Lung flukes are parasitic organisms called trematodes. The most common lung fluke that affects dogs in North America is called the Paragonimus kellicotti, also known as the North American lung fluke. Other species of lung flukes can infect dogs in other areas of the world but are they are rarely found in North America.

How do you get rid of dog flukes?

Treatment of Lancet Fluke in Dogs Praziquantel is commonly used both in the treatment of tapeworms and of flukes due to its ability to paralyze the parasites, inhibiting their ability to hold on to any surface areas. This allows them to be excreted through the bile and the liver.

What are the symptoms of trematode?

Symptoms can include fever, nausea, swollen liver, skin rashes and severe abdominal pain. The chronic phase begins when the worms reach the bile ducts, mature and start producing eggs. These eggs are released into the bile then reach the intestine before being evacuated in faeces.

Are trematodes contagious?

Transmission of trematodiases can occur through the consumption of water and food that is contaminated with trematodes in the larval stages of their life cycle. In a host organism, eggs of trematodes can spread through faeces, and sputum if the host is infected by a lung fluke.

How are trematodes detected?

Various antibody-based serologic tests are used in the diagnosis of most trematode infections. These tests are used for diagnosis and for seroepidemiologic studies. Commonly used tests include indirect hemagglutination, indirect immunofluorescence, and ELISA. ELISA is most sensitive and practical.

Etiology

Adult trematodes present in the lungs, alimentary system, mesenteric or portal veins.

Access to raw or undercooked fish or shellfish. Swimming in water contaminated with cercariae of Heterobilharzia Americana.

How do pulmonary trematodes affect dogs?

Infection with adult pulmonary trematodes causes lung cysts in both dogs and cats. The adult flukes are reddish-brown and oval and measure about 14 by 7 mm. 6 Eggs are golden brown and measure 75 to 118 by 42 to 67 mm. 1 The eggs are passed through the lung cyst wall, where they are coughed up, swallowed, and passed in the feces. The life cycle includes several snail species as the first intermediate host and crayfish or crabs as the second. Patients become infected via ingestion of raw crayfish or a paratenic host infected with the metacercariae. 6 The trematode penetrates the intestinal wall, and within the peritoneal cavity, the flukes can pass through the diaphragm where they enter the lungs and establish an infection.

How long does it take for a trematode to deworm?

Deworming for the trematode can include praziquantel (20-30 mg/kg PO once) and fenbendazole (50 mg/kg/day for 10-14 days ). 2,3 Aggressive IV fluid therapy, anti-nausea medications, GI protectants, and other supportive measures are needed in most patients. Treatment of the rickettsial organism usually results in a rapid improvement in clinical signs within 1 to 2 days and includes administration of a tetracycline (eg, doxycycline 5 mg/kg PO twice daily) for 1 to 2 weeks. 3,5 If vomiting and nausea are severe, parenteral administration may be necessary.

What is the fluke in dogs?

Infection with the fluke in and of itself causes only mild enteritis, but N salmincola serves as a vector for Neorickettsia helminthoeca, a rickettsial organism that causes salmon poisoning disease in dogs. 3-5 Elokomin fluke fever is another disease caused by a very similar Neorickettsia species that can be transmitted by N salmincola, producing similar but less severe signs. 2-5 Clinical disease commonly includes fever, vomiting, diarrhea, dehydration, lymphadenopathy, and thrombocytopenia. Less common findings include hematochezia, hematemesis, and central nervous system signs. 3-6 Illness usually develops within 5 to 7 days of ingesting the uncooked fish, but incubation can be as long as a month. 2-5 Mortality rates are high in the absence of supportive intravenous (IV) fluid treatment and antibiotics.

How do flukes get into a dog?

Eggs of these species are oval, light brown, and large (98-134 × 62-68 mm). 1 These flukes are acquired by dogs and cats through the ingestion of a wide variety of paratenic and intermediate hosts. The life cycle includes freshwater snails (eg, Helisoma spp) as the first intermediate host. Cercariae develop into metacercariae after penetrating the skin of tadpoles. 2 Frogs, snakes, and mice become infected by ingesting the tadpoles. Dogs and cats then become infected after ingesting the intermediate host.
