  Vector - Wikipedia, the free encyclopedia
Vector (spatial): In physics and engineering, vector most often refers specifically to an object that has a special relationship to the spatial coordinates/directions, that is, an element of a tangent bundle.
In physics vector (field) theory refers to a quantum field theory in which both chiralities of a Dirac field are present.
A biological vector is a mechanism that transmits genes or organisms.

 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.

 Nat' Academies Press, Malaria: Obstacles and Opportunities (1991)
In the case of malaria, the vector is the anopheline mosquito and the disease-causing organism is the malaria parasite.
Usually, the vector status of populations is defined by determining sporozoite and oocyst rates (the proportion of infective mosquitoes in a vector population and the proportion of mosquitoes with oocysts, respectively).
Vector Incrimination The identification of anopheline mosquitoes responsible for malaria transmission is known as vector incrimination, and the approach is the same for any given area.

 The Arboviruses: Epidemiology and Ecology
For this reason, whenever the blood-feeding activity of an arbovirus vector is interrupted for longer than the sum of the host's incubation period and the duration of viremia, the virus effectively ceases to exist in the host, and its survival is entirely dependent on the fortunes of the vector.
The simplest form of vector borne transmission involves the direct transfer of pathogen from one host to another, without replication in the vector.
The result is that vector biologists almost invariably initiate intensive studies when epidemics are already history, and we know far more about the age structure, vectorial capacity, behavior, and dynamics of vector populations after epidemics than in the crucial periods when they begin.

 Vector definition - Medical Dictionary definitions of popular medical terms
Vector: In medicine, a vector is a carrier.
For example, in malaria a mosquito serves as the vector that carries and transfers the infectious agent (Plasmodium), injecting it with a bite.
In molecular biology, a vector may be a virus (or a plasmid); a piece of foreign DNA is inserted in the vector genome to be carried and introduced into a recipient (host) cell.

Resistance of parasites to drugs, resistance of arthropods to insecticides, and the present unavailability of vaccines to many of the vector-borne diseases all underscore the importance of searching for alternative means of control.
A principal aim of the course is to incorporate cutting-edge molecular biology and genetic approaches into this research area, in order to develop new and efficacious strategies for the control of vectors and vector-borne diseases.
About half of the course will be dedicated to the study of vectors in general, with emphasis on recent discoveries.

 Dr. Jesus Valenzuela's leishmania vaccine research laboratory
The Vector Molecular Biology Unit focuses on the molecular aspects of salivary and midgut genes in vector/parasite interaction.
This novel approach to use vector salivary proteins or genes to block parasite infection may be applicable to other species of leishmania and also to other systems like in ixodid ticks to control Lyme disease.
The lipophosphoglycan (LPG) structure present in the surface of the leishmania parasite is important for the attachment of the parasite to the sand fly midgut.
