In epidemiology, a disease vector is any living [1] agent that carries and transmits an infectious pathogen such as a parasite or microbe, to another living organism. [ 2 ] [ 3 ] Agents regarded as vectors are mostly blood-sucking insects such as mosquitoes.
The vector itself generally carries a DNA sequence that consists of an insert (in this case the transgene) and a larger sequence that serves as the "backbone" of the vector. The purpose of a vector which transfers genetic information to another cell is typically to isolate, multiply, or express the insert in the target cell.
The use of natural vector predators, such as bacterial toxins or botanical compounds, can help control vector populations. Using fish that eat mosquito larvae, the use of Catfish to eat up mosquito larvae in ponds can eradicate the mosquito population, or reducing breeding rates by introducing sterilized male tsetse flies have been shown to ...
Viral vector manufacturing methods often vary by vector, although most utilize an adherent or suspension-based system with mammalian cells. [72] For viral vector production on a smaller, laboratory setting, static cell culture systems like Petri dishes are typically used.
Vectors may be mechanical or biological. A mechanical vector picks up an infectious agent on the outside of its body and transmits it in a passive manner. An example of a mechanical vector is a housefly, which lands on cow dung, contaminating its appendages with bacteria from the feces, and then lands on food prior to consumption. The pathogen ...
How vectors work to transfer genetic material. Gene therapy utilizes the delivery of DNA into cells, which can be accomplished by several methods, summarized below. The two major classes of methods are those that use recombinant viruses (sometimes called biological nanoparticles or viral vectors) and those that use naked DNA or DNA complexes (non-viral methods).
Vector Limited, a New Zealand gas and electricity supplier; Vector Marketing, a multi-level knife marketing company; Vector Motors, an automobile manufacturer; Vector Launch, an American space technology company, 2016–2019; State Research Center of Virology and Biotechnology VECTOR, a biological research center in Russia
The 1972 Biological Weapons Convention supplements the Geneva Protocol by prohibiting the development, production, acquisition, transfer, stockpiling and use of biological weapons. [13] Having entered into force on 26 March 1975, this agreement was the first multilateral disarmament treaty to ban the production of an entire category of weapons ...
