Bacillus anthracis (anthrax) is a bacterium that infects organisms through sporulation. Bacillus anthracis is can be aerobic (needs oxygen) or, facultative anaerobic (does not require oxygen). It is also a gram positive bacterium that can be found in the soil of humid and damp climates (Hicks, 2012). The bacterium is part of the species Bacillus Cereus (Koehler, 2009). It is known to infect life forms four different ways. Infection can be caused through digestion, eating food that is contaminated
mad scientist developed in a lab in hopes of taking over the world. In reality is an ancient disease of live stock and humans known since Biblical times. It just never made so many headlines before. Anthrax is an infectious disease known as Bacillus Anthracis. The bacterium can survive for centuries in a spore form. Their inside coating of armor allows the bacteria to exist in the soil or float about in the air until it finds a host to infect. Symptoms of the disease vary depending on how the disease

Cause of Disease Anthrax I an infectious disease that is caused by bacterium bacillus anthracis. bacillus anthracis is a Gram-positive. A “Gram-positive bacteria are bacteria that give a positive result in the Gram stain test, which is traditionally used to quickly classify bacteria into two broad categories according to their cell wall” as cited from https://en.m.wikipedia.org/wiki/Gram-positive_bacteria. Bacillus anthracis is also an Endospore-forming, rod shaped bacterium, with a width of 1.0 to
Anthrax is a very real and dangerous threat to all people who come in contact with it. The bacterial infection is caused by the bacteriaium Bacillus anthracis. Anthrax is divided into three categories all are contracted in different ways. The first type is called Cutaneous Anthrax; this is where anthrax spores make contact with the skin. If there is a cut or a lesion then a person can be infected. Cutaneous Anthrax is the most common way to get anthrax, but is also the least lethal. The second type
You’ve Got Mail “One Friday night my throat began to swell up. A cold, I thought. But it worsened over the weekend. My glands were soon enormous. Monday morning came and my face was barely recognizable (Chamberlain).” Anthrax is a rare bacterial disease that affects the skin and lungs. On September 18th 2001, letters containing lethal amounts of anthrax were mailed out. The deadly anthrax letters were sent out to people all over the United States. Even though the disease was not widely spread
Anthrax is a bacterial disease caused by bacteria called Bacillus anthracis (buh-SIL-us an-THRAY-sus). The Bacillus anthracis can exist in two different forms: favorable form, when the bacteria are rod-shaped and can grow and divide, or the unfavorable form, when they form a very resistant dormant spore that helps them survive extreme environmental conditions. Like other bacteria, Bacillus anthracis is very small, only about 1 by 9 micrometers in size. It is Gram-positive, which makes the bacteria

Every organism requires a specific environment in order to survive. Bacteria alike, different types of bacteria are able to survive and reproduce in different types of environment. Some factors that affect the growth of bacteria include temperature, presence of certain gases and pH of the medium it is in. In this experiment, the variable that was changed was temperature. Temperature is one significant factor that affects the growth of bacteria. Each bacterial culture has its own minimal, maximal
and bacterial culture. Problem statement Do antibiotics have the same effect on killing different types of bacteria? Abstract: The main objective of this experiment is to investigate the effect of different types of antibiotics on bacteria Bacillus subtilis and Escherichia coli. Some of the main methods used in this experiment includes: the using of aseptic techniques for the preparation of agar plates. Paper discs containing different types of antibiotics then placed on the hardened agar
known as alternation of generations. Type of bacterial spores Endospores Endospores, are powerful against harsh chemical and physical conditions. This gives the ability to the bacteria to resist disinfectants, radiation, desiccation and heat. Bacillus are a big reason for food and medical contamination and are often difficult to get rid of them. endosporulation process start When a bacterium detects unfavorable environmental conditions, which takes eight hours long. The DNA is replicated and
Comparing the Narrative Skills in The Stolen Bacillus by H.G. Wells and Hop Frog by Edgar Allan Poe Works Cited Missing In the nineteenth century, short stories became more and more popular, especially to the working class people. As they had limited spare time, they were attracted to short stories rather then long novels. The technology of printing in the nineteenth century enabled large number of books , magazines and newspapers to be printed not only cheaply but quickly and of a good
rendering highly resistant bacterial spores biologically inert. The highly resistant bacterial spores used varies depending on what kind of sterilizer was used. For example Bacillus stearothermophilus spores for steam and chemical vapor sterilizers, Bacillus subtilis spores for dry heat and ethylene oxide sterilizers. These specific Bacillus spores are used because they are more resistant, and present in greater numbers than are the common microbial contaminants found on patient care equipment. If it is
The most wonderful activity a human being can experience is new flavors and foods. For example, the first time a person tastes a delicious juicy piece of prime rib or a delightful hamburger with cheese and ham, his world is never the same. However, since the beginning of the twentieth century, the production of food has been supplemented by science. This has triggered an angry dispute between the people who support the advances of biotechnology and people who love nature. In order to understand the
“Genetically modified foods are a "Pandora's box" of known and unknown risks to humans and the environment. They have been forced onto the American public by multinational biotech and agribusiness corporations without adequate oversight and regulation by the United States government (Driscoll, SallyMorley, David C).”Genetically Modified Food is food which has been chemically altered by scientists during the production process to give the food more nutrients, better appearance, and a longer shelf-life

This specific BT gene harvest a toxin that restricts insects, and the genetically engineered BT plants and therefore, able to create their own
Scientists have been changing genomes of plants and animals by integrating new genes from a different species through genetic engineering, creating a genetically modified organism (GMO). Consumers in America have been eating GMOs since 1996, when they went on the market. There are benefits to genetically modifying crop plants, as it improves the crop quality and increases yield, affecting the economy and developing countries. But there are also negative effects from GMOs. Consumption of GMOs has
Monsanto which is located in 6 continents and 68 countries is the biggest seed company of the 21st century. Monsanto was founded in 1901, St. Louis, Missouri, United States by John Francis Queeny. Likewise, Monsanto Headquarters are currently located in St. Louis, Missouri where founded. Monsanto had about 20,600 workers in 2011. Hugh Grant, the current CEO of Monsanto, has been in this position since 2010. He has a salary of about f $1,391,356 per year excluding his additional profits. The three
to the crop; therefore, cotton has been genetically modified to produce specific toxins for insect tolerance, this is called BT toxin. BT cotton is a type of transgenic cotton containing a protein induced from the gene of soil bacterium named as Bacillus thuringiensis (BT). Genes encoded for proteins were incorporated into cotton plants by Monsanto, an American agricultural biotechnology corporation. In 1980, Monsanto identified and extracted BT genes, the gene encoding for BT protein (Cry1Ac)
than pesticides in reducing Corn Borers. There exist many benefits and drawbacks to the use of Bt corn. Bt corn is a form of corn where Bacillus thuringiensis, a bacteria, is transplanted into the corn as a form of pesticide. Ric Beesin, an entomologist at the University of Kentucky, claims “A donor organism may be a bacterium... In the case of Bt corn… Bacillus thuringiensis, and the gene of interest produces a protein that kills Lepidoptera larvae… Growers use Bt corn as an alternative to spraying
