The majority of D. renale infections have resulted from undercooked or raw freshwater fish consumption. [en.wikipedia.org]

If the worm is eaten by a frog or fish the third stage-larva will encyst in the predator (paratenic host). [web.stanford.edu]

Since the parasite transmission usually occurs through consumption of fish and other accidental food items, investigation of the worm amongst fish-eating animals in the areas with potential circulation of the helminth life cycle, has been regarded as [semanticscholar.org]

Both frogs and fish are paratenic hosts and carnivores become infected when they eat these. ( B22 .32.w15) Infectious Agent(s) -- Non-infectious Agent(s) -- Physical Agent(s) -- General Description There is a single report of the kidney worm Dioctophyma [web.archive.org]

There are no previous records of reptiles being part of the life cycle of D. renale, although fish and amphibians normally act as paratenic hosts. This is the first report of third-stage D. renale larvae in the freshwater turtle, T. dorbigni. [ncbi.nlm.nih.gov]

Individuals with Dioctophyme renale infection typically present with unspecific symptoms including hematuria (blood in urine), nephritis, loin pain, renal enlargement, and/or renal colic (intermittent pain in the kidney area), which may result from the [en.wikipedia.org]

A Eustrongylides infection causes severe abdominal pain, often in the right lower quadrant and seldom lasting beyond 24 hours. Most patients are afebrile. Some patients vomit. [isradiology.org]

Thus, in clinical practice, when patients present with unexplained loin pain, hematuria and kidney damage, dioctophymiasis should be considered. [parasite-journal.org]

Background When painless haematuria is associated with a mass in the flank, severe anaemia and significant weight loss, renal cell carcinoma is highly suspected. [ncbi.nlm.nih.gov]

There can also be associated vomiting, weight loss, and pernicious anemia, since the parasite absorbs vitamin B 12 from the host (0.5%) Species other than D. latum probably constitute transitory intestinal infections in humans, usually lasting for only [web.archive.org]

Some patients vomit. Unless the worm is identified in the urine, accurate diagnosis is difficult. Three cases have been reported in which the worm was subcutaneous. [isradiology.org]

Although many carriers are asymptomatic, overt clinical manifestations of diphyllobothriasis can include diarrhea, epigastric pain, nausea and vomiting. There are no reports of anaemia associated with any of the northern species except D. latum. [web.archive.org]

In some areas of the world, domestic dogs, marten, coyote, and golden jackals may also have high levels of infection Experimental infection often results in violent vomition due to worms invading the stomach wall and heavy infections (i.e. a couple dozen [k-state.edu]

They cause gradual destruction of the kidney, showing clinically as renal colic and hematuria. Eustrongylides are parasites of fish-eating birds. The life cycle is very similar to that of D. renal e. [isradiology.org]

Abstract We describe a nematode larva in a subcutaneous nodule excised from a 44-year-old Chinese male who had been living in Japan for 15 years. Morphological features suggested that the worm was a dioctophimatid nematode. [ncbi.nlm.nih.gov]

In these cases worms were found in the kidneys and larvae were found in subcutaneous nodules. These cases are of unknown etiology, but are thought to have been caused by the consumption of raw fish. [web.stanford.edu]

There are also a few more recent reports of L3 larvae being found in migratory, subcutaneous nodules. [cdc.gov]

There are about 20 authenticated human infections in which the worms have been identified in subcutaneous nodules, usually in the patient's chest or abdominal wall. The adults live in the renal pelvis and are released in the urine. [isradiology.org]

Clinical Characteristics Renal colic and low back pain are the usual presenting symptoms, accompanied by hematuria and pyuria. An adult worm may be recognized in the urine. Appendicitis is often the clinical diagnosis. [isradiology.org]

Urinalysis will likely show hematuria blood tests may reveal eosinophilia. Likely because of the rarity of human cases, there is no standard treatment for D. renale infection in humans. [en.wikipedia.org]

Back to top There has been some confusion about the history of discovery of D. renale but formal research investigating the life cycle of this parasite was started as early as 1782. [web.stanford.edu]

There has been some confusion about the life history of D. renale but research by Karmanova (1959, 1960) and Mace (1974) indicates that only one intermediate host-an oligochaete (earthworms and related aquatic forms) -- is required to complete the life [web.archive.org]
