Bacteriology (late 19th discovery of bacteria with light microscope)-Pasteur, Koch, and Lister founded the artificial lake theory of disease which states what specific microorganism ca examples a disease. Virology (1930s, discipline of ECM (100,000x) allowing vision of the first virus (Yellow Fever) Immunology-1960s immunity is vindication and demur against dangerous microbes or their toxins. Vaccines be used to roseola this defense response and prevent any(prenominal) further contagion by generating a host defense response. An innate immunity is present at birth and be of anatomical barriers (skin which is fat and mucous membranes which are thin), lysozymes that lyse bacteria and are found in proud concentration of tears, the stomach gastric acid of pH1-2, and cilia which use a sweeping motion in the lungs to brush remote trapped bacteria in mucous membranesthis can be slowed in cold temperatures increasing chances of pneumonia. Serology is the gui de of serum usage. serum is plasma without the components of clot, which can be degage by centrifugation. serum antibodies are clues to infections that a person has already had. A diagnostic test detects the antigen via the antibody reaction and are cognize as serological test.

Antigens and antibody reactions have a very high specificity allowing these test to testify the results of the infection. Two major areas of Immunology are molecular immunology (protein chemistry) and cellular immunology. cellular immunology contains lymphatic system (drain tissue peregrine into lymph nodes), phagocytosis, and lymphokines (chemical mediators of the c! ell arbitrate immune response) which are mostly produced by thymus delay hypersensitivity cells Tdh. Adaptive Immune System (disease armed combat mechanism against microorganisms and neoplasm cells) Two branches: Humoral Immunity and cellular Humoral Immunity is antibody mediated with five different antibody classes (IgM,IgA,IgD,igG,igE) Ig=immunoglobulinda Gamma globulin is found in...If you want to labor a full essay, request it on our website: OrderCustomPaper.com
