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
The Insecticide Bacillus Thuringiensis What is this Bt toxin that is in the food we eat? Bacillus thuringiensis is an insecticide with unusual properties witch make it very useful for pest control in certain situations. Bacillus thuringiensis is a naturally occurring bacterial disease in some insects. It is very common in the soils around the world. There are many strains of Bt that can infect insects and kill them. The Bt toxin has been developed because of this unusual property. The insecticidal
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

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
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
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
purple colouring at the end of the Gram stain procedure. This implies that the bacteria had only one cell layer, which absorbed the crystal violet stain. Therefore, the microorganism is gram positive, and based on the morphology, the microorganism is Bacillus cereus (Brooks et al. 2013).b. Describe two ways the food(s) could have become contaminated. Food gets contaminated in several ways. Notably, all hands look clean but may still harbour bacteria. Uncovered coughs as well as sneezes may cause the spread
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

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
The Stolen Bacillus by H.G. Wells This is a story set in the 19th century people had dress codes which reflected your status in society. The dress code was formal and quite severe it was almost as if the longer your top hat the higher up the rank you are in importance in society. In this story we meet a man who wants to help the society and quality of living whereas the other wants to destroy order as he is what’s known as an anarchist. This is someone who is feels that people should be
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
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
Clostridium perfringens, formally known as C. welchii or Bacillus welchii, is a gram-positive, rod-shaped, anaerobic, spore forming bacterium. The first association C. perfringens had with gastrointestinal disease was in the 1920s (Songer, 1996). The next case was post-World War 1, in Germany, in the 1940s, when it caused gangrene of the bowel, enteritis necroticans. Since then, C. perfringens has been the most commonly associated with gas gangrene (Lawrence et al., 1997). In 1950, there was a confirmed
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

This specific BT gene harvest a toxin that restricts insects, and the genetically engineered BT plants and therefore, able to create their own

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)
negatively affected our way of living. The assumption that GMOs are causing a variable of health problems holds no credible scientific evidence. There is proof, however, in developing countries like India genetically modified crops like cotton containing bacillus thuringiensis, or Bt have resulted in higher yields and profits for the poor farmers. Thanks to its resistance to bollworm farmers using Bt cotton can save money on herbicides, saving more money for food and education. Many of the GMOs have been

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
