 Question 384657: what is transmission of vector?Answer by mtmorro(23)   (Show Source): You can put this solution on YOUR website!A Vector is an airborne illness which can be injected or thru skin, thru the respiratory system or blood contact most of the time with parasites or insects like mosquitos. This is not a pleasant experience it is actually in isolated cases types of biological/ chemical warfare. Transferred Parasites which reside within the blood or internal organs of the host have logistical problems in terms of infecting a new host. In contrast to fecal-oral transmission, where infective stages are excreted into the environment, potential new hosts would not normally come into contact with the parasite. (In evolutionary terms, transmission by blood transfusion would be a very recent event.) Predator-prey transmission is one strategy used by protozoa such as Toxoplasma and Sarcocystis to overcome these transmission barriers. As the name implies, predator-prey transmission involves two distinct hosts. The predator acquires the infection by eating an infected prey. This will induce an intestinal infection in the predator and result in the excretion of infective stages in the feces. The prey, generally an herbivore, will become infected by eating the infective stages it encounters in the environment. Following ingestion by an appropriate prey the parasite will cross the intestinal epithelium and infect internal organs or tissues within the host, where it waits for the next predator to ingest its prey. Here are few insects or mits whatever on might want to call them.
