Escherichia coli DH5훂 is the third species being studied. Since E. coli bacteria are considered model organisms, they make perfect study subjects. This particular strain of E. coli is not considered a pathogen. It was made especially for laboratory study. It’s main use has been mostly for cloning.…
My unknown bacteria’s, E.coli, morphology was that the bacteria were rod shaped. E.coli can be found plentifully in nature. E.coli can be found in the gut of endotherms, which are warm-blooded organisms. E.coli can also be found in the normal flora of the human stomach and allows numerous beneficial functions that include the production of vitamin (Nordquist 1). Most strains of E.coli are harmless, however the strain E.coli does have some pathogenic strains that cause…
Thus, these bacteria indicators are easy to identify and safe to work with in the laboratory and their presence provide an evidence of fecal contamination. The fecal category contains both pathogenic and nonpathogenic bacteria. For instance, Escherichia coli or E. coli is a fecal Coliform bacteria. Therefore, the presence of fecal Coliforms is an indicator of fecal contamination and of the potential presence of bacterial pathogens. However, “the intensity of other indicator bacteria (total Coliform, fecal Coliform, and fecal streptococci) is a degree of water safety for body contact recreation or for…
Explanations Animals 1.) Fiddler Crab-I knew that this animal was a fiddler crab because of its habitat. It lived in the mud in my back yard that is part of the intercostal. I also knew it was a fiddler crab because of its huge claw resembling a fiddle, hence its name.…
Some strains of E. coli bacteria (such as a strain called O157:H7) may also cause severe anemia or kidney failure, which can lead to death. Other strains of E. coli can cause urinary tract infections or other infections. The number of E. coli food-poisoning cases linked to Chipotle restaurants in the Northwest continues to rise, with 29 cases in Washington. The count dropped from 12 to 10, in Oregon, however, for a total of 39 confirmed in the outbreak, health officials reported Wednesday. Forty-three restaurants operated by the Mexican fast-food chain remain closed in the two states as regional health officials scramble to identify the genetic fingerprint of specific cases and federal officials designate outbreak-response teams to help.…
Pathogenicity (remember it doesn’t need to be good at everything): Transmission Enters through the ingestion of contaminated water, soil, or plants as a spore. Attachment Uses the TCP acquired from V. Cholerae to attach to intestinal mucosal cells. Invasion Forms a biofilm along the intestinal wall, clearing nearby cilia and producing antibiotics that will kill nearby competing bacteria. Evasion…
Escherichia coli (E. coli) is one of the most widely studied and understood living organisms. It has been used for decades in furthering understanding of gene functionality and gene-protein mechanisms for prokaryotes and eukaryotes alike (Riley et al. 2006). Prokaryotes, like E. coli, have their DNA in the form of a plasmid. A plasmid is a circular ring of DNA. The plasmid intended to transform the E. coli colonies for the purposes of this study was the pGLO plasmid.…
A prokaryote is a single-celled organism that does not have a nucleus and membrane-bound organelles. In the prokaryotes, the proteins, DNA and metabolites are all located together in the cytoplasm enclosed by the cell membrane. Bacteria, however, contain bacterial micro compartments, which are thought to act as primitive organelles enclosed in protein…
There are so many different diseases and sicknesses known to man that involve bacteria and other circumstances. A few of these being Crohn's Disease, Food Poisoning, Meningitis, and Ulcers. These bacteria are deadly in some cases and cause many problems in your body. The first thing we will do is go into what bacteria is and where it would be found. There are millions and billions of bacteria that exist that we cannot see.…
E-Coli is a type of bacteria. There are many types of E-Coli, and most of them are harmless. But some could be very dangerous to humans that could lead up to death. This bacteria is mostly found in human and animal intestines.…
These new forms of bacteria colony growth have unknown potential when it comes to human health. The effects of zero gravity can reduce the danger of some bacteria or visa verse. To understand the effects of bacteria such as E. coli in space would allow us to better foresee the dangerous situations that could occur on longer missions further away from Earth (Dunbar,…
It is present in the nose of about 30% of healthy adults and on the skin of about 20%. The percentages are higher for people who are patients in a hospital or who work there. The bacteria can be transmitted from the nose and the skin through individuals’ hands and can contaminate surface areas. Escherichia coli is a gram negative, facultative anaerobic bacteria. Its harmful symptoms include severe stomach cramps, diarrhea (often watery and may develop into bloody), vomiting, and fevers.…
Conclusion: The experiment has showed how some bacteria have become extremely versatile and able to live in many environments and how other have not changed much over the course of time. It has showed how use of sugar, growth based on enzymes, and ability to ferment as well as motility can help us identify multiple bacteria and distinguish them from each other. This will be useful to come in the Isolating and Identifying Bacteria project since we have already isolated and observed the bacteria the information learned in this lab gives us ways to test and observe our bacterial cultures so we can compare results back to our data and attempt to properly identify them. Real world implications of this lab show how difficult it is to obtain growth in a lab at times and how tedious it can be, but also provides a database of sorts to look back upon to help study bacteria and identify which ones cause illness, where they can be found, how to test for them to prevent illness and contamination and possible ways to fight them knowing what they need to survive and what defenses and attributes they…
Units of the Archaea can be described as inhabitants of drastically hostile surrondings. The Eubacteria, are pervasive living agreeably in most enviornments. Every breath carries some bacterial spores, and almost every surface holds them. When it comes to the intestines, some are helpful, giving nutrients, vitamins and absorbing water in return for space. Some prokaryotes are our enemies, causing diseases and…
Bacteria are one-celled organisms. When looked at under a microscope, they appear to be balls, rods, or spirals. Contrary to popular belief, most bacteria are actually good for other organisms. Under 1% of bacteria on Earth cause disease, and the bacteria that do can usually be treated with antibiotics (“Bacterial Infections: Medline Plus,” par 1).…
