vector (redirected from Vectorise)

vector /vec·tor/ (vek´ter)

1. a carrier, especially the animal (usually an arthropod) that transfers an infective agent from one host to another.

2. a plasmid or viral chromosome into whose genome a fragment of foreign DNA is inserted; used to introduce foreign DNA into a host cell in the cloning of DNA.

3. a quantity possessing magnitude, direction, and sense (positivity or negativity).vecto´rial

biological vector  an arthropod vector in whose body the infecting organism develops or multiplies before becoming infective to the recipient individual.

mechanical vector  an arthropod vector which transmits an infective organism from one host to another but which is not essential to the life cycle of the parasite.

vec·tor (vktr)

n.

1. An organism, such as a mosquito or tick, that carries disease-causing microorganisms from one host to another.

2. A bacteriophage, a plasmid, or another agent that transfers genetic material from one location to another.

3. A quantity, such as velocity, completely specified by a magnitude and a direction.

Vector

An animal carrier that transfers an infectious organism from one host to another. The vector that transmits Lyme disease from wildlife to humans is the deer tick or black-legged tick.

Mentioned in: Bartonellosis, Dengue Fever, Hemorrhagic Fevers, Leishmaniasis, Lyme Disease, Rabies

[vek′tər]

Etymology: L, carrier

1 a quantity having direction and magnitude, usually depicted by a straight arrow. The length of the arrow represents magnitude, and the head represents direction.

2 a carrier, especially one that transmits disease. A biologic vector is usually an arthropod in which the infecting organism completes part of its life cycle. A mechanical vector transmits the infecting organism from one host to another but is not essential to the life cycle of the parasite. Kinds of vectors include dogs, which carry rabies; mosquitoes, which transmit malaria; and ticks, which carry Rocky Mountain spotted fever.

3 a retrovirus that has been modified by alteration of its genetic component. Through recombinant deoxyribonucleic acid techniques, genes that cause harmful effects such as cancer are removed and genes that mediate synthesis of essential enzymes are added. The vector then can be injected into a patient who suffers from an enzyme deficiency, such as Lesch-Nyhan syndrome. vector, v., vectorial, adj.

n a carrier that transmits a disease from one party to another.

vector

1. a carrier, especially the animal (usually an arthropod) which transfers an infective agent from one host to another, e.g the tsetse fly, which carries trypanosomes from animals to humans, dogs, bats and other animals that transmit the rabies virus. In molecular biology, a DNA molecule which serves to transfer DNA into a host cell.

2. a quantity possessing magnitude, direction and sense (positivity or negativity).

biological vector

an arthropod vector in whose body the infecting organism develops or multiplies before becoming infective to the recipient individual.

cloning vector

a DNA molecule used to transfer an inserted DNA segment into a host cell. Includes other viruses, phages and bacterial plasmids. Called also cloning vehicle.

mechanical vector

an arthropod vector that transmits the infective organisms from one host to another but is not essential to the life cycle of the parasite.

shuttle v's

vectors which contain both prokaryotic and eukaryotic replication signals, thus allowing replication of the vector in both kinds of cells.

targeting vector

a vector carrying a DNA sequence that is able to take part in a specified chromosomal crossover in the host.

Epidemiology 1. An 'inactive' vehicle of transport of an agent of disease; an intermediate host of parasites with indirect life cycles 2. A thing that transmits a pathogen–eg, an arthropod transporting viruses and parasites, or an inanimate intermediary in indirect transmission of an agent from a reservoir to a susceptible host; a carrier that transmits a pathogen from one host to another
