Immune System Terms Name: _____________________________________________ Date: _________ Class: _________ Define the following terms: allergy, antibiotic, antibody, antigen, bacillus, binary fission, capsid, cell mediated immunity, coccus, conjugation, disinfectant, endospore, fever, germ theory of disease, heterotroph, histamine, inflammatory response, interferon, Koch’s postulate, pathogen, photoautotroph, prion, sprillium, sterilization, toxin, vaccination, vector, virus Idea that infectious diseases are caused by microorganisms, or germs. 1. The same pathogen must be present in every case of disease 2. The pathogen must be isolated from the diseased host and grown in a pure culture. 3.The pathogen must be isolated from the inoculated animal and must be shown to the be the original microbe. A harmful substance produced during the metabolism and growth of certain microorganisms and some plant and animal species. a carrier, especially the animal (usually an arthropod) that transfers an infective agent from one host to another Nonspecific defense against infection, characterized by redness, heat, swelling, and pain A rise of body temperature above the normal. It is caused by cytokines produced in response to infection. A protein released by infected cells, that has the property of inhibiting virus replication A protein that, when introduced in the blood, triggers the production of an antibody immunity against abnormal cells and pathogens inside living cells A protein that acts against a specific antigen An injection that produces a mild form of a disease in order to help build up an immunity to it. A chemical released by the body during an inflammatory response that causes the blood vessels to dilate a damaging immune response by the body to a substance, especially pollen, fur, a particular food, or dust, to which it has become hypersensitive A rod-shaped bacterium. A spherical bacterium. spiral shaped bacteria An organism that harnesses light energy to drive the synthesis of organic compounds from carbon dioxide. organism that makes organic carbon molecules from carbon dioxide using energy from chemical reactions organism that is photosynthetic but needs organic compounds as a carbon source A form of asexual reproduction in which one cell divides to form two identical cells In bacteria, the direct transfer of DNA between two cells that are temporarily joined. An organism that causes disease A chemical that kills bacteria or slows their growth without harming body cells. A process that destroys all microorganisms, including spores and viruses A chemical agent that is used to destroy bacteria and viruses on surfaces ultramicroscopic infectious agent that replicates itself only within cells of living hosts Outer protein coat of a virus -Infectious protein
