autoinoculation
Autoinoculation is derived from the Latin root words "autos" and "inoculate" that mean "self implanting" or "self infection" or "implanting something from oneself".〔http://en.wiktionary.org/wiki/auto#Etymology〕〔http://en.wiktionary.org/wiki/inoculate#Etymology〕 Autoinoculation can refer to both beneficial medical procedures (e.g. vaccination) as well as non-beneficial or harmful natural processes (e.g. infection or disease). One beneficial autoinoculation medical procedure is when cells are removed from a person's body, medically altered then reinserted ("implanted" or "infected") into the same organism or person again to achieve some diagnostic or treatment aim.〔(US National Library of Medicine ). URL last accessed August 27, 2011.〕 For example stem cell treatments involve the harvesting of stem cells from one's own bone marrow and reintroduction (autoinoculation) of those cells at a later date, sometimes after altering those stem cells. Autoinoculation can also refer to the process by which viruses reproduce themselves within an organism by implanting themselves in an organism's cells, altering the metabolism, DNA repair, and replication processes of those cells, using those processes to reproduce and transmit itself throughout the organism. For example warts and Molluscum contagiosum can be spread by this method if wart tissue cells (skin cells altered by a papillomavirus) are mechanically transported to another part of the body.〔(American Family Physician )〕 This transmission or autoinoculation of the wart can occur by mechanical touching of one part of the organism to another, friction that removes a portion of the infected cells to an external surface (or another organism) and then reintroduces those cells upon contact with the body elsewhere, or when wart cells or tissue are transported though the blood stream of an organism.
