Action in Mosquitoes
Mosquitoes carrying such arboviruses stay healthy because their immune systems recognizes the virions as foreign particles and "chop off" the virus's genetic coding, rendering it inert. Human infection with a mosquito-borne virus occurs when a female mosquito bites someone while its immune system is still in the process of destroying the virus's harmful coding. It is not completely known how mosquitoes handle eukaryotic parasites so they can carry them without being harmed. Data has shown that the malaria parasite Plasmodium falciparum alters the mosquito vector's feeding behavior by increasing frequency of biting in infected mosquitoes, thus increasing the chance of transmitting the parasite.

Famous quotes containing the words action and/or mosquitoes:
“Though with their high wrongs I am struck to the quick,
Yet with my nobler reason ‘gainst my fury
Do I take part. The rarer action is
In virtue than in vengeance.”
—William Shakespeare (1564–1616)
“I noticed, as I had done before, that there was a lull among the mosquitoes about midnight, and that they began again in the morning. Nature is thus merciful. But apparently they need rest as well as we.”
—Henry David Thoreau (1817–1862)
