...E Coli is one of the three most deadly diseases in the world. It has a very high mortality and with thousands infected every year. It has had many major outbreaks since 1993. Due to how deadly it is, it is a huge topic to study by many biologists. E Coli has many different symptoms, causes, and preventions. E Coli has a large variety of symptoms. Some of the common symptoms out there include severe stomach cramps, diarrhea, and vomiting. The infected person may also have a mild fever. Around 10 % of infected victims develop hemolytic uremic syndrome which can be extremely fatal. This causes seizures, strokes, and kidney dialysis. There are also potential long-term effects of permanent kidney damage. Symptoms usually start after 3 to 4 days...

...Escherichia Coli (E. Coli) are found in nearly all parts of the environment, foods, and even inside in all organisms. Majority of this bacteria is harmless, but it could also be potentially beneficial and even disadvantageous. Research has proven that some types of E. Coli can be the source of illness such as diarreach urinary tract infections, and many other varieties of illnesses. It is possible you many be exposed to this bacteria from the contamination found in our daily food and water (It is commonly present in raw and uncooked vegetables and meats.) Although the recovery process is can be easily facilitated, it is crucial prevent this illness as it may put you at risk for developing a life-threatening diseases linked to this bacteria. (MedicineNet, 2017). E. Coli cannot be seen, tasted, or even smaller, however, it can be deadly. Previously mentioned, E. Coli is commonly found in meat, unpasteurized milk, raw vegetables, contaminated beverages. Many of these examples have been recalled because of the contamination E. Coli caused. Some foodborne illnesses linked to this bacteria salmonella and cryptosporidium. The bacteria is most often spread person to person through hand or mouth contact (Who, 2018). However, there are certainly practices that are followed to treat...

...E.coli is a bacteria that is often associated with cows. Recent studies have shown that outbreaks of E.coli are the result of diets in cows containing corn and starches. (www.ansc.purdue.edu). In the past couple of years cattle diets have been changed to be more cost effective and now contain mostly corn and corn-byproducts. This change in diet has led to many severe effects in the health of the animals including in increase of E.coli. This E.coli strain is the third most deadly bacterial toxin, coming in behind the pathogens that cause tetanus and botulism. So when not handled properly handled E.coli can cause serious health problems or even death in the people that eat beef and other meats. E. coli contamination is responsible for more than...

...bacteria, parasites or viruses. These infections affect the testicles, the epididymis (a reservoir where the sperm is collected after it leaves the testicles), and the production of male sex hormones. If a woman has a partner that has been diagnosed with a low sperm count, this might have originated from a urinary tract infection or a previous infection of venereal disease. Sperm themselves can also be affected since micro-organisms can affect their development, maturation and motility (how they swim). Another common type of urinary infection is from Escherichia Coli (E-coli). The e-coli bug grows in the intestines of humans and is usually good for you. They are part of the immune system as well as being responsible for the production of a type of vitamin K, which helps with the coagulation of blood; the e-coli bacteria prevent pathogenic infections by eating the bad bacteria in the gut. In many cases, too many e-coli multiply and they can spill out of the intestinal tract and end up clinging to the urethra (the tube which carries urine from the bladder to the outside of the body) and infect...

...The question of identity is complex, to be certain. Philosophical thinkers have been wrestling with the question for centuries. Such intellectual exercises have frequently been rooted in the idea that no matter the individual differences between us, we are the “same” because each of us is, at base, a human being. Using this as the basis for understanding our individual identities within the context of a civilized, democratic society, we should be able to co-exist harmoniously in a country founded on the following familiar words from the United States Declaration of Independence, “We hold these truths to be self-evident, that all men are created equal, that they are endowed by their Creator with certain inalienable rights, that among these are life, liberty and the pursuit of happiness.” The reality of the situation, however, is arguably that white culture has interpreted these words to mean that anyone who identifies themselves as not white, either by some physical trait, or a set of ideologies that do not mirror the protestant values on which this country was founded, is essentially and innately substandard. As a result, they are marginalized and assigned a sub-par position within society. Certain groups are notable for the social and political resistance they begin to demonstrate against the white establishment. Two notable groups which have shown (and continue to show) such resistance are African-Americans and the LGBT community, significantly notable because both groups...

...Plasmids are small pieces of double stranded circular DNA found in the nucleoid region of mostly prokaryotic organisms such as bacteria. Plasmids benefit their host by serving as vectors and providing them with genes that benefit its survival. Some examples of genes carried by plasmids include antibiotic resistance, special enzymes, and toxic encoding. In bacteria, chromosomes serve as carriers for information that is essential for its survival, plasmids on the other hand, only supply additional information that though beneficial is not needed. The simple role that they serve allows them to be small in size, replicate more easily, and suffer less damage when being handled. This allows plasmids to transfer from one bacterium to another by three processes: transformation, transduction, and conjugation. In conjugation, one bacterium transfers a gene to another by direct contact, this is mostly seen in nature between neighboring bacteria. Transduction on the other hand occurs when a gene is transferred in the form of a virus infecting and reproducing inside a new organism. The most common form used by scientist is transformation. Transformation is the process by which bacterial cells take up DNA molecules from a donor cell using a plasmid or virus as a vector. In order for transformation to take place, there must be a host into which DNA can be inserted, a vector to deliver the DNA and a way of identifying the transformed cells. In the experiment conducted, E.coli was used as the...

...Escherichia Coli People eat food every day typically without a problem. Although generally this is the result, in certain instances food poisoning develops. According to the Center for disease control (CDC), “in 2008 there were 1, 034 food born disease outbreaks” (CDC, 2011, para. 2) that resulted in sickness. Usually an individual will know if food poisoning develops. Food poisoning can cause excruciating stomach pain, uncontrollable vomiting, and annoying diarrhea. In some cases can even lead to death. In 2008 CDC statistics stated that “22 people died” (CDC. 2011 para. 2). In regard to good sense this is a relatively small number of deaths, striking is the number of reported illnesses from the outbreaks. According to the CDC “more than 23,000 people got sick during these outbreaks” (CDC, 2011, para. 2). Undoubtedly numerous food poisoning cases go undocumented. Escherichia coli (E. coli) are one bacteria agent responsible for food poisoning. So what is E. coli? What are the clinical symptoms of E. coli? What happens in an outbreak? Certainly all these questions need to be understood. Above all else Escherichia coli is preventable by taking individual and precautionary measures. All E. coli share a similar anatomy and residences prior to infection. An E. coli bacterium is approximately three microns in length excluding the flagellum. Also featured in E. coli anatomy is D.N.A, cytoplasm, and the cell membrane. Usually E. coli can be found in the intestinal track humans where...

...Escherichia Coli is a bacterium that is found in the environment and in the intestines of animals and humans. Most strains of E. coli are nonpathogenic and are important to the environment and for healthy human intestines. For the purpose of this paper, I will talk about the pathogenic E. coli, as known as diarrheagenic E. coli, that causes disease in humans. Pathogenic E. coli causes diarrhea and other intestinal problems and is transmitted through contaminated water or food, or through contact with animals or humans. (Bonenberger, n.d.)

...E-coli (Escherichia coli) is a germ that lives in the digestive system of animals as well as humans. E-coli was first isolated by Theodore Escherich a German bacteriologist in 1885 and was named after him. E-coli first became a household name during an outbreak in the western United States that began in late 1992 and lasted into 1993. Which was caused by eating ground beef. It was routinely found in the intestines of cattle companion have developed a vaccine to reduce the number of bacteria in the cattle. It has been commonly used for biological lab experiments and research. There are many types of e-coli, and most of them are harmless. Although some may cause bloody bowel movement also known as hemorrhagic diarrhea. This diarrhea illness was first recognized when the CDC personnel isolated e-coli from patients in two separate outbreak one in Oregon and the other in Michigan. The illness also was associate with eating hamburgers at a restaurant of a national chain. Some people experimented inflammation and bleeding of the colon. Infections dealing with e-coli are more common during the summer season and in northern states. Some strains of e-coli bacteria can cause anemia of kidney failure which leads to death. Other strains of e-coli can cause infection throughout the body such as the urinary tract and many more. By coming into contact with the feces, or stool of humans and animals you can get e-coli.it is normally inhabitant in small intestines and colon but do not cause...

...Outline Title: E. Coli In Ground Beef: Cause of Many Illnesses and Deaths Introduction Thesis statement: There are many cases where people have become ill and even died because of E. coli in ground beef. Body Paragraphs First supporting idea: Stephanie Smith becomes very ill after eating a hamburger in which the meat contained E. coli. Second supporting idea: Two people die after eating ground beef that may have contained E. coli linked to illness in more than two dozen people. Third supporting idea: An outbreak at Jack in the Box restaurants that killed four children. Conclusion Many people have died due to this bacteria, therefore something should be done about it. E. Coli In Ground Beef: Cause of Many Illnesses and Deaths E. coli is a bacterium that is most commonly found in warm blooded organisms. There exists several types of E. coli, many of which are not harmful to human health, except for serotype O157:H7. This serotype can cause food poisoning in humans and even lead to death in some cases. Some signs and symptoms of E. coli O157:H7 are: abdominal pain, diarrhea, nausea, vomiting, fever and fatigue. A healthy adult has a higher chance of fully recovering from this serotype within five to seven days. On the other hand, young children, the elderly and people with weakened immune systems can develop potentially fatal HUS (hemolytic uremic syndrome), a type of kidney failure. A person can be at high risk to becoming ill if they consume things...

...INTRODUCTION Mung bean (Vigna radiata L. Wilczek) sprouts can be considered one of the most common vegetables consumed in the Philippines due to availability and nutritional value (Del Rosario, 2003 and FNRI, 1997). One cup of raw mung bean sprouts contains 48 calories, 6.5 grams of protein, 1.5 grams of fat, and 5.6 grams of carbohydrate. One cup of cooked bean sprouts contains 48 calories, 6.6 grams of protein, 1.8 grams of fat, and 4.6 grams of carbohydrate. In addition, sprouts are a good source of minerals and vitamins, particularly vitamins B1, B2, and C (http://ianrpubs.unl.edu/horticulture). Mung bean sprouts are low in calories and exceptionally high in potassium. A nutritious sprouted mung bean offers the same amount of vitamin A as a lemon, the niacin of a banana, the thiamine of an avocado, the riboflavin of a dried apple, the carbohydrate content of a melon and the ascorbic acid of a loganberry (http://www.specialtyproduce.com). The sprouting process encourages the rapid growth of microorganisms that reach very high numbers in the finished product (Fu et al., 2000). Seed sprouting provides an excellent environment for the growth of many types of organisms. The release of nutrients from the sprouting seeds, the moisture resulting from the irrigation process, the aerobic conditions, pH and temperatures favorable to mesophiles all contribute to the rapid expansion of microbial population, including food pathogens, during sprouting. Population as high as...

...The results from the experiment does not support my hypothesis about the role of the FIS binding site in the rR promoter. I believed that if an E. coli strain did not have an rR promoter sequence like Strain B, or if the FIS binding sequence was completed deleted like Strain C, it will be more difficult for transcription to begin. My hypothesis was that Strain A would be the most efficient because it had a fully intact FIS binding site. Clearly, this is not the case because from the results I collected, no strain had faster gene expression after ONPG was added to each strain of E. coli. I can only conclude that some error occurred somewhere within the experiment because a logical conclusion would be that the unmutated DNA promoter should have had a stronger gene expression....

...Durning late 2015 and early 2016 Chipotle was under fire for their E. coli outbreak. “Escherichia coli, its full name, is a type of bacteria commonly found in the intestines of animals and humans. There are hundreds of strains of the bacterium, but E. coli O157:H7 has been identified as dangerous to people, producing a powerful toxin that can cause severe illness.” E. coli is caused mostly by consuming tainted or undercooked beef but can be found on any food. E. Coli in this situation is thought to have originated in beef from Australia. Because of this and improper food handling it is believe that it spread to multiple other foods. But according to chipotle no cause was found. Since then Chipotle has made many improvements to their hygiene and store cleanliness as well as safe food practices. Checking the temperature of beef to make sure that it is cooked thoroughly is the best way of eliminating E. coli. Cooking ground beef until there is no pink and steaks until 145 degrees is the safest way to eliminate E. coli. It's no secret that E. Coli isn’t fun. It lingers in your system for multiple days before symptoms show. Symptoms are mostly diarrhea that...

...Identification of Chemotaxis Protein Substrates in Thiomicrospira crunogena Introduction Thiomicrospira crunogena is a Gram negative, aquatic, colorless sulfur oxidizing, chemolithoautotrophic bacterium. Cells are spiral shaped 0.2-0.3 µm in diameter and 1-2µm long, some individual cells can reach up to 30 µm long (3). T. crunogena is motile via a singular polar flagellum. It is the first deep-sea autotrophic hydrothermal vent bacterium to have its genome fully sequenced and annotated (1). Originally isolated from the East Pacific Rise, it is commonly isolated from deep-sea hydrothermal vent communities where warm, CO2 rich hydrothermal fluid that surges from cracks in the basal crust mixes with cold, oxic bottom water (1). This mixture creates eddies, or whirling of water similar to a vortex where the dilute hydrothermal fluid causes a dynamic habitat with respect to time and nutrient concentrations. The warm hydrothermal fluid emitted from the fissures contains CO2 concentrations between 0.02 mM to >1 mM where as the bottom water is around 2°C and contains CO2 concentrations less than 0.02 mM (1). This difference in CO2 concentration, temperature and oxygen concentration causes T. crunogena to be just as dynamic metabolically in order to survive in an ever-changing environment. As previously mentioned, T. crunogena is a chemolithoautotrophic bacterium deriving it’s energy from inorganic compounds such as hydrogen sulfide, thiosulfate, elemental sulfur...
