Diphyllobothriasis is a disease caused by infection with adult tapeworms of the genus Diphyllobothrium. Humans acquire the infection by consuming the raw or inadequately cooked flesh, roe, liver, or other organs of infected fish. Diphyllobothrium latum infection has not been reported in Malaysia; we are reporting the first case. The patient was a 62 year old Chinese male seen at the outpatient ...

We report on the intestinal helminth fauna of 56 South American sea lions, Otaria flavescens, and 5 South American fur seals, Arctocephalus australis, from northern Patagonia, Argentina. A total of 97,325 helminth specimens were collected from sea lions. Gravid individuals were represented by 6 species of parasites: 1 digenean (Ascocotyle (Ascocotyle) patagoniensis), 1 cestode (Diphyllobothrium...

Until 2012, a total of 48 cases of diphyllobothriasis had been reported in Korea, all of which were morphologically identified as Diphyllobothrium latum. However, some of these specimens were analyzed by nucleotide sequencing of the mitochondrial cox1 gene, which showed that all were D. nihonkaiense, not D. latum. After that, 3 further cases of diphyllobothriasis were confirmed as D. nihonkaien...

Parasites collected from free-ranging black bears, Ursus americanus Pallas, 1780, from northeastern Minnesota or northern Michigan include the dog tick, Dermacentor variabilis (Say, 1821), the winter tick, D. ALBIPICTUS (Packard, 1869), a louse, Trichodectes pinguis euarctidoes Hopkins, 1954, an ascarid worm, Baylisascaris transfuga (rudolphi, 1819), a filarial worm, Dirofilaria ursi Yamaguti, ...

Diphyllobothrium latum infection in humans is not common in Republic of Korea. We report a case of fish tapeworm infection in a 10-year-old boy after ingestion of raw perch about 8 months ago. The patient complained of recurrent abdominal pain and watery diarrhea. A tapeworm, 85 cm in length, without scolex and neck, was spontaneously discharged in the feces of the patient. The patient was trea...

Diphyllobothriasis, which is rarely described in Brazil, was reported initially as a travelers disease and as an accidental infection in individuals who ate raw freshwater fish. This report aims to present the case of a 20-year-old patient with confirmed Diphyllobothrium latum infection.

Diphyllobothrium latum and Diphyllobothrium nihonkaiense are morphologically similar to each other, and only genetic method can differentiate clearly between the 2 species. A strobila of diphyllobothriid tapeworm discharged from a 7-year-old boy was analyzed to identify the species by mitochondrial cytochrome c oxidase subunit 1 (cox1) gene sequencing. He and his family (total 4 persons) ate sl...
