Taking a Look at Escherichia Coli - 805 Words

Escherichia coli is a gram-negative bacillus that is facultatively anaerobic and which is classified as part of the Enterobacteriaceae family. It is most commonly found in the lower intestines of warm blooded organisms although it is capable of surviving outside of the host for an extended time and may be spread through contact of infected fecal matter as well as personal contact with an infected host. Several strains of E. coli live in endotherms as part of the normal flora of the gut and provide their hosts with benefits such as the production of vitamin K2 and the prevention of establishment of the intestines by pathogenic bacteria thereby forming a mutualistic relationship with their hosts. There are five strains of E. coli which can cause gastroenteritis in people through the production of shiga toxins leading to illness and even death. However E. coli has been a large part of many valuable contributions to science for the last 60 years due to its genetic simplicity as well as i ts fast growth and inexpensive culturing requirements. Escherichia coli is a well studied prokaryote and may be considered a foundation of biotechnology with the work of Herbert Boyer and Stanley Norman Cohen who used E. coli plasmids in conjunction with restriction enzymes and produced recombinant DNA.1 Even before the application of the rDNA technology, the first industrial application of E. coli being the production of the amino acid threonine in 1961 by the induced mutagenesis of theShow MoreRelatedAntimicrobial Lab Report1105 Words   |  5 Pagesthe edge of the zone of inhibition. The MIC is determined by comparing the zone of inhibition with the *Table 1 MIC values. The cultures assigned were Staphylococcus aureus (gram positive bacteria), and Escherichia coli (gram negative bacteria). However, results that are shown are from Escherichia coli. The antibiotics used were Bacitracin, Penicillin, Streptomycin, and Tetracycline. The antibacterial reaction as a whole relies upon the relationship between the cell wall and the antibioticRead MoreThe Effects of Environmental Factors on the Absorbance of Escherichia Coli1674 Words   |  7 Pagesbacterium Escherichia coli is being subjected to various environmental factors that affect the rate of growth. These factors scrutinized were the different types of nutrients, the intensity of aeration, or the temperature at which it was stored. The purpose of this lab is to determine which factor affects the Escherichia coli the greatest. It is known that these abiotic factors affect the rate of growth the greatest if they remain at the correct conditions for living. Escherichia coli and otherRead MoreE.

This is the most recent condition on E. coli outbreaks in North Carolina. In 2004, E. coli O157:H7 infection was responsible for making 108 visitors toRead MoreHow A Bacterial Can Make Any Type Of Meat Go Bad912 Words   |  4 Pagestemperatures. A couple to name incorporate E coli, salmonella and Staphylococcus nourishment harming. Escherichia coli (E. coli) is exchanged through the defecation of some kind of species. For instance if a fly grounds on the meat forgot and exchanges defecation to the meat then the microorganisms enters the meat. Regardless of th e fact that the meat is cooked to appropriate temperature, the microscopic organisms can survive and still impact the shopper.

The reason why is was so important taking a more organized approach rather than just doing test after test because it would have taken way too long just doing test after test and then gathering all you data at the end to determine what organism you have. It is so much easier and far lessRead MoreCreating an E. Coli Strain to Produce Antivenom Essay example3358 Words   |  14 PagesLipps 2003, Lipps 2008 B). Our solution is to create a universal antivenom is modify a strain of Escherichia coli to produce LT-15 (Lipps Lipps 2005). We will insert the LT-15 gene into a plasmid with a promoter, then transform E. coli with the plasmid and grow the recombinant strain. (Cawood 2013, Cohen et al. 1973, Huang et al. 2012, Lipps 2002 B, Lodish et al. 2000, Muyrersa et al. 2001). These E. coli can then be grown and harvested industrially for LT-15. This is a novel project because thisRead MoreUrinary Tract Infection And Its Effect On The Body System1245 Words   |  5 Pagesa patient who is on a catheter can also get a urinary tract infection. The two types of urinary tract infections are infection of the bladder (Cystitis) and infection of the urethra (urethritis). Cystitis is a type of UTI which is caused by Escherichia coli, a type of bacteria that is normally found in the gastrointestinal tract (www.webmd.com).

Although there are large groups of E.coli, most strains are harmless. Other strains of the bacteria may cause diarrhea, respiratory illnesses and food poisoning. Some strains such as O157:H7 can cause kidney failure or severe anemia. Exposure to
