8. Pigment or color (e.g.: opaque, translucid, red, yellow, rose, violet, etc..) is also
another characteristic that can be used to identify your microorganism in a slant
Thus, write down the name of three microorganisms (using scientific notation:
Escherichia coli) that present a pigmented pattern of growth in a slant (write down
the color of each pigment) and the name of the disease that they may cause.

Why 70% alcohol is used as a disinfectant? Circle all possible explanation.
O A. Alcohol denatures proteins in the plasma membrane or viral body thus destroying it rendering them ineffective and
causing cell death or inhibiting reproduction.
V B.
Water is used as a catalyst for the denaturation of proteins that leads to cell membrane destruction.
O c.
Alcohol can be taken in orally, destroys cells that entered the body.
V D.
Diluted alcohol evaporates slower compared to a pure alcohol since its highly volatile, providing more time for chemical
reactions to take place.
O E.
100% alcohol coagulates proteins instantly creating a film that protects the other proteins from further coagulation
preventing other alcohol molecules to react and destroy the cell membrane.
O F.
Alcohol has a dehydrating effect and may interfere with the functioning of cell membranes.

- 1. Select one microorganism (a prokaryote, protest, or fungus) which has the potential to be used for bioterrorism. This microorganism should normally be pathogenic (meaning it causes disease in those that are exposed to it). 2. Design an infographic to show how the microorganism infects human/animal cells. This infographic should include all stages of the life cycle of this microorganism. May choose to create your infographic by hand or use digital tools such as Canva, Piktochart, Visme, Google Drawings, Microsoft word, or any other platform familiar with. 3. Write a fictitious letter to the government to explain how this microorganism can be destroyed/prevented. The intervention(s) that is/are chosen should be based on research and be applicable to a large - scale implementation strategy (i.e., if a bioterror microorganism kills all livestock to reduce protein supplies, then the intervention should be easily supplied to the livestock, such as in their water/food supply, to prevent…arrow_forward1.The study of Introduction to Microbiology showcases the enormous impact of microbes on living organisms and the environment at large.

- There have been recurring cases of mad-cow disease in the United Kingdom since the mid-1990s. Mad-cow disease is caused by a prion, an infectious particle that consists only of protein. In 1986, the media began reporting that cows all over England were dying from a mysterious disease. Initially, there was little interest in determining whether humans could be affected. For 10 years, the British government maintained that this unusual disease could not be transmitted to humans. However, in March 1996, the government did an about-face and announced that bovine spongiform encephalopathy (BSE), commonly known as mad-cow disease, can be transmitted to humans, where it is known as variant Creutzfeldt-Jakob disease (vCJD). As in cows, this disease eats away at the nervous system, destroying the brain and essentially turning it into a spongelike structure filled with holes. Victims experience dementia; confusion; loss of speech, sight, and hearing; convulsions; coma; and finally death. Prion diseases are always fatal, and there is no treatment. Precautionary measures taken in Britain to prevent this disease in humans may have begun too late. Many of the victims contracted it over a decade earlier, when the BSE epidemic began, and the incubation period is long (vCJD has an incubation period of 10 to 40 years). A recent study concluded that 1 in 2,000 people in Great Britain carry the abnormally folded protein that causes vCJD. In spite of these numbers, the death rate from vCJD remains low. It is not clear whether this means that the incubation period for the disease is much longer than previously thought, or whether they may never develop the disease. If you were traveling in Europe, would you eat beef? Give sound reasons why or why not.arrow_forwardThere have been recurring cases of mad-cow disease in the United Kingdom since the mid-1990s.
