The larvae then molt a final time and migrate to the pulmonary artery, where they begin to mate and
release microfilaria of their own.
It can occur if mostly male heartworms are causing an infection, since they do not
release microfilaria.
Tiny heartworm larvae are injected into the blood stream where they mature over the span of about 6 months until they reach adulthood in the veins of the pulmonary artery and lungs, where they reproduce and
release microfilaria into the blood for the mosquito to ingest and pass on.
Two are the others canine filariases
releasing microfilariae in the blood and described in Italy: Dirofilaria (Nochtiella) repens and Acanthocheilonema (syn.: Dipetalonema) reconditum (Pampiglione et al., 1995; Tarello, 1999).
Adult worms reside in the subcutaneous tissues of infested animals and
release microfilariae that circulate in the blood (Tarello, 1999).
Not exact matches
If a dog is bitten by the pregnant female mosquito, her
microfilariae are
released into the circulatory system and they wait there for a new mosquito to bite the dog again.
As the worms mature and mate, they produce
microfilaria that are
released into the blood stream, picked up by mosquitoes, and spread to other unsuspecting hosts.
Mature female heartworms
release offspring, called
microfilaria, into the blood stream.
Adult heartworms can then produce live
microfilaria, which are
released into the bloodstream and the cycle repeats when another mosquito comes along.
Once in the dog's bloodstream, the larvae mature through several stages and eventually take up residence in the heart, from which they
release offspring called
microfilaria into the bloodstream of the dog.
These reactions are presumably caused by
release of protein from dead or dying
microfilariae.
The immune system can destroy the
microfilaria released by adult heartworms in the pulmonary capillaries, resulting in a negative heartworm test.
In an affected dog or cat, female heartworms that reside in the pulmonary artery
release small larval forms called
microfilaria.
The Life Cycle First, adult female heartworms
release their young, called
microfilaria, into an animal's bloodstream.
These
microfilaria are
released into the bloodstream, where a biting mosquito can pick them up and perpetuate the cycle as it transfers the
microfilaria to another host.
Mature heartworms
release larvae, known as
microfilaria, into the bloodstream.
Once the parasites mature (about six months from the time they enter the dog's body), they begin to
release immature heartworms, known as
microfilaria.
When a dog or other suitable host has a mature heartworm infection, female worms
release their young (
microfilariae) directly into the animal's bloodstream.
Adult heartworms reproduce and
release the next generation of immature larval worms, called
microfilaria, into the bloodstream.
