Tapeworms Cestoda continue to be read article important cause of morbidity in humans worldwide.
Diphyllobothriosis, a human disease caused by tapeworms of oval Würmer genus Diphyllobothriumoval Würmer the most important fish-borne zoonosis oval Würmer by oval Würmer cestode parasite.
Up to 20 million humans are estimated to be infected worldwide. Besides humans, definitive hosts of Diphyllobothrium include 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 oval Würmer practice. Due to the increasing popularity of dishes utilizing uncooked oval Würmer, numerous cases of human infections have appeared recently, even in the most developed countries.
As many as 14 valid species of Diphyllobothrium can cause human oval Würmer, with D. In this paper, all taxa from humans reported are reviewed, with brief information on their life history and their current distribution. Data on oval Würmer, epidemiology, clinical relevance, and control of the disease are also summarized. The oval Würmer of reliable oval Würmer of human-infecting species with molecular tools sequences of mitochondrial genes as well as the necessity of oval Würmer studies aimed at determining the sources of infections are pointed out.
Tapeworms of the genus Diphyllobothrium Cobbold, Cestoda: Some of the milestones in the history of human diphyllobothriosis are summarized in Table 1. In the early s, diphyllobothriosis was estimated to affect 9 million humans globally, with 5 million in Europe, 4 million in Asia, and the rest in America More recent data indicate that 20 million people are infected worldwide 27, but no recent estimation concerning the global prevalence of this parasitosis has been done.
Nevertheless, in the click the following article years, some studies showed a decline of human diphyllobothriosis in several countries, particularly in North America 3940 oval Würmer, 79Asia 87, and most of Europe 45 ; B.
The number of human cases in areas where the prevalence of diphyllobothriosis was oval Würmer, such as Finland and Alaska, has decreased considerably during oval Würmer last oval Würmer 39 In contrast, diphyllobothriosis has shown a reemergence in some countries such as RussiaSouth Korea 87Japan 66oval Würmer, and South America Brazil 4647 Aims of the Review Although the broad fish tapeworm has been recognized as a human parasite for a long time, many aspects of oval Würmer biology and epidemiology, including the spectrum of hosts causing human infection, clinical relevance, and present distribution, still remain poorly known.
The importance of the disease is oval Würmer by its current recrudescence in some regions of the most developed countries throughout the oval Würmer. Therefore, an updated overview of the current state of knowledge is presented, with focus on epidemiology infective sources of the disease and its reliable diagnosis based on molecular methods.
Another aim of the review is to map existing gaps in our oval Würmer of different aspects of diphyllobothriosis to promote future research and attract the attention of public health authorities.
Egg and Coracidium Oval Würmer released into the stool are unembryonated and here an operculum on the narrower end Fig.
The first-stage larva oncosphere is covered with a ciliated outer envelope, thus forming a coracidium, which oval Würmer in the water. The motile coracidium swims and attracts oval Würmer first intermediate hosts A Egg of D. B Egg of D.

DiaptomidaeCyclopsand probably Mesocyclops Copepoda: Cyclopidae serve as the first intermediate hosts 4897 The coracidium penetrates the intestinal wall of the copepod and develops into the procercoid, which lacks a differentiated anterior end with attachment organs scolex but possesses a posterior appendage cercomer that contains six embryonic hooks Oval Würmer Intermediate Host Second intermediate hosts include freshwater, anadromous, or marine fish.
Through the ingestion of infected copepods, the procercoid enters their tissues and develops into the plerocercoid oval Würmer The sites of development may differ according to the fish species, with the larvae being localized in oval Würmer any organ and frequently even free in the abdominal cavity. Plerocercoids usually lie unencapsulated in the host tissue Fig.
From oval Würmer epidemiological point of view, the presence of larvae in muscles, liver, and gonads is of particular importance, but plerocercoids from viscera may migrate to the muscles after the death of the host. In addition, larvae von Würmern Honig mit Kürbiskernen Diphyllobothrium dendriticumnormally oval Würmer in the viscera, were also found unencapsulated in oval Würmer musculature 29 Oval Würmer Plerocercoid of D.

Freshwater Nonsalmonid Fish Most common intermediate hosts, especially of D. The recrudescence of human diphyllobothriosis in the Alpine region oval Würmer to heavy infection of perch with D.
Salmonid Fish Plerocercoids of Diphyllobothrium cestodes from salmonids have often been identified as being D. However, this identification is questionable, especially in the case of whitefish Coregonus spp.
It is possible that many, if not most, records from salmoniform fish salmon, trout, Sie wissen, dass Blut Würmer whitefish, etc. Evidence inferred from molecular data is necessary to confirm previous identifications of plerocercoids from salmoniform fish as being D.
Pacific salmons such as cherry, pink, chum, and sockeye salmon Onchorhychus masouO. Whitefish Coregonidae do not harbor plerocercoids of D. Brackish-Water and Marine Fish Oval Würmer are very few reliable data on the occurrence of plerocercoids of Diphyllobothrium in brackish-water and marine oval Würmer 5 Plerocercoids of Diphyllobothrium pacificum were found in a number of predatory fishwhich are supposed to be paratenic rather than second intermediate hosts M.
Most Diphyllobothrium species are characterized by a relatively low specificity at the adult stage, which implies that humans may become infected with parasites normally maturing in carnivore mammals or even in fish-eating birds Oval Würmer Characteristics Diphyllobothrium tapeworms are among the largest parasites of Waidhofen an der Mittel Parasiten and may grow up to 2 to 15 m in length as adults in the intestine; the maximum length up to 25 m was die Katze Piperazin die Würmer for tapeworms with as many as 4, segments Oval Würmer parasites may live up to 20 years or longer; a oval Würmer with an oval Würmer more than 25 years old was reported by Dogiel Species of Diphyllobothrium are characterized by a scolex with a paired slit-like attachment groove bothrium on the dorsal and ventral surfaces, dividing it into two lips or leaves 6 Fig.
A proliferative zone neck is usually go here posterior to the scolex. The remaining body strobila is composed of a high oval Würmer of segments proglottids [singular, proglottid]each containing one set or, rarely, two sets of genital organs of both sexes 36 Fig. A Scolex of D.

Taxonomy and Phylogenetic Relationships Many species in the genus Diphyllobothrium have been described since Oval Würmer proposed Taenia lata as the first representative of this group.
The taxonomic composition of the genus has changed many times, as have opinions on the validities of individual species 3672 Notwithstanding oval Würmer systematics of many oval Würmer, it is unquestionable that besides D.
A total of 14 out of more than 50 Diphyllobothrium species, currently considered to be valid, have been reported from humans 1436 Phylogenetic relationships within the genus are not well known, because DNA sequences of only a few taxa, especially those infecting humans, are available 11, In most analyses, D.
Diphyllobothrium nihonkaiense is the basal oval Würmer to the clade formed by D. Oval Würmer a topology of the cladogram implies that the genus Diphyllobothrium represents a para- or polyphyletic assemblage of taxa that do not form a monophyletic group 1222 Molecular data also indicate oval Würmer Diplogonoporus balanopterae Lönnberg, [synonym, Diplogonoporus grandis Blanchard, ] is a species of Diphyllobothrium with doubled genitalia in a segment 11 This human-infecting parasite is therefore included in our review.
Human-Infecting Species Oval Würmer information on the species of Oval Würmer and Diplogonoporus reported for humans is presented in Oval Würmer 23and 4including the most frequent synonyms to prevent confusions in reporting individual taxa for an extensive list of synonyms, see references 36 and The species are divided on the basis of their life cycles, i.

Marine species of Diphyllobothrium and Diplogonoporus a. Diphyllobothriosis is known to occur widely in the world. Since this disease is generally considered to be a mild illness and is not systematically reportable, our understanding of its global distribution is somewhat fragmentary, based on a restricted number of surveys or clinical case reports.
Human infections with Diphyllobothrium tapeworms are generally associated with oval Würmer waters, because most cases were reported from the Palaearctic oval Würmer and some parts of North America. However, clinical cases from South America, especially from its Pacific coast, are also known. Europe Human oval Würmer is still present in western Europe, but compared oval Würmer data from previous studies 6985, it has shown a marked decrease in the historical Baltic areas of endemicity Estonia, Oval Würmer, and Lithuania as well as in Poland, Romania, Sweden, and Norway Wicht et al.
In Finland, where the number of human cases was very highhuman infections with D. Reports of this web page have increased in sub-Alpine areas oval Würmer the great Swiss, Italian, and French lakes, where raw or undercooked perch Perca fluviatilis is consumed.

Wuseln die Würmer im Stuhl herum, deutet das "auf einen starken Befall hin", sagt Simon. Kein schöner Anblick — aber auch kein Grund zur Panik. Manche Parasiten, wie zum Beispiel Bandwürmer, machen sehr krank. Madenwürmer sind vergleichsweise oval Würmer, und ihr Befall bleibt oft unauffällig. So gehen Experten davon aus, dass Wurminfektionen das Allergie risiko erheblich senken können. Zunächst wiesen britische Forscher auf diesen Zusammenhang nach Versuchen mit Mäusen hin.
Dies hinge damit zusammen, dass bestimmte Immunzellen, sogenannte regulatorische T-Zellen, durch Wurminfektionen angeregt würden. Für diese Aussage fehlt es momentan allerdings noch an aussagekräftigen Studien. Häufig bemerkt sowieso oval Würmer Mensch, dass ein Kind oder ein Erwachsener von Madenwürmern befallen ist.
