Dirofilaria immitis is a parasitic worm that causes heartworm disease in dogs and other animals. It is transmitted through mosquito bites, where the larvae enter the bloodstream and eventually reach the heart and lungs. The adult worms can grow up to 12 inches long and can cause severe damage to the heart and blood vessels. Heartworm disease can be fatal if left untreated, but it can be prevented through regular use of heartworm preventatives.
