Neutralizing antibodies are effective at preventing infection or toxicity mediated by pathogens or their toxic products. In fact, nearly all vaccines currently in use function by eliciting neutralizing antibodies. One example is the tetanus vaccine, in which neutralizing antibodies are generated against an inactivated form of the tetanus toxin (the tetanus toxoid). The most important feature of a neutralizing antibody is having high affinity for the antigen. being efficient at activating the complement cascade. having a high degree of multivalency, such as being a pentamer or hexamer of immunoglobulin monomers. being present at a high concentration in the circulation. 0 0 0 0

55.  Identify a MISMATCHED pair from the following,  Group of answer choices lethal factor :::: protease activity; inhibits chemokine production. edema factor :::: unregulated cAMP synthesis protective antigen ::::  binds and assembles at target cell membrane protective antigen :::: acts as a biosensor ; detects higher temperature of the digestive system to become active protective factor :::: aids in bringing other toxins components inside cell via endocytosis     56. Which of the following holds TRUE for blood agar medium? Group of answer choices gamma hemolysis is when there is no effect on red blood cells. alpha hemolysis is due to complete breakdown of red blood cells beta hemolysis is the incomplete breakdown of red blood cells. we always use human red blood cells in blood agar blood agar medium belongs to selective media

In the antibody-mediated immune response, the binding of some antigen-presenting B cells to helper T cells initiates a signal transduction pathway that transforms the B cells into plasma cells, which will synthesize and secrete large quantities of antibodies-a specialized subset of proteins responsible for attaching to the antigen on the outer surface of pathogens. Which of the following describes the most relevant intracellular change to B cells as they are transformed into plasma cells? A B a breakdown of some membrane-bound proteins to allow synthesized antibodies to more readily diffuse across the membrane of the plasma cell с an increase in the surface area of the rough endoplasmic reticulum in order to allow the binding of a large number of ribosomes for antibody synthesis D an increase in the number of lysosomes in order to facilitate the storage of synthesized antibodies ahead of their transport out of the cell an increase in the volume of the mitochondria in order to increase…

Cow's milk allergy (CMA) and lactose intolerance both result from dietary exposure to cow's milk and are often confused. CMA is caused by an abnormal inflammatory response to one or more proteins in cow's milk. Although more than one mechanism. appears to be involved in generating this response, the antibody- mediated response is the best understood. Development of the antibody-mediated response occurs in two stages, the first being the generation of an abnormal immune response during initial exposure to milk proteins and the second being the generation of an inflammatory response upon subsequent exposure. Symptoms of antibody-mediated CMA may include hives and respiratory difficulty. Anaphylactic shock rarely occurs but can be fatal if not treated immediately. Lactose intolerance, also known as lactase deficiency, is a condition that results from insufficient synthesis of the enzyme lactase, which converts lactose into glucose and galactose. Although all healthy newborns produce…
