airborne transmission

• a transmission mechanism in which the infectious agent is spread to an aerosol and usually enters a person through the respiratory tract

• immune mechanisms that "learn" to deal with specific invaders

• a group of immunocompetent cells that mediate cellular immune response by engulfing, processing, and presenting antigens to the T-Cell receptor

• a substance produced by a B lymphocyte in response to a unique antigen, which it can then combine with to destroy or control it

biological vector

• a vector that is essential in the life cycle of a pathogenic organism

• a type of lymphocyte, developed in bone marrow, that circulates in the blood and lymph and, upon encountering a particular foreign antigen, differentiate into a clone of plasma cells that secrete a specific antibody and a clone of memory cells that make the antibody on subsequent encounters

• a semi-permeable phospholipid bilayer that separates the interior of cells from the outside environment and controls movement into and out of the cell

• a sheath or continuous enclosure around an organ or structure

B cells

• a vector that is essential in the life cycle of a pathogenic organism

• a type of lymphocyte, developed in bone marrow, that circulates in the blood and lymph and, upon encountering a particular foreign antigen, differentiate into a clone of plasma cells that secrete a specific antibody and a clone of memory cells that make the antibody on subsequent encounters

plasma membrane (cell membrane)

• a vector that is essential in the life cycle of a pathogenic organism

• a type of lymphocyte, developed in bone marrow, that circulates in the blood and lymph and, upon encountering a particular foreign antigen, differentiate into a clone of plasma cells that secrete a specific antibody and a clone of memory cells that make the antibody on subsequent encounters

capsule

chromosomes

• a linear strand made of DNA that carries genetic information (genes)

• threadlike projections from the free surface of certain epithelial cells used to propel or sweep materials across a surface

• occurs when microorganisms are transferred from one infected person to another

• the mode of transmission of infectious pathogens from a source that is common to all the cases of a specific disease, by means of a vehicle such as water, food, air, or the blood supply
