A person develops an infection from a bacterium. Describe what is going on with regards to non - specific and specific immunity during the incubation period and prodromal phases. Why is the non specific response so important if the specific immune response should eliminate the bacterium?
Homework Answers
Answer:
In case a person develops an infection from a bacterium, the first and second line of defense comes into action, that is, the innate immune system. It happens during incubation and prodromal period. The innate immune system provides a non-specific immunity, It means that the immune cells respond not only to one kind of antigen but to all types of antigens/foreign substances that enter our body. It is a kind of natural immune system. After this comes the third line of defense, which is, specific immunity.
In a specific immune response, the antibodies specific to particular antigens are developed by the immune cells. These antibodies further help in the elimination of the antigens to which they are specific.
The reason why the non-specific immune response is important is that it comes into action quicker than the specific immune response. The specific immune response takes time to develop and meanwhile there should be some mechanism to provide protection against any antigen/pathogen. This first line of the defense is provided by the non-specific immune response.

How can the immune system orchestrate protection from disease without killing us in the process IQ4: Homeostasis: A balance of the good and bad B- and T-lymphocytes are derived from bone marrow- derived lymphoid precursors. Before maturation, naive T-lymphocytes (T-cells) must pass through the thymus where they undergo positive and negative selection. A tumour encounters the immune system frequently during its progression from a neoplasia to carcinoma, which can often take several years. There are a number of host mechanisms...

You are a T-helper cell in your immune system and are deciding what parts of the immune system to marshall against an incoming invader. For this assignment, you will be presented with a pathogen and its arsenal of virulence factors that it can use against you. Your job, if you choose to accept it, is to pick the portions of the immune system that you will use against each virulence factor and then describe how that immune system part inactivates...
