cooler temperatures. E. coli is said to be the “model organism”. Many microbiologists use these bacteria as a resource for understanding other prokaryotic life and are the most carefully
pus from surgical abscesses. (Mandal, 2012). Escherichia coli, belongs to the family of Enterobacteriaceae. It is a gram-negative bacteria, with a rod shaped and a non spore forming motile with peritrichous flagella. This bacteria form a colony of two to three (2-3mm) in diameter that grow in MacConkey agar.
Escherichia albertii is an emerging gram-negative discretional rod that has been related to multiple cases of human diarrheal disease, especially in young children. The purposes of this study were to illustrate the antibiotic resistance traits and the growth of individual strains of E. albertii on raw ground beef at different storage temperatures. First, the bacteria stains were isolated. Next, using the Broth microdilution assay (a method used to test the susceptibility of bacteria to antibiotics)
were expected to be able to meet five outcomes: Demonstrate Knowledge, Conduct Group and Individual Research, Address Environmental Problems, Make Ethical Decisions In Care for Others, and Communicate in a Scholarly fashion. The purpose of this final assignment is to briefly describe how I met the student learning outcomes for the course. Demonstrate Knowledge / Conduct Group and Individual Research During the course, we completed two group projects and four individual assessments. Within Leadership
founders of Crest toothpaste had to come up with a plan to reduce the number of Americans with tooth decay. So they began to research beneficial ingredients to add to their toothpaste. In the 1940s, Americans were estimated to have over 700 million cavities a year, making dental disease one of the most prevalent of U.S. health problems (Procter &
Efficacy of Tea Tree oil (Melaleuca alternifolia), Honey, and Capsicum annuum Against Staphylococcus epidermidis and Escherichia coli Kenzie Perryman, Daniela Perez, and Alexa West Department of Life, Earth and Environmental Sciences, College of Agriculture, Science and Engineering, West Texas A&M University, Canyon, TX 79016 November 8, 2015 This experiment was designed to examine the efficacy of naturally occurring antimicrobials against common bacteria located in a normal human microbiome
THE EFFECT OF INCREASING THE CONCENTRATION OF DETTOL ANTISEPTIC LIQUID ON THE GROWTH OF E.COLI Background: Escherichia coli are rod shaped, gram negative bacteria often found in the gut of humans and other warm-blooded mammals (Jacques & Ngo, 2004). It is transmitted primarily through faecal contaminated food and water. Most strains of E. coli are not harmful to humans, however some strains are pathogenic and can cause symptoms including diarrhoea (Unknown, 2012). The active ingredient in Dettol
The bacteria used for the experiment was Escherichia coli and the genes introduces for the transformation were: gfp and bla by a pGLO™ plasmid. After the insertion of the target genes and growing the bacteria on specialized LB media, it could be seen that the transformants were positive for the gene expression. The transformed E. coli on the media appeared fluorescent green under UV light. Introduction The bacteria used in this experiment is Escherichia coli which is not naturally competent.
Science and Engineering University of Wolverhampton United Kingdom Abstract This paper critically reviewed an existing literature on impact of municipal solid waste on groundwater quality in order to identify the extent of physio-chemical and biological parameters compared to World Health standard guideline for drinking water quality. To address the aim more than ten (10) academic articles were reviewed. An existing research showed that, in most of the developing countries, municipal solid waste is generated
aid in the fight against various bacteria. The use of plants as well as silver nanoparticles to fight against bacteria has caused much interest in the nanotechnology and medicine fields, and has been the basis of many studies. The purpose of this paper is to scrutinize the antimicrobial potency of silver nanoparticles, and how they may be utilized to fight against various harmful bacteria. Bacteria: The Antimicrobial Potency of Biosynthesized Silver Nanoparticles against It Bacteria are
