:Infection (Babylon 5) ''is also the title of an episode of the television series Babylon 5'' An infection is the detrimental colonization of a host organism by a foreign species. An infection is, in effect, a war in which the infecting organism seeks to utilize the host's resources in order to multiply at the expense of the host. The infecting organism, or pathogen, interferes with the normal functioning and perhaps the survival of the host. Colloquially, a pathogen is usually considered a microscopic organism though the definition is broader, including Bacterium, Parasite, Fungus, Virus, Prion, and Viroid. The branch of medicine that focuses on infections and pathogens is Infectious Disease. All multicellular organisms are colonized to some degree by extrinsic organisms, and the vast majority of these exist in either a symbiosis or commensal relationship with the host. An example of the former would be the anaerobic bacterium species which colonize the mammal colon (anatomy), an example of the latter would be the various species of staphylococcus which exist on human skin. Neither of these colonizations would be considered infections. The difference between an infection and a colonization is often only a matter of circumstance. Organisms which are normally non-pathogenic can become pathogenic under the right conditions, and even the most virulent organism requires certain circumstances to cause a compromising infection. The variables involved in the outcome of a host becoming inoculated by a pathogen and the ultimate outcome include: * the route of entry of the pathogen and the access to host regions that it gains * the intrinsic virulence of the particular organism * the quantity or load of the initial inoculant * the immune system status of the host being colonized As an example, the staphylococcus species present on skin remain harmless on the skin, but, when present in a normally sterility space, such as in the capsule of a joint or the peritoneum, will multiply without resistance and create a wiktionary:huge burden on the host. ==See also== * List of infectious diseases * Infectious diseases Infectious diseases
==Wiktionary== I've put up an entry in Wiktionary, Wiktionary:Infection that contains only a link-box leading to this article (the meaning of this template is completely different between the Wiktionary and Wikipedia name spaces). That is definitely not a good way to fill Wiktionary, but will suffice for now.
