Coli

E.coli outbreaks have steadily grown over the last few decades. An expansion in big farming has led to E. coli not only being found in meat, but vegetation as well, due to waste runoff. This has increased our need for adequate antibiotics that can fight bacteria, like E. coli. The best way to pinpoint which antibiotics work is by measuring their ability to create antimicrobial agents or zones of inhibition. When a paper disc that has been saturated in an antibiotic is inserted in a solution of E

TRANSFORMATION AND SURVIVAL OF E. COLI Introduction: With changes in technology over the past decades, came new knowledge of the biology realm. With this new knowledge and understanding of biology came about Biotechnology. Biotechnology is the process of harnessing the ability of living systems to quickly and inexpensively produce important biological materials. We can see the results of Biotechnology in all areas of our life including the food we eat and the medicine we take. Today, we are using

Erick Espino Dr. White Bio 1B section 15 29 April 2016 MIC Effectiveness of Tetracycline on E. coli Abstract Tetracycline is a common antibiotic that is used to treat many patients that have infections such as urinary and respiratory infections. The objective of this research was to analyze the effects of Tetracycline on E.coli, in order to determine if it would have a dose response to the sensitive strain DH5Alpha. For the experiment, we had to prepare a bacterial Serial Dilution based on our

Transformation of the pAMP to the E. coli showed growth in all plates that did not contain ampicillin, which was to be expected as E. coli with or without the ampicillin resistant DNA would be expected to survive in an environment that did not contain the ampicillin. Additionally, E. coli that was not transformed did not survive in plates containing ampicillin; a fact that we had already predicted as the bacteria has no genes protecting it from the deadly antibiotic. However, we found slightly different

resistance in Escherichia coli (E. coli) and which disinfectant has the greatest effect on the bacteria? 1.2 Context Other research concerning antibiotics/resistance/disinfectants 1.3 Significance The results of this investigation has a large degree of significance to the real world. Many people use disinfectants, such as the ones used in this investigation, to clean their outside environments (the outside world) and their inside environment (their body) from the E. Coli disease. Investigating and

Introduction Escherichia coli are bacteria commonly found in the intestines of humans and other animals (Water: Basic Information about Regulated Drinking Water Contaminants 2009). Many strains of E.coli are harmless and contribute to healthy intestinal tracts. However, some strains can cause illness, including abdominal cramps, diarrhea, vomiting, hemorrhagic colitis, and hemolytic uremic syndrome (Tian Ding 2012). Most infections caused by pathogenic strains of E. coli are caused by ingestion of

Introduction The purpose of this lab experiment was to measure the population growth of Escherichia coli, or E. coli, a type of bacteria that can be found in the human body, specifically in the large intestine. It works to aid in digestion as well as the absorption of essential nutrients. While E. coli is extremely beneficial to the human body and most populations are safe for humans, some cause disease if they end up in food that is eaten (Trzepacz et al.) Sickness can occur when waste reaches

1. Introduction The gram-negative bacilli were first discovered and described by Theodor Escherich, a German pediatrician in 1885. Originally named as Bacterium coli commune, the name was changed to Escherichia coli (E.coli) (Stanford T. Shulman et al., 2007). E.coli is known as the most free-living organism being studied. More than 700 E.coli serotypes have been discovered. Their “O” antigen (somatic), and “H” antigen (flagellar) and “K” antigen (capsular) distinguish the different E.coli serotypes

The experiment was a success and the four E Coli plates brought forth the expected results. The two control plates were -pGLo LB and -pGLo LB/amp. On the -pGLo LB plate, there was no ampicillin to prevent the growth of E Coli so the bacteria thrived and grew massively across the plate. There were no specific colonies, rather there was E Coli spread out across the entirety of the gel. This serves as a control because it proves that E Coli was able to grow in the environment provided for it. On the

” E. coli is one of the most frequent causes of many common bacterial infections, including cholecystitis bacteremia, cholangitis, urinary tract infection (UTI), and traveler's diarrhea, and other clinical infections such as neonatal meningitis and pneumonia.” Says the food poison journal, All You Need To Know About E. coli. The bacteria was first called bacterium coli but then was changed to Escherichia coli to honor the scientist that discovered it. There are over 700 serotypes of E. coli that
