Heartworm or scientifically called, Dirofilaria immitis, is a parasitic worm that is spread between animals through mosquitoe bites. Heartworm is spread by mosquitos. A mosquito bites an infected animal and when that mosquito bites a second animal, the tiny heartworm larvae are injected into the animals skin and the larvae develop in the animal’s tissues. The heartworm typically reside in the heart and lungs of an infected animal and seriously affect the host animal by causing damage to the animals tissue which leads to infection and sometimes death.
