It's not a symbiotic relationship0 - it's parasitic. The mosquito bites people to drink their blood !
not all mosquitoes carry diseases. But if they drink a diseased persons blood they can easily pass on the disease by passing on the blood to another.
Malaria
by mosquitoes or careless blood transmission
If the mosquitoes were gone then the predator of the mosquitoes wouldn't really have anything to eat.
Parasitic organisms are those that live at the expense of other organisms. Often, parasites feed on other animals. For example, mosquitos are parasites because they feed on the blood of other living things. Mosquitoes sometimes carry parasitic microorganisms too, like plasmodium falciparum, which is the protozoan that causes malaria.
Mosquitoes drink whatever blood they find.
Malaria is transmitted by the bite of an infected female Anopheles mosquito. This bite introduces the parasites from the mosquito's saliva into a person's blood. The parasites then travel to the liver where they mature and reproduce.
Mosquitoes mainly feed on blood.
Mosquitoes and flies do not deliberately spread the diseases. That is the destiny of the mosquitoes to suck your blood and habit of the flies to transmit the germs. But nothing stops you from defending yourself from their menace. Self defence is your right and duty also. But then you do it without any prejudice.
Dirofilaria immitis is a parasitic roundworm that infects dogs and other mammals' hearts and blood vessels, causing a disease known as heartworm disease. It is transmitted through the bite of infected mosquitoes and can be life-threatening if left untreated. Prevention through regular medication is important to protect pets from this parasite.
No, it would have to be a parasitic, blood sucking bug that has fed on another animal with a disease that affects the liver like hepatitis or Lyme disease
