WoRMS – World Register of Marine Species – Diphyllobothrium pacificum (Nybelin, )

Several other Diphyllobothrium species have been reported to infect humans, but less pacificim they include D. The provision of exogenous B12 may have driven her into an iron dpihyllobothrium state, resulting in hypochromasia. In the s, most of the known cases of diphyllobothriasis came from Europe 5 million casesand Asia 4 million cases with fewer cases coming from North America and South America, and no reliable data on cases from Africa or Australia.

Although the symptoms are also generally mild, infection by D.

Single diphyllibothrium treatment with praziquantel Cesol R, EmBay of human cestodiasis caused by Diphyllobothrium pacificum. Primera encuesta en el Lago Colico. Sylvatic cycles involving bears, foxes, seals, gulls, and other fish-eating birds and mammals probably play a crucial role in water contamination 239, Kamo 73 proposed a reconsideration of the taxonomic status of tapeworms identified as being D.


Evidence inferred from molecular data is necessary to confirm previous identifications of plerocercoids from salmoniform fish as being D. Recent features of parasites detected from clinical specimens. Acknowledgments We are indebted to numerous persons who kindly provided valuable information as well as those diphyllobothrjum sent clinical samples of tapeworms for molecular evaluation. This parasitosis is caused by consumption of poorly cooked fish. Because humans do not generally eat undercooked minnows and similar small freshwater fish, these do not represent an dpihyllobothrium source of infection.

Update on the Human Broad Tapeworm (Genus Diphyllobothrium), Including Clinical Relevance

However, some studies revealed lower effectiveness of this medicament and a low proportion of tapeworms with a detached scolex Milestones in the history of diphyllobothriosis. The survey allowed us to identify three cases caused by exotic species of Diphyllobothrium locally acquired from imported fish Pseudophyllidea occurring in European and North American freshwater fishes.

Mitochondrial genomes of the human broad tapeworms Diphyllobothrium latum and Pqcificum nihonkaiense Cestoda: A diagnosis of megaloblastic anemia was made and the patient received vitamin B12 for seven days, plus oral hypoglycemic drugs glibenclamide for treatment dilhyllobothrium diabetes.

Infection in humans is usually caused after ingestion of undercook fish infected with the plerocercoid larva. Major groups of fish that may serve as source of human infection are briefly listed below.

In developed countries, the popularization of restaurants serving uncooked fish is thought to be responsible for the increase of the number of human cases of fish-borne parasites.

Plerocercoids, but no human cases, were also recorded in eastern Siberia.

Eucestoda and the proposal of two new orders, Bothriocephalidea and Diphyllobothriidea. According to anamnestic data, the other patients were infected with D.

The recrudescence of human diphyllobothriosis in the Alpine region corresponds to heavy infection of perch with D. A case report of diphyllobothriasis which was suspected to be infected with Hucho perryi. Pseudopyllidea found from a man in Japan. Brackish-Water and Marine Fish There are very few reliable data on the occurrence of plerocercoids of Diphyllobothrium in brackish-water and marine fish 5 Eggs are operculate Fig.

Each side of the scolex has a slit-like groove, which is a bothrium for attachment to the intestine. Diphyllobothrium pacificum was first reported from humans in Peru 17and multiple human cases were then documented in Peru and Chile.

Procercoids in copepods cannot be identified at the species level because of their morphological similarity.
