the ABO blood group system. Although simulated blood was used for the experiment a standard blood typing outcome was still obtained. After conducting the experiment I was able to identify each patients blood type by comparing the antigens and antibodies found within the blood. Materials and Methods Simulated blood‚ plastic slides‚ and antiserum were the materials used to perform this experiment. In order to specify each patients blood type it was necessary to place two drops of the simulated

Active Immunity The production of antibodies against a specific agent by the immune system is known as active immunity. This particular immunity process is there to keep you healthy. Active immunnity can be acquired in two ways: naturally by contracting an infectious disease or artificially by receiving a vaccination. Active immunity is natural and permanent; protecting individuals from disease their entire lives. This process can take place quickly by large amounts of medicines at one time

class of syphilis diagnostics that detect infection by indirect markers of infection. Nontreponemal Tests detect biomarkers that are released during cellular damage that occurs from the syphilis spirochete. In contrast treponemal tests look for antibodies that are a direct result of the infection thus‚ anti-treponeme IgG‚ IgM and to a lesser degree IgA Non Treponemal Non-treponemal serologic tests for syphilis include VDRL (Venereal Disease Research Laboratory) test and RPR (Rapid Plasma Reagin)

immunoglobulins and for short we will use Ig. The five main antibodies are IgA‚ IgM‚ IgE‚ IgD‚ and IgG‚ this document focuses mainly on the IgG immunoglobulin. Let’s first look at what the five immunoglobulins do. The IgA immunoglobulin protects body surfaces exposed to the outside‚ so this would be your skin‚ the body’s first defender. IgM immunoglobulins which are the largest in size of all the immunoglobulins‚ are the first antibodies made in response to infection. The IgE immunoglobulins are involved

Proteins The three major types are the albumins‚ globulins‚ and fibrinogen. Most are made in the liver‚ except antibodies which are produced by B lymphocytes. Have many functions that help maintain homeostasis: Buffer the blood and keep the pH around 7.4. Contribute to osmotic pressure which keeps water in the blood –– Albumins. Transport large organic molecules. Antibodies help defend the body against disease –– Gamma Globulins. The plasma protein fibrinogen is important in the process

either antibody-dependent or antibody-independent mechanisms‚ or by use of both (2). Congenital deficiencies of the complement pathway‚ such as missing factor C2 or C3 in either the classical or the alternative pathway can put people at higher risk for invasive infection by S. pneumoniae‚ as the factors in effective opsonisation of the bacterium are missing and therefore the microorganism in question – S. pneumoniae in this case – cannot be phagocytosed (2). The lack of certain antibodies‚ as discussed

have many different antigenic determinants and may therefore cause the formation of more than one antibody. Chapter 21.4 Quiz 1. Some immunocompetent cells will never be called to service in our lifetime. True 2. Adaptive immunity is provided only by lymphocytes that secrete antibodies. False 3. Somatic recombination by B cells allows each B cell to form its own unique antibody genes. True 4. It is our genes‚ not antigens‚ that determine what specific foreign substances
