Summary
Human diphyllobothriasis, a tapeworm infection, may increase due to sushi popularity. A case study shows a boy treated successfully with praziquantel, highlighting early diagnosis for prevention.
Area of Science:
- Parasitology
- Infectious Diseases
- Public Health
Background:
- Rising global popularity of Japanese cuisine, particularly sushi containing raw fish, presents a potential increase in human diphyllobothriasis incidence.
- Diphyllobothriasis is a parasitic infection caused by tapeworms, often transmitted through the consumption of raw or undercooked fish.
Observation:
- A case report details a 10-year-old boy who contracted diphyllobothriasis from consuming sushi.
- The patient was asymptomatic and had no other significant health issues prior to diagnosis.
Findings:
- The infection was successfully treated with a single 10 mg/kg dose of praziquantel.
- In Japan, the parasite is colloquially known as "Sanada-mushi" due to its resemblance to a Sanada cord.
Implications:
- Prompt recognition of diphyllobothriasis, potentially aided by the "Sanada-mushi" visual association, can lead to earlier diagnosis and treatment.
- Increased public awareness regarding the risks associated with consuming raw fish in sushi is crucial for preventing diphyllobothriasis.
- This case underscores the importance of considering parasitic infections in individuals consuming raw fish, even in asymptomatic patients.

01:30Leishmaniasis
Leishmaniasis is a protozoal disease caused by species of the genus Leishmania and transmitted through the bite of infected female sandflies. The parasite exists in two principal morphological forms during its life cycle. A sandfly acquires intracellular amastigotes from an infected reservoir host, such as a dog. Within the sandfly, these forms differentiate into motile, flagellated promastigotes. During a subsequent blood meal, promastigotes are injected into the human host, where they...
01:28Toxoplasmosis
Toxoplasmosis, a zoonotic disease caused by the protozoan Toxoplasma gondii, poses significant public health challenges globally due to its high seroprevalence and varied clinical manifestations. As an obligate intracellular parasite, T. gondii can infect all warm-blooded vertebrates, but felids are its only definitive hosts, shedding unsporulated oocysts into the environment. Humans typically acquire the infection through ingestion of tissue cysts in undercooked meat or oocysts from...
01:22American Trypanosomiasis
Chagas disease, or American trypanosomiasis, is a vector-borne parasitic infection caused by Trypanosoma cruzi, a flagellated protozoan (kinetoplastid) of the family Trypanosomatidae. The disease is endemic in Latin America, although cases are increasingly reported worldwide due to human migration. Transmission most commonly occurs when feces of infected triatomine bugs contaminate bite wounds or mucosal surfaces; additional routes include congenital, transfusional, transplant-related, and oral...
01:12Giardiasis
Giardiasis is a globally prevalent intestinal infection caused by the protozoan parasite Giardia duodenalis (also known as G. lamblia or G. intestinalis). This flagellated protozoan is the most frequently identified intestinal parasite in the United States and worldwide. Transmission primarily occurs via the fecal-oral route, with infection arising from ingestion of water or food contaminated with cysts. Individuals in low-resource settings, international travelers, outdoor enthusiasts, daycare...
01:28Amebiasis
Entamoeba histolytica, a protozoan parasite, is responsible for intestinal and extraintestinal amebiasis. Though a significant proportion of infections remain asymptomatic, approximately 50 million individuals annually are estimated to present with clinical disease, resulting in up to 100,000 deaths globally. The disease burden is disproportionately high in regions with lower socioeconomic status, such as parts of India, Africa, Mexico, and Latin America.Etiology and TransmissionThe infective...
01:18Trichomoniasis
Trichomonas vaginalis is a flagellated protozoan parasite and the causative agent of trichomoniasis, one of the most prevalent non-viral sexually transmitted infections in the United States. This extracellular parasite primarily colonizes the lower genitourinary tract in women—particularly the vagina—and in men, the urethra and prostate. Its structural and functional adaptations enable its survival, motility, and pathogenicity within the host environment.Structural Features and Host EntryT.
