| an epidemiological study of metagonimiasis along the upper reaches of the namhan river. | an epidemiological study of metagonimus infection was undertaken along the upper reaches of the namhan river, with special consideration on the species (type) of the worms collected from humans. eggs of metagonimus spp. were detected from 15 (9.7%) of 154 people examined in umsong-gun, and from each infected person (5 cases) 6,015-24,060 worms (mean 13,233) were recovered after treatment with praziquantel (10 mg/kg). eggs were also detected from 37 (48.1%) of 77 people in yongwol-gun, from whom ... | 1993 | 8343462 |
| life cycle of genarchopsis goppo (trematoda: derogenidae) from nara, japan. | a cystophorous cercaria obtained from semisulcospira libertina (gould) from tobihino, nara, honshu, japan, was used to experimentally infect a freshwater goby rhinogobius sp. or via the copepods mesocyclops leuckarti (claus), thermocyclops hyalinus (rehberg), and eucyclops sarrulatus (fisher). it was shown to grow into genarchopsis goppo ozaki, 1925. the parasite was found to occur as a natural infection in the stomach of rhinogobius sp. or and odontobutis obscura (temminck and schlegel) from to ... | 2001 | 11780829 |
| [an epidemiological suryey of echinostoma hortense infection in chongsong-gun, kyongbuk province] | an epidemiological study was performed to know the infection status of e. hortense among the human residents and fish intermediate hosts in chongsong-gun, kyongsangbuk-do. out of 263 people examined, 59(22.4 per cent) were positive for the eggs of e. hortense. total 152 fresh water tishes (9 species) were examined, and odontobutis obscura interrupta, misgurnus angullicaudatus and squalidus coreanus were found to harbour the metacercariae of e. hortense. juvenile or adult e. hortense were expelle ... | 1988 | 12811048 |
| [experimental and epidemiological studies on the life cycle of echinostoma hortense asada, 1926 (trematoda: echinostomatidae)] | recently there have been some reports on human infections of echinostoma hortense in korea. it was found that a few species of freshwater fishes were playing the role of the second intermediate host of e. hortense. however, molluscan intermediate host has not been identified yet in korea. the present study aimed to establish the life cycle of e. hortense in laboratory. experimental studies such as egg production from the rat, development of the eggs in vitro, exposure of miracidia to freshwater ... | 1986 | 12886089 |
| [echinostoma hortense metacercariae naturally encysted in odontobutis obscura interrupta (a freshwater fish) and experimental infection to rats] | the metacercariae of an echinostomatid fluke were detected from a freshwater fish, odontobutis obscura interrupta caught from the seom river system, wonseong-gun, kangwon-do, and experimenally infected into rats to obtain the adult worms for the species identification. a total of 32 metacercariae was detected from 10 fishes (27.8 percent) out of 36 o. obscura interrupta caught from the river. the average size of metacercariae was 153.4 x 149.0 micrometer. also, it was uniquely specific that thic ... | 1985 | 12888665 |
| life cycle of coitocoecum plagiorchis (trematoda: digenea: opecoelidae). | the life cycle of coitocoecum plagiorchis ozaki, 1926 (coitocaecum is an incorrect subsequent spelling) was studied in the field and laboratory. the study was conducted at the futatsu river and the chikugo river, kyushu, japan. adults of c. plagiorchis were obtained from fishes coreoperca kawamebari, rhinogobius spp. and odontobutis obscura. cotylomicrocercous cercariae with a two-point stylet (=cercaria distyloides faust, 1924) were detected in pleurocerid snails (semisulcospira spp.). metacerc ... | 2005 | 16043390 |
| redescription of trypanosoma ophiocephali chen 1964 (kinetoplastida: trypanosomatina: trypanosomatidae) and first record from the blood of dark sleeper (odontobutis obscura temminck and schlegel) in china. | during the parasite fauna investigation within 2004 and 2005, the freshwater fish trypanosomes were isolated from the blood of dark sleeper (odontobutis obscura temminck and schlegel) and snakehead fish (ophiocephalus argus cantor) from niushan lake, hubei province, china. blood trypomastigotes were used for light microscopy investigations. the detailed descriptions of three morphological groups of the genus trypanosoma: trypanosoma sp. i and trypanosoma sp. ii found in blood of o. obscura, and ... | 2006 | 16896653 |
| two novel myxosporean species (myxosporea: bivalvulida), myxobolus marumotoi n. sp. and cardimyxobolus japonensis n. sp., from the dark sleeper, odontobutis obscura, in japan. | two new myxosporean species, myxobolus marumotoi n. sp. and cardimyxobolus japonensis n. sp. (myxozoa: myxosporea: bivalvulida), are described from the dark sleeper, odontobutis obscura, in japan, based on their morphological and molecular characterizations. plasmodia of m. marumotoi n. sp. (myxobolidae) grew in the myofiber of trunk muscles, forming pseudocysts. the rounded spore was relatively large, measuring 13.3-15.0 μm (average 13.8) in length, 14.2-15.0 μm (14.6) in width, and 10.0-11.7 μ ... | 2014 | 24481907 |
