Final Review For Microbiology 1. Define Vectors - An agent usually an insect or other animal able to carry pathogens from one host to another. Also, A genetic element able to incorporate DNA and cause it to be replicated in another cell. -Passive transfer rather than actively growing population in case of reservoirs. (Living) ex. Fleas (spraying can be helpful) some cases need specific mosquito. Epidemiology -The study of the occurrence, distribution, and control of diseases. The study of disease in a population, distribution, spread, and control of spreading. Zoonosis - A disease primarily of animals that is occasionally transmitted to humans. Ex. Rabies, Plague, anthrax. Animal reservoir - Sites in which viable infectious agents remain and from which infection of individuals may occur. Carrier - an individual that harbors infectious organisms but does not show symptoms of disease. Ex. Hospitals: Staph. aureus. Typhoid fever ( Salmonella typhi) (1906). Doctors could be carriers. Etiology - refers to the causes of diseases or pathologies. Explanations for certain diseases. Bacteremia - The transient appearance of bacteria in the blood. Fomite - Inanimate objects that, when contaminated with a viable pathogen, can transfer the pathogen to a host. All nonliving –droplet infections-copper in brass kills bacteria/ so does silver but silver is more expensive. Antibody titer - In immunology the quantity of antibody present in a solution. Can test to see if a person has antibody specific to a disease. Precipitin reactions - (Precipitation reaction) A reaction between antibody and soluble antigen resulting in visible antibody-antigen complexes. Interaction of a soluble antibody with a soluble antigen to form an insoluble complex. –observed in vitro are good serological (antigen antibody reactions in vitro). Can be used also in agar gels. Pg 789 Agglutination -is a visible clumping of a particulate antigen when mixed with antibodies specific for the particulate antigens. In vivo reaction Antibody proteins water soluble all antibodies soluble. Antigen= particulate. Connect phagocytic cells together in clumps using the antibodies

Direct agglutinations - results when soluble antibody causes clumping due to interaction with an antigen that is an integral part of the surface of a cell or other insoluble particle. Passive agglutination -is the agglutination of soluble antigens or antibodies that have been adsorbed or chemically coupled to cells or insoluble particles such as latex beads or charcoal particles. Morbidity - Incidence and prevalence of disease in a population, including both fatal and nonfatal cases. Mortality - Incidence and prevalence of death in a population. Endemic
