“…One patient in Chile was most probably infected after eating smoked "jurel" (Trachurus murphyi (Wicht et al, unpublished). An outbreak of diphyllobothriosis in Geneva has recently been reported by Jackson et al (67). In some countries previously considered to be disease free (Austria, Czech Republic, Belgium, The Netherlands, and Spain), sporadic cases have been reported over the last 6 years, which were presumably linked to the consumption of raw imported fish (Wicht et al, unpublished).…”

SUMMARYTapeworms (Cestoda) continue to be an important cause of morbidity in humans worldwide. Diphyllobothriosis, a human disease caused by tapeworms of the genusDiphyllobothrium, is the most important fish-borne zoonosis caused by a cestode parasite. Up to 20 million humans are estimated to be infected worldwide. Besides humans, definitive hosts ofDiphyllobothriuminclude piscivorous birds and mammals, which represent a significant zoonotic reservoir. The second intermediate hosts include both freshwater and marine fish, especially anadromous species such as salmonids. The zoonosis occurs most commonly in countries where the consumption of raw or marinated fish is a frequent practice. Due to the increasing popularity of dishes utilizing uncooked fish, numerous cases of human infections have appeared recently, even in the most developed countries. As many as 14 valid species ofDiphyllobothriumcan cause human diphyllobothriosis, withD. latumandD. nihonkaiensebeing the most important pathogens. In this paper, all taxa from humans reported are reviewed, with brief information on their life history and their current distribution. Data on diagnostics, epidemiology, clinical relevance, and control of the disease are also summarized. The importance of reliable identification of human-infecting species with molecular tools (sequences of mitochondrial genes) as well as the necessity of epidemiological studies aimed at determining the sources of infections are pointed out.

“…In light of recent case reports, human infections with exotic (imported) species of Diphyllobothrium might be present in a number of countries, being actually underestimated. Imported parasites may also enhance the probability of the appearance of outbreaks even in countries with a high level of medical care (39,67 …”

“…Clinical symptoms are light diarrhea and abdominal discomfort, and, in the case of D. latum infection, vitamin-B12-deficienct anemia. Human diphyllobothriasis has been reported in Europe (Dick et al 2001;DupouyCamet and Peduzzi 2004;Chai et al 2005;Jackson et al 2007), Asia (Dick et al 2001;Yamane and Shiwaku 2003;Chai et al 2005), North America (Dick et al 2001;Chai et al 2005), and South America (Torres et al 1993;Santos and de Faro 2005;Sampaio et al 2005). Diphyllobothriasis due to D. nihonkaiense was previously restricted to Asia, particularly Japan (Yamane et al 1986;Yoshida et al 1999;Ando et al 2001;Yamane and Shiwaku 2003;) and Korea (Kim et al 2007); however, the D. nihonkaiense infections have recently been reported in France (Yera et al 2006), Switzerland (Wicht et al 2007;Shimizu et al 2008), and Canada (Wicht et al 2008).…”

Global increases in salmon consumption and changes in fish-eating habits have meant that Diphyllobothrium infections now occur in regions where they were previously absent. In the present paper, a case of diphyllobothriasis through the likely ingestion of raw salmon in New Zealand in a Japanese patient is reported. The causative tapeworm species was identified as Diphyllobothrium nihonkaiense based on mitochondrial DNA analysis of proglottid expelled from the patient.

“…Occasionally, Diphyllobothrium latum infection can cause malignant anemia due to the consumption of vitamin B12 by the tapeworm. Several outbreaks caused by Diphyllobothrium had a significant impact on economy and public health [ 2 , 3 ].…”

“…To date, about 18 species of Diphyllobothrium have been reported to infect humans, with D. latum and Diphyllobothrium nihonkaiense being the most common [ 4 ]. Human diphyllobothriasis has been reported in Europe [ 3 , 5 - 7 ], North America [ 8 , 9 ], South America [ 2 , 10 , 11 ], and Asia [ 12 - 15 ]. In mainland China, a total of 20 human cases have been documented since the first report in 1927 ( Table 1 ) [ 14 - 21 ].…”

Human diphyllobothriasis is a widespread fish-borne zoonosis caused by the infection with broad tapeworms belonging to the genus Diphyllobothrium. In mainland China, so far 20 human cases of Diphyllobothrium infections have been reported, and the etiologic species were identified as D. latum and D. nihonkaiense based on morphological characteristics or molecular analysis. In the present study, proglottids of diphyllobothriid tapeworms from 3 human cases that occurred in Heilongjiang Province, China were identified as D. nihonkaiense by sequencing mitochondrial cytochrome c oxidase subunit I (cox1) and NADH dehydrogenase subunit 5 (nad5) genes. Two different cox1 gene sequences were obtained. One sequence showed 100% homology with those from humans in Japan. The remaining cox1 gene sequence and 2 different nad5 gene sequences obtained were not described previously, and might reflect endemic genetic characterizations. D. nihonkaiense might also be a major causative species of human diphyllobothriasis in China. Meanwhile, the finding of the first pediatric case of D. nihonkaiense infection in China suggests that infants infected with D. nihonkaiense should not be ignored.
