Clostridium Difficile Tiffany Hoang Health Science Technology 03/03/2016  Clostridium Difficile Clostridium difficile also known as C. diff is a disease caused by a germ which in the United States infected half a million people in 2011, and twenty nine thousand people that died within thirty days. Patients with this disease have symptoms such as watery diarrhea, fever, loss of appetite, nausea, and abdominal pain. Usually, people who are at increased risk for C. diff had gastrointestinal…

that can be contracted by puncture wounds to the human flesh is tetanus, commonly known to the public as lockjaw. The disease tetanus is a serious infection from the bacterium Clostridium tetani. This bacterium produces a toxin that affects the brain and nervous system that leads to stiffness in the muscles. The Clostridium tetani produces neurotoxins that interfere…

specialized function that select bacteria undergo when they are exposed to harsh environmental conditions (Fimlaid 2015). Clostridium difficile, Clostridium botulism and Bacillus anthracis are three examples of sporulating bacteria that cause serious human disease. In a 2011 study, the Centers for Disease Control and Prevention estimated that there are 453,000 cases of Clostridium difficile, with 29,300 associated deaths (Roos 2015). The impact these bacteria have on the human population is not…

•Researchers’ question: Do lifestyle and dietary habits change the gut microbiota in obese individuals? •Hypothesis (and possible predictions): Gut microbiota changes along with the body composition in obese individuals during weight loss. The possible prediction is that gut microbiota changes before, during and after losing weight. •Experiment and variables: Obese individuals were subjected to a dietary regimen during 4 months. The experiment consisted in measuring BIA and gut microbiota before…

One third of our composition of the gut microbiota resembles to our parents composition of microbiota. But after being born, the 2/3rd of our composition of our microbiota is dynamic up until the age of 3. There are several factors that affect the composition of the gut microbiota throughout our lives but it is most effective on newborns. The first factor that affects the composition of the microbiota is how the baby is delivered. (2) Vaginally delivered babies are colonized by vaginal microbes…

Tetanus is a very serious bacterial disease that causes many muscle spasms and breathing problems. The bacterium that causes tetanus is called Clostridium tetani. Clostridium tetani is the bacteria that produces toxins that affect the nervous system. Around one in 10 people infected with the bacterium that causes tetanus will die from it. A tetanus bacterium enters the body through a puncture wound, which can be caused, by nails, insect bites, burns, splinters or injection drug sites. These…

1.7.3.4. Hydrogen sulphid test (MacFaddine, 1980): Tubes of triple sugar iron agar media were inoculated by suspected culture through stabbing into the butt and the slant then covered with sterile melted paraffin wax and incubated anaerobically for 48 h at 37°C, appearance of blackening in the butt indicates H2S production. 1.7.3.5. Sugar fermentation test (Willis, 1977): Suspected culture was inoculated to 1% peptone water tubes containing 2% bromocresol purple and 1% quantities of the…

1. A 39 year old US postal worker notices an area of redness and swelling on his left lateral forearm. Six days later he notices that the rash, which is painless, now appears black and swollen. He becomes concerned and goes to the emergency department, where he is subsequently diagnosed with cutaneous anthrax. Which of the following mechanisms is most likely associated with the swelling that surrounds the black rash? A. SNARE protein cleavage B. Overactivation of adenylate cyclase by disabling…
