  • Immunology is the study of defensive responses to foreign invaders called antigens. Defense responses can be either nonspecific or specific. Nonspecific responses are innate and constantly operating all brawn and no brain. Specific responses develop after nonspecific responses and are directed specifically at the antigen the brains of the operation. Practice: Which one of the following describes a specific immune response? Secretion of an antibody by a B-lymphocyte B. The specific immune responses are divided into either humoral or cell-mediated responses. Humoral immune responses involve the production of antibodies by B-lymphocytes and the cell-mediated immune response involves the destruction of "self cells gone wrong" tumor cells, parasitized cells, transplanted cells by T-lymphocytes. Remember that an antibody is a glycoprotein that reacts specifically with a particular antigen and tags it for removal or destruction! Antibodies are bivalent, Y-shaped molecules.

Serology is the science of detecting and measuring antigen-antibody reactions. Precipitation - A bivalent antibody reacts with a multivalent antigen that is soluble e. A precipitation was formed in the Ouchterlony gel diffusion experiment. Agglutination - A bivalent antibody reacts with a multivalent antigen that is insoluble: particulate or cellular e. An agglutination is demonstrated by hemagglutination seen in blood typing. Blood typing 1. Type A blood cells, have on their surface, a type A antigen. A person with type O blood has no antigens on its surface.

Be able to determine the blood type of a person by looking at a blood typeing tray in which the blood has been mixed with antibodies to A, B and Rh antigens.

The first stage is the quantitative stage, the other two are merely confirming that a coliform has been identified. Stage 1: The presumptive test 1. Three sets of three lactose broth tubes are inoculated with either 0. Know how to interpret, determine a profile and use the MPN table. Realize that this is less accurate than the membrane filtration method. Stage 2: The confirmed test - An EMB plate is streaked from one of the lactose broth tubes showing a positive result.
