Document Summary
31 october 2018: vector, types, blood-feeding arthropods, vector competence, vector capacity. Cyclopropagative pathogen undergoes development and multiplication: introduction. Any agent that actively transmits a disease-producing organism ~ commonly arthropods: distinguish between mechanical and biological vectors. Mechanical pathogen undergoes no development or multiplcaito in or on the vector. Biological develops and or multiplies on or in the vector parasite has undergone a change: distinguish between the different types of biological vectors, give examples of blood-feeding arthropods and the diseases they transmit. Penetrate into the hemocoel (reproduce and or develop) and migrate to the mouth parts (salivary glands of the vector to be transmitted to the next host: define vector competence. Ability of a particular vector to become infected with a specific pathogen and also transmit the pathogen. Within the lab: an uninfected potential vector feeds on an infected animal: define vector capacity. Regular feeding on that host, life span, abundance, good dispersal ability. Perfect vector = high competence and high capacity.
