The authors previously reported that an extract fromZingiber officinale, traditionally eaten along with raw fish and used in traditional Chinese medicine, effectively destroyedAnisakis larvae in vitro. In this study, we analyzed the effective components of ginger rhizomes. Methanol extracts were fractionated after first being treated with HCl at pH 3, then(More)
The eggs of Trichuris, detected in the feces of 19 persons who had stayed in institutions for mentally retarded and/or multi-handicapped patients, were identified as those of T. vulpis (Froelich, 1789) on the basis of morphological features. This is the first record of human infection with the canine whipworm in Japan.
A 51-year-old woman with a history of eating raw fish over a period of 2 weeks developed a progressive abdominal pain and leukocytosis with signs of small bowel obstruction. Eosinophilia was not detected in the peripheral blood. The patient underwent surgery to clarify the possibility of ileus. Partial small bowel near the ileum was trapped by a peritoneal(More)
Pelodera strongyloides is a free-living soil nematode of the order Rhabditida. We report an 18-year-old man with P strongyloides skin infestation. In this case, pruritic follicular papulopustules developed on the buttocks, then the right flank. Skin scrapings revealed many live rhabditiform larvae that were cultured adult worms and hatched ova, identified(More)
The interaction between protoscoleces of Echinococcus multilocularis and activated murine macrophages was examined in this study. Marked protoscolicidal activity was displayed by peritoneal macrophages (PM) activated with interferon-gamma (IFN-gamma), or IFN-gamma plus lipopolysaccharide. Pretreatment of the parasites with heat-inactivated specific murine(More)
A 58-year-old woman living in Shizuoka Prefecture, Japan, complained of severe epigastric pain and nausea about 8 h after having eaten 'Sashimi'. A gastrocamera examination undertaken as a result of her clinical history of gastric anisakiasis indicated that a large number of worms had penetrated the posterior walls. Fifty-six larval nematodes were directly(More)
Gnathostomiasis is rarely reported in travelers, although the disease remains a major public health problem in Southeast Asia. A creeping eruption and Quincke's edema (slowly migrating erythema with pruritus) appeared in two Japanese men who had eaten raw freshwater shrimp in Myanmar. A Gnathostoma larva was found in subcutaneous tissue from one of the men.(More)
Since the first reported case of human dirofilariasis in 1964, a total of 56 cases have been recorded from Japan, including 39 pulmonary and 16 extra-pulmonary cases. The difference in case number between pulmonary and extre-pulmonary sites is statistically highly significant (P = 0.001). Distribution of the lesion in pulmonary dirofilariasis is mainly(More)
Hepatocellular carcinoma associated with chronic Schistosoma mansoni infection in a chimpanzee, estimated to be a 12-year-old and born in West Africa, is reported. The hepatic tumor appeared as a solitary firm nodule, and histological examination revealed well-differentiated hepatocellular carcinoma with a trabecular pattern. Hepatitis B virus and hepatitis(More)
Marine fishes and squids caught in the Gulf of Tongking, the East China Sea and the Yellow Sea were dissected, and many Anisakidae larvae were found in them. The larvae of Anisakis simplex (Anisakis Type I larvae), the most important causative agent of anisakiasis, was found in about 30% of fishes and squids caught in the Gulf of Tongking and in about 60%(More)
