How does Diphyllobothrium latum cause Anaemia?
latum infection to present with iron deficiency anemia. As the worm absorbs approximately 80% of dietary vitamin B12, prolonged D. latum infection usually causes vitamin B12 deficiency and megaloblastic anemia, which is reported to affect about 40% of cases.
What is the source of infection of Diphyllobothrium latum?
How did I get infected with Diphyllobothrium? You got infected by eating raw or undercooked fish. Examples of fish include salmon, trout, perch, walleyed pike, and other species — usually freshwater fish. Some fish such as salmon live in both fresh and salt water and can harbor Diphyllobothrium larvae.
What is the infective stage of Diphyllobothrium latum?
The procercoid larva are then released from the crustacean into the fish. The larvae continue to develop in the flesh of the fish, developing into the plerocercoid stage, which is the infective stage for humans. If humans ingest this fish, they will become infected.
Which information is true about Diphyllobothrium latum?
Diphyllobothrium latum and related species (the fish or broad tapeworm), the largest tapeworms that can infect people, can grow up to 30 feet long. While most infections are asymptomatic, complications include intestinal obstruction and gall bladder disease caused by migration of proglottids.
How is Diphyllobothrium latum transmitted to humans?
latum), which is the most common cause of diphyllobothriasis, also called the “fish tapeworm” or the “broad tapeworm,” is transmitted to humans by the ingestion of fish that harbor infectious larvae of the genus Diphyllobothrium causing a wide-ranging spectrum of disease and severity.
How do you prevent D Latum?
Cook fish at a temperature of 130°F (54.4°C) for five minutes. Freeze fish below 14°F (-10.0°C). Follow proper food safety handling, such as washing hands and avoid cross-contamination with raw fish and fruits and vegetables. Avoid contact with any animal known to be infected with a tapeworm.
What is the life cycle of Diphyllobothrium Latum?
Life Cycle. Immature eggs are passed in feces . Under appropriate conditions, the eggs mature (approximately 18 to 20 days) and yield oncospheres which develop into a coracidia . After ingestion by a suitable freshwater crustacean (the copepod first intermediate host) the coracidia develop into procercoid larvae .
How big can a Diphyllobothrium latum infection get?
Diphyllobothrium latum and related species (the fish or broad tapeworm), the largest tapeworms that can infect people, can grow up to 30 feet long. Several other Diphyllobothrium species infect humans, but less frequently. What are the signs and symptoms of Diphyllobothrium infection? Most infections are asymptomatic.
What kind of tapeworm can cause Diphyllobothrium latum in humans?
Diphyllobothrium latum Diphyllobothrium latum Huda Alislam Introduction Diphyllobothrium is a genus of tapeworm which can cause Diphyllobothriasis in humans.
What are the signs and symptoms of Diphyllobothrium infection?
Several other Diphyllobothrium species infect humans, but less frequently. What are the signs and symptoms of Diphyllobothrium infection? Most infections are asymptomatic. However symptoms can include abdominal discomfort, diarrhea, vomiting, and weight loss. Vitamin B12 deficiency leading to pernicious anemia may occur.
Which is the primary reservoir for Diphyllobothrium latum?
Freshwater fish serve as the primary epidemiological reservoir for D. latum, while other Diphyllobothrium species originate from marine fishes. [1] [3] Thus, the fundamental risk factor is the consumption of raw freshwater or marine fish with human disease occurring after maturation of larval stages of the tapeworm in the hosts’ intestine.
