| studies on the geographical distribution of the lung fluke, paragonimus westermani (kerbert, 1878) in the southern prefectures of the kinki district, japan: observations on the incidence of encysted larvae of p. westermani in geothelphusa dehaani in higashi-yoshino area, nara prefecture. | | 1983 | 6632458 |
| diploid paragonimus westermani: the experimental completion of its life-cycle. | experimental completion of the life-cycle of paragonimus westermani (trematoda: troglotrematidae) (diploid type) from egg to adult has been achieved in the laboratory for the first time. a dog was fed metacercariae of p. westermani from naturally infected freshwater crabs. geothelphusa dehaani. the adult flukes were recovered and their eggs were incubated in water at 28 degrees c, hatching after 20 days. laboratory reared marsh snails, semisulcospira libertina, were exposed to miracidia from emb ... | 1993 | 8132968 |
| [a case of paragonimiasis westermani]. | a 45-year-old man, who had eaten fried fresh water crabs (geothelphusa dehaani), was admitted to our hospital because of productive cough and bloodysputum. blood chemistry showed increased levels of white blood cells and c-reactive protein, but peripheral blood eosinophil counts and serum ige values were not elevated. chest roentgenogram and chest computed tomographic scan revealed infiltration of the right middle and left upper lung fields. he was diagnosed as having pneumonia, but his symptoms ... | 1998 | 9805915 |
| infection by paragonimus miyazakii cercariae of their crab hosts, geothelphusa dehaani, by percutaneous penetration. | identification of the transmission routes of the trematode parasite paragonimus miyazakii into different intermediate hosts would help to explain the natural distribution of the parasite. the behavior of p. miyazakii cercariae released from snails into water and in the presence of a living host or a whole crab leg was observed by stereoscopic or light microscopy at various times after exposure started. on encountering a crab leg or cheliped, the cercariae became entangled with the host via mucoi ... | 2000 | 11191913 |
| effects of arsenic on gonadal development in freshwater crab, somanniathelphusa pax, in vietnam and geothelphusa dehaani in japan. | to estimate the influence of water contamination by arsenic (as) on reproduction of crustaceans in vietnam, we collected wild freshwater crab somanniathelphusa pax from the mekong delta area in vietnam, investigated gonadal development, and measured as concentration in hepatopancreas. in female crab, vitellogenesis was delayed in association with the increase of as accumulation in hepatopancreas, whereas there was no significant correlation between testicular development and as accumulation in m ... | 2008 | 18548346 |
| detection of paragonimus metacercariae in the japanese freshwater crab, geothelphusa dehaani, bought at retail fish markets in japan. | | 2009 | 19628917 |
| a rare case of paragonimiasis miyazakii with lung involvement diagnosed 7 years after infection: a case report and literature review. | we report a rare case of pulmonary paragonimiasis caused by paragonimus miyazakii that showed pulmonary manifestations and a long-term clinical course after infection. a 45-year-old japanese male developed cough and dyspnea in 2004 and was diagnosed with eosinophilic pneumonia. he had been treated with low-dose oral corticosteroid for 7 years. he recalled that he had consumed a large amount of raw freshwater crab (geothelphusa dehaani) several weeks before he had been admitted for the first time ... | 2015 | 25771073 |
| current status of lung fluke metacercarial infection in freshwater crabs in the kawane area of shizuoka prefecture, japan. | feline cases of lung fluke infection were recently reported in the upper basin of the oi river in shizuoka prefecture. the causative species of these cases were not identified, although a field survey conducted about 40 years ago in this area demonstrated the prevalence of paragonimus miyazakii metacercariae in intermediate host crabs. to clarify the current status of lung fluke metacercarial infection in host crabs, we collected the japanese freshwater crab or sawagani, geothelphusa dehaani, at ... | 2013 | 23076034 |
| developing a food web-based transfer factor of radiocesium for fish, whitespotted char (salvelinus leucomaenis) in headwater streams. | we developed a food web-based transfer factor (tfweb) to study contaminant movements from multiple prey items to a predator based on the dietary contributions of prey items with their respective contamination levels. tfweb was used to evaluate the transfer of (137)cs into whitespotted char (salvelinus leucomaenis) from the trophic structure of a stream-riparian ecosystem in headwater streams draining a japanese cedar forest. we also examined the applicability of this method by comparing sites wi ... | 2017 | 28390308 |
| praobdellidae (hirudinida: arhynchobdellida) is not specific only to the mucous-membrane after all: discovery of a praobdellid leech feeding on the japanese freshwater crab geothelphusa dehaani. | praobdellid leech species have been known to infest vertebrate mucous-membrane; some of them have been assumed to be invertebrate bloodsuckers. praobdellid individuals were found feeding on the japanese freshwater crab, geothelphusa dehaani, at mt. tsukuba, ibaraki prefecture, japan. the leech had inserted its head into the intersegmental membrane between the crab's carapace and legs. our findings represent a first invertebrate host record for praobdellid leeches. additionally, molecular phyloge ... | 2017 | 28137668 |
| the mitochondrial genome of the japanese freshwater crab, geothelphusa dehaani (crustacea: brachyura): evidence for its evolution via gene duplication. | the translocation of trna genes has occurred frequently among multiple independent arthropod lineages. however, the mechanisms of such gene rearrangement are still unclear. in this study we sequenced the nearly complete mitochondrial genome of the japanese freshwater crab, geothelphusa dehaani (decapoda, brachyura, potamidae). its size is relatively large (app. 24 kb) for higher animal mtdna and is due to the presence of many intergenic noncoding sequences (igns), one of which is a large repeat ... | 2005 | 16039805 |
| sexual disruption in the freshwater crab (geothelphusa dehaani). | to clarify the effect of environmental endocrine disruptors on the induction of secondary sexual characteristics in wild animals, we observed 1,527 male and 1,847 female specimens of sexually mature japanese freshwater crabs, geothelphusa dehaani, collected at 12 sample points from 10 rivers in sasebo city, nagasaki prefecture, japan. the results obtained were as follows: abnormal males, with external appearance of a complete male, but having female genital openings, were observed at frequencies ... | 2005 | 21676743 |
