Parasites

  • Heartworm disease is a serious and potentially fatal disease. It is caused by a blood-borne parasite known as Dirofilaria immitis. Adult heartworms may live up to five years and, during this time, the female produces millions of offspring called microfilaria. You can prevent your dog from getting heartworms by using a heartworm preventive.

  • Heartworm disease or dirofilariasis is a serious and potentially fatal disease. It is caused by a blood-borne parasite known as Dirofilaria immitis. Treatment usually consists of several parts including an injectable drug to kill adult heartworms, antibiotics, and treatment to kill microfilaria. There is some risk involved in treating dogs with heartworms, although fatalities are rare.

  • Hookworms are intestinal parasites of the cat and dog. Their name is derived from the hook-like mouthparts they use to anchor themselves to the lining of the intestinal wall. In general, cats tend to harbor relatively few hookworms when compared to the large numbers found in dogs.

  • Hookworms are intestinal parasites of the cat and dog that get their name from the hook-like mouthparts they use to anchor themselves to the lining of the intestinal wall. A large number of hookworms can cause inflammation in the dog's intestine as well as a life-threatening decrease in the number of red bloods cells, which is called anemia. This problem is most common in puppies, but can occur in adult dogs.

  • This handout is designed to give you an overview of some of the internal parasites that can infect your dog. Intestinal worms can be a serious problem in young puppies. Heartworm disease is a major life-threatening problem in dogs. Speak to your veterinarian about the most appropriate parasite control program for your dog.

  • Knemidocoptes is a type of bird mite that typically effects canaries, cockatiels and parakeets. It is commonly referred to as scaly face and leg disease. Specific antiparasitic drugs will be prescribed by a veterinarian to treat this disease.

  • Leishmaniasis is a serious condition spread by flies that can affect dogs, cats, and people. It can severely damage the internal organs or skin and even with treatment, the outcome is often not successful.

  • Lung flukes in North America are parasites called Paragonimus kellicotti that infect the lungs of cats after they have eaten an infected crayfish or rodents that have eaten infected crayfish. Eggs are then released by the parasite into the cat’s sputum to be coughed out or swallowed and released in the feces to continue the life cycle. Lung flukes can be found anywhere in North America but more commonly around the Mississippi River and Great Lakes. Infected cats can be symptom-free or may develop cough with sometimes bloody mucus, pneumonia, pneumothorax, lethargy and weakness. Diagnosis can include locating eggs of the parasite from feces or mucus from the lungs. X-rays can also reveal cysts in the lungs caused by the parasite. Treatment requires one of 2 commonly used anti-parasitic medications: Praziquantel or Fenbendazole. Although zoonotic, these parasites won’t transmit directly from cats to humans.

  • There are many species of lungworm that can cause respiratory problems in dogs. Infection is acquired through either: ingestion of an intermediate host such as snails or slugs, ingestion of animals that have been infected by eating these animals or depending on the species, from an infected dog by contact with saliva, nasal discharge, or contaminated food and water bowls. Lungworms can be found throughout North America and the world with certain species seen in certain areas. Clincal signs can range from asymptomatic to tachypnea, coughing, sneezing, wheezing, respiratory distress or exercise intolerance. The degree of clinical signs is usually proportional to the strength of the dog’s immune system. Diagnosis involves history, physical exam, x-rays and organism identification through either baermann fecal examination or BAL/bronchoscopy. Treatment involves use of specific antiparasitic drugs for various lengths of time depending on type and severity of infection. Prognosis is good but re-infection can occur.
