The reason as to why a speck of dust landing on the skin does not lead to an innate immune response, while a bacterium does. Introduction: The immune system can be divided into innate immunity and the adaptive immunity. Innate immunity is referred as the first line of defense and mainly includes physical and chemical barriers. It is nonspecific and acts on all potential harmful invaders without discrimination.

The immune system can be split into two major categories, the innate immune system and the adaptive immune system. Compare and contrast these two systems and their response to a bacterial pathogen that entered the body through a cut in the skin. In your answer describe two ways in which the innate immune system protects against this pathogen, as well as two ways that the adaptive immune system protectS against this pathogen. Be sure to name any cells/organs/tissues/structures that may be involved in each of these processes in order to receive full marks. This can be done as a list in point form.

This week you learned about the role that macrophages, neutrophils, and cytokines play in the innate immune response and looked at how they contribute to the development of inflammation and the inflammatory and the acute phase response. In certain bacterial illnesses, particularly lung infections with Pseudomonas aeruginosa, a physician may not treat the patient with antibiotics (which will kill the microorganisms), but rather give the patient anti-inflammatory medications. Why might a physician choose to inhibit inflammation in the case of an infection? What types of damage might the inflammatory response do to the surrounding tissues, not just the bacteria it was designed to combat?

In Lubeck, Germany, in 1930, a group of 251 infants was accidentally administered a tainted vaccine for tuberculosis that contained live Mycobacterium tuberculosis. This vaccine was administered orally, directly exposing the infants to the deadly bacterium. Many of these infants contracted tuberculosis, and some died. However, 44 of the infants never contracted tuberculosis. Based on your knowledge of the innate immune system, what innate defenses might have inhibited M. tuberculosis enough to prevent these infants from contracting the disease?
