Hay fever, also called allergic rhinitis, is a common ailment in the spring. People who experience hay fever have sensitive immune systems that respond to pollen in the air. When pollen, the allergen, enters the airways, the inflammatory response is triggered, even though pollen is not a dangerous molecule. Symptoms include inflammation of the airways, nasal congestion, and watery eyes. While there is currently no cure for hay fever, people suffering from it often take antihistamines, medications that inhibit the action of histamine. How would this help the condition? 2.

If a cut or scrape becomes infected, Staphylococcus aureus is probably the culprit (right). These bacteria often live on the skin and they can cause a problem if they get into a wound. Most staph infections can be cured with the antibiotic methicillin. Unfortunately, methicillin-resistant S. aureus (MRSA) is on the rise. Previously, antibiotic-resistant staph infections occurred mainly in hospitals and nursing homes. Now they are breaking out in schools and health clubs. The bacteria are transmitted by contact with an infected person or something that person has touched, as by sharing towels and razors. The gene conferring methicillin resistance is on a plasmid. Explain why a gene that is on a plasmid can spread more quickly than one on the bacterial chromosome.
Part B: Antifungal agents are less selectively toxic than antibacterial agents meaning that they cause more damage to the host cells. Why is that the case?
