Question

Quizplus · Accepted Answer

Animals that participate in the life cycles of pathogens and transmit pathogens from host to host are called biological vectors. Biological vectors are living organisms that can transmit infectious agents to humans or other animals. These vectors become infected with the pathogen either by feeding on an infected host (as in the case of mosquitoes that transmit malaria) or by becoming infected during their life cycle (as in the case of ticks that transmit Lyme disease). Once the biological vector is infected, it can then transmit the pathogen to a new host, either directly through its bite or indirectly by contaminating food or water.
