Escherichia Coli Investigation

bacterial 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

Abstract: The objective of the investigation was to perform multiple experiments that would lead to the identification of an unknown bacteria. This bacteria was causing a urinary tract infection on a patient. A sample of the bacteria causing the infection was received and analyzed. The first step was to isolate the bacteria to insure that sample was free of contamination. A MAC plate, a PEA plate, along with a Nutrient agar plate where used to produce pure colonies by using the quadrant streak

as human insulin and drought resistant crops. In this experiment, the attention was focused on the bacteria, Escherichia coli, also known as E. coli, that is commonly found in intestinal stools. This experiment was conducted in order to test the hypothesis that the GFP will glow underneath the UV light if +pGLO +Ara (Arabinose sugar) were present. It is an overall interesting investigation because bacterial transformation has benefits in agriculture, bioremediation, and even in medicine today that

Grill faced a serious problem with food safety and received an ethical backlash because of it. According to the Food and Drug Administration (FDA), the Centers for Disease Control (CDC) along with state and local officials investigated two cases of E. coli O26 infection outbreaks from food served by Chipotle restaurants in several states

Introduction The development and dissemination of bacterial resistance to 3rd generation cephalosporin antimicrobials is of significant importance to public health and domestic livestock production alike. The World Health Organization recognizes the extended-spectrum cephalosporin antimicrobials as “critically important” and their use in food animal production is coming under increasing scrutiny (1). Reports of recovery of blaCMY-2 and blaCTX-M resistance genes in bacterial isolates from U.S. livestock

for bacterial transformation. The plasmids can be altered to include donor DNA thus altering the physiological or physical characteristics of the bacterium. Escherichia coli have been found to be the most effective bacterium in genetic transformation and heterologous expression of human genes or proteins. It was hypothesised that Escherichia coli HB101 K12 could be transformed with a pGLO plasmid to express the genes encoded for green fluorescent protein (GFP), the bla gene for ampicillin resistance

Research Question: To investigate the antimicrobial substances, bleach and lemon and their effectiveness in eliminating the zone of inhibition of Escherichia coli (E-coli). Background Information: An infection usually matures within 3 to 4 days of the consummation of food that is contaminated and symptoms usually include severe bloody diarrhoea and abdominal cramps, however in some cases, the infection causes no symptoms. Practical measures to control the spread of the bacteria include practicing

antimicrobial use practices for the sampled group of animals beginning in the farrowing phase. Fecal samples were shipped overnight to The Ohio State University for bacterial culture of E. coli and Salmonella, and selective enrichment with media containing cephalosporins: E.coli: For blaCMY-2 selective E. coli culture, a 4 gram aliquot of

WHAT IS THE EFFICIENCY OF THE ANITBACTERIAL PROPERTIES OF SOME NAMED HANDWASHE DETERGENTS ON ESCHERIA COLI AND STAHPILOCOCCUS AUREUS? Aim: To investigate the efficiency of the antibacterial properties of some named hand-washes on Escherichia coli (E. coli) and staphylococcus aureus and in the process comparing the two bacteria species. The mutagen o be used will be dilute detergent paste. Introduction Bacteria constitute a large domain of the prokaryotic microorganisms. They come in different sizes
