What is vector and host?

What is a vector and reservoir host?

A disease reservoir is analogous to a water reservoir. But instead of supplying water, a disease reservoir serves as a supply for a virus or other pathogen. Vector: Any living creature that can pass an infection to another living creature.

What is a vector in infection control?

A vector is a living organism that transmits an infectious agent from an infected animal to a human or another animal.

What is a vector in terms of a virus?

Viral vectors are tools designed to deliver genetic material into cells. Viruses have evolved to develop specialized mechanisms which transport their genomes inside the cells they infect.

What are vectors Class 9?

What is host and vector in microbiology?

Vector transmission occurs when a living organism carries an infectious agent on its body (mechanical) or as an infection host itself (biological), to a new host. Vehicle transmission occurs when a substance, such as soil, water, or air, carries an infectious agent to a new host.

What is called vector give one example in biology class 9?

Traditionally in medicine, a vector is an organism that does not cause disease itself but which spreads infection by conveying pathogens from one host to another. Species of mosquito, for example, serve as vectors for the deadly disease Malaria.
