The heartworm is a type of filarial worm, a small thread- like worm, that causes filariasis. The definitive host is the dog, but it can also infect cats, wolves, coyotes, jackals, foxes, and other animals, such as ferrets, bears, sea lions and even, under very rare circumstances, humans. The parasite is commonly called "heartworm"; however, adults often reside in the pulmonary arterial system (lung arteries), as well as the heart, and a major effect on the health for the animal is a manifestation of damage to the lung vessels and tissues. Occasionally, adult heartworms migrate to the right heart and even the great veins in heavy infections. Heartworm infection may result in serious disease for the host, with death typically as the result of congestive heart failure. DistributionAlthough at one time confined to the southern United States, heartworm has now spread to nearly all locations where its vector, the mosquito, is found. Transmission of the parasite occurs in all of the United States (cases have even been reported in Alaska), and the warmer regions of Canada. The highest infection rates are found within 1. Texas to New Jersey, and along the Mississippi River and its major tributaries. It has also been found in South America, southern Europe,Southeast Asia, the Middle East,Australia, Korea, and Japan.Course of infectionHeartworms go throughout several life stages before they become adults infecting the pulmonary artery of the host animal.

The worms require the mosquito as an intermediate stage to complete their lifecycles. The rate of development in the mosquito is temperature- dependent, requiring about two weeks of temperature at or above 2. C (8. 0°F). Below a threshold temperature of 1. C (5. 7°F), development cannot occur, and the cycle is halted.[1. As a result, transmission is limited to warm weather, and duration of the transmission season varies geographically. The period between the initial infection when the dog is bitten by a mosquito and the maturation of the worms into adults living in the heart takes six to seven months in dogs and is known as the "prepatent period".
Dirofilaria immitis, the heartworm or dog heartworm, is a parasitic roundworm that is spread from host to host through the bites of mosquitoes. The heartworm is a.
After infection, the third- stage larval heartworms (L3) deposited by the mosquito grow for a week or two and molt to the fourth larval stage (L4) under the skin at the site of the mosquito bite. Then, they migrate to the muscles of the chest and abdomen, and 4. L5, immature adult). Between 7. 5 and 1. Over the next three to four months, they increase greatly in size. The female adult worm is about 3.

Asthma Program Quick facts – Asthma in Minnesota How common is asthma in Minnesota? One in 16 children (6.4%) and one in 13 adults (7.4%) currently have asthma.
By seven months after infection, the adult worms have mated and the females begin giving birth to live young, called microfilariae. The microfilariae circulate in the bloodstream for as long as two years, waiting for the next stage in their lifecycles in the gut of a bloodsucking mosquito. When ingested by a mosquito, the microfilariae undergo a series of molts to the infective third larval stage, and then migrate to the salivary glands of the mosquito, where they wait to infect another host.

The incubation period required to reach the stage where the microfilariae become transmittable to another host can be as little as two weeks or as long as six weeks, depending on the warmth of the climate, and the larval lifecycle ceases entirely if the ambient temperature drops below 1. C (5. 7°F). Hosts of Dirofilaria immitis include: Clinical signs of infectionDogs show no indication of heartworm infection during the six- month prepatent period prior to the worms' maturation, and current diagnostic tests for the presence of microfilariae or antigens cannot detect prepatent infections. Rarely, migrating heartworm larvae get "lost" and end up in unusual sites, such as the eye, brain, or an artery in the leg, which results in unusual symptoms such as blindness, seizures, and lameness, but normally, until the larvae mature and congregate inside the heart, they produce no symptoms or signs of illness. Many dogs show little or no sign of infection even after the worms become adults. These animals usually have only a light infection and live a fairly sedentary lifestyle. However, active dogs and those with heavier infections may show the classic signs of heartworm disease. Early signs include a cough, especially on exercise and early exhaustion upon exercise.
In the most advanced cases where many adult worms have built up in the heart without treatment, signs progress to severe weight loss, fainting, coughing up blood, and finally, congestive heart failure. Role of WolbachiaWolbachia pipientis is an intracellular bacterium that is an endosymbiont of D. Adults With Cognitive Impairment. All heartworms are thought to be infected with Wolbachia to some degree.
