A classic example is the anopheles mosquito which acts as a vector for the disease malaria by transmitting the malarial parasite plasmodium to humans. In this case plasmodium is harmless to the mosquito (its intermediate host) but causes the disease malaria in humans (its definitive host).
There are two types of vector that convey infectious organisms to a host: mechanical and biological. Microbes do not multiply within mechanical vectors - mechanical vectors only physically transport microbes from host to host. In contrast, microbes must propagate within a biological vector before the biological vector can transmit the microbes.
