Anticorps Canine Heartworm (HW2-81): sc-65671

Heartworm is a parasitic roundworm that is spread from host to host through the bites of mosquitoes. A mosquito ingests heartworm larvae, called microfilariae, from an infected host. The mosquito then transfers the larvae to another uninfected host when next it feeds. The microfilariae then go through several changes to reach adult form, eventually traveling to the right side of the heart to reproduce. In the final reproductive stage of their life cycle, Heartworms can reach up to 12 inches in length and reside in the heart of its host where they may stay for many years, commonly killing the host. Early symptoms in dogs include a cough, especially on exercise, and early exhaustion upon exercise. More advanced cases progress to severe weight loss, fainting, coughing up blood, and, finally, congestive heart failure leading to death.
