| [tegumental ultrastructure of juvenile and adult echinostoma cinetorchis]. | the tegumental ultrastructure of juvenile and adult echinostoma cinetorchis (trematoda: echinostomatidae) was observed by scanning electron microscopy. three-day (juvenile) and 16-day (adult) worms were harvested from rats (sprague-dawley) experimentally fed the metacercariae from the laboratory-infected fresh water snail, hippeutis cantori. the worms were fixed with 2.5% glutaraldehyde, processed routinely, and observed by an isi korea ds-130 scanning electron microscope. the 3-day old juvenile ... | 1992 | 1627505 |
| experimental life history of echinostoma cinetorchis. | the life history of echinostoma cinetorchis was completed in the laboratory using hippeutis cantori as the first and second intermediate host. the incubation for maturation of eggs and hatching of miracidia took 24 days at 28 degrees c. on the 66th day after miracidial challenge, 16 snails were crushed and examined for the presence of e. cinetorchis larvae. the metacercariae were detected in all of the snails, and from three of them were found the rediae and cercariae. the morphological characte ... | 1990 | 2271499 |
| [cercarial shedding of echinostoma cinetorchis and experimental infection of the cercariae to several kinds of snails]. | the development of echinostoma cinetorchis in several snail species reared in laboratory aquaria was observed. the eggs from adult flukes collected from the intestine of rats were cultivated to miracidia, and exposed to hippeutis sp. snails. observations were made for cercarial shedding from the exposed snails. the cercariae shed from the snails were again exposed to several species of fresh water snails in order to observe metacercarial formation in the snails and their infectivity to final hos ... | 1989 | 2486931 |

| poultry as reservoir hosts for fishborne zoonotic trematodes in vietnamese fish farms. | fishborne zoonotic trematodes (fzt) are widespread in vietnam and southeast asia. it is now recognized that the risk of being infected from eating raw fish dishes applies not only to humans, but also to domestic animals (e.g., cats, dogs, and pigs) and fish-eating birds. the role of ducks and chicken, commonly raised on fish farms, as reservoir hosts, however, has not been adequately investigated. to study this question, chickens and ducks from integrated poultry-fish farms in nghia lac and nghi ... | 2010 | 20149548 |
| evaluation of the role of rats as reservoir hosts for fishborne zoonotic trematodes in two endemic northern vietnam fish farms. | fishborne zoonotic trematodes (fzts) pose a food safety risk for the aquaculture industry in vietnam. the risk of being infected from eating raw fish applies not only to humans but also to domestic animals which can serve as reservoir hosts in fish farms. the role of rodents, commonly found in fish farms, as reservoir hosts has not been adequately evaluated. to study this question, commensal and rice field rats were collected from fish farms in nghia lac and nghia phu communes, nam dinh province ... | 2012 | 22592535 |
