pathogenicity ability of an agent to produce disease-success depends on its speed of reproduction, extent of tissue damage, and production of toxins
toxigenicity factor important in determining a pathogen's virulence, such as production of soluble toxins or endotoxin
immunogeniciy ability of pathogens to induce immune response
virulence protency of a pathogen measured in terms of number of microorganisms or micrograms of toxin required to kill a host
spread of infection site of entry, route of entry, mechanism of infection
site of entry skin and mucous membrane; alimentary,genitourinary and respiratory tracts; eyes and ears
route of entry direct contact, inhalation, ingestion, vector bite
mechanism of infection adhesins, enzyme release, phagocytic escap, acid resistance
bacteria can be aerobic or anaerobic and motile or immotile
cocci spherical shaped
bacilli rod like forms
spirochetes spiral forms
septicemia the presence of bacteria in the blood and is caused by a failure of the body's defences, can travel through body and cause shock
virus microorganism consisting of a nucleic acid protected from the environment by layers of proteins, cannot survive long outside of a cell and have no metabolism
virus disease most common affliction of humans, transfer from organism to organism, trasmit through droplets, direct contact, blood, airborn, sexual-body fluid
fungal disease large microorganism with thick walls, grow as single-celled yeasts (spheres) or multi-celled molds (filaments of hyphae), present on skin
