	Vector (biology) - Wikipedia, the free encyclopedia
		Species of mosquito, for example, serve as vectors for the disease-causing West Nile Virus; which the insects may ingest by feeding from an infected bird and regurgitate into a human, infecting him or her.
		This sense of "biological vector" is the primary one in epidemiology and in common speech.
		A vector in this sense is a DNA construct, such as a plasmid or a bacterial artificial chromosome, that contains an origin of replication.

	Hepatitis A
		A fly may act as a mechanical vector of diseases such as Hepatitis A, which means the fly carries the infective organism on its feet or mouth parts and contaminates food or water which a person then consumes.
		A biological vector actually develops an infective organism in its body and passes it along to its host, usually through its saliva.
		A fly can be a biological vector, as in the transmission of leishmaniasis by the sandfly.

	Routes of transmission of infectious diseases agents
		The term vector is sometimes used in a broad sense to signify anything that allows the transport and/or transmission of a pathogen.
		The disease agent and the biological vector are considered to have a long-standing ecological relationship.
		Biological vectors are usually persistently infected with the disease agent and may even be a required part of that organism’s life cycle.

	Biological vector
		In biology, a vector is a means to transmit genetic information or whole organisms (usually pathogens) between other organisms.
		Viruses, for example, are considered as vectors because they spread by introducing their genetic information into their hosts.
		Vectors are becoming more common and powerful tools of research as the human genome and genomes of other organisms are being extensivly studied.

	Transmission dynamics within biological vector populations (Site not responding. Last check: 2007-10-10)
		Different forms of transmission also occur within biological vector populations and can be very important in maintaining a source of infection to veterinary species.
		Transovarial transmission is a form of vertical transmission in which the female vector passes the infectious agent through her eggs to the next generation.
		This continuance was attributed to the movement of infected animals and the exposure of uninfected animals to contaminated objects, however, transovarial transmission may have contributed to the overwintering ability of the virus.

	Biological Management of Possums - Measuring the Spread of the Candidate Possum Biocontrol Vector Parastrongyloides ...
		The NSSC has accorded a high priority to research aimed at biological control of possums, acknowledging this to be the only cost-effective, long-term way to achieve a sustained reduction in possum numbers.
		The identification of a possum-specific agent, such as a parasite, that could be used as a potential vector for DNA coding for genes to effect biological control was given high priority (Atkinson and Wright, 1993).
		Additionally the parasite is particularly suited as a biological control vector because it can achieve prevalences of >90 percent., and transmits from possum to possum naturally.

		Biological control methods are not widely used and are primarily experimental.
		One option in which biological control is often used, however, is the placement of small fish that eat mosquito larvae in certain containers, such as decorative fountains or 55-gallon drums.
		Since chemical control is generally restricted to containers that cannot otherwise be eliminated or managed, and biological control is still largely experimental, environmental methods are likely to be the most effective for long-term control of Aedes aegypti.

	Arthropod Vectors of Biological Agents and Their Control
		In the event of such an attack, control of the vector is a key component to limiting its effects.
		When an attack with a vector-dependent agent is suspected the vector must be rapidly identified to confirm the identity of the agent and to guide and monitor efforts at control.
		If the vector and disease should become established, which can be a risk if the vector is well matched to the area, then a number of long term measures, such as diverting or re-engineering the flow of rivers may become necessary.
