Broad-spectrum antibiotics have an advantage over narrow-spectrum antibiotics in that they can act on a broader range of pathogens. What advantages to narrow-spectrum antibiotics have over broad-range ones? Please mention three (3). Metabolically speaking, how come antibacterials cannot be used against viruses? How come antivirals cannot be used against bacteria? What parts of the immune system belong to both the innate and the acquired response? Why are they listed twice? How do B-cell activation and t-cell activation differ? How are they similar? What vaccines come in both Live, Attenuated and Inactivated versions for specific pathogens? For each pathogen where this is the case, which type of vaccine is preferred and why. (This may require a little more research than usual.) List seven (7) ways that pathogens can evade host defenses. List three (3) hospital procedures that are most likely, despite protective measures, to lead to Health Care-Associated infections (or, as the older texts would say, Nosocomial Infections). In a "regular hospital", what patients would require the most layers of PPE and why.
