Elaine was enjoying a pleasant day on the ski slopes at Winter Park. When she got on the lift to the top of Parsenn Bowl (12,000 ft), the weather was fine—windy, but sunny. During the 5- or 10-minute ride, the weather changed suddenly; it became a white-out, with icy surface snow, blowing snow, a very strong wind, and extremely low visibility. Many people fell as they got off the lift, including Elaine. However, she got up and joined her family members as they stood, wondering just how they were going to get down the mountain. Meanwhile, the lift closed due to the terrible conditions (50-mile-an-hour wind and a temperature of −20° F). As she adjusted her stance, Elaine somehow twisted and fell again, which resulted in external rotation of her right knee. There was no pain at the time and she thought she could get up and prepare to get down the mountain, but her knee was too unstable. While she sat on the icy surface, her husband notified the lift operator to call the Ski Patrol. In about 20 minutes they arrived and put her on a sled, which they skied down the slope; when they reached the Ski Patrol headquarters, they transferred the sled to a snowmobile and promptly got her down the mountain and into the emergency room.

Develop a simple experiment to test the given microbes in the various salt solutions and include a method to determine growth. Predict the results of your experiment. You are provided nutrient broth cultures of the following microbes: Escherichia coli, Staphylococcus epidermidis, and Halobacterium salinarium.

The availability of water is defined by a physical parameter called the water activity, Aw. It is determined by measuring the ratio of the water vapor pressure of a solution to the water vapor pressure of pure water. The values for water activity vary between 0 and 1.0, and the closer the value is to 1.0, the more water is available to a cell for metabolic purposes.

Your goal is to design a vaccine that will protect vaccinated individuals from disease caused by the infectious agents listed below. This does not always mean you need “sterilizing immunity” (protection from infection), although in some cases this might be your goal.

Tetanus: Tetanus is caused by an infection with the bacterium Clostridium tetani, commonly found in soil, dust, and manure. Spores of the C. tetani can remain infectious for more than 40 years. You can get tetanus when the spores enter your body through an injury or wound, especially via a contaminated object. C. tetani produces a toxin that interferes with muscle contractions, resulting in the symptoms that can lead to permanent contraction (lockjaw) and death. The agent does not spread between people.
