| occurrence of a sporocyst generation of fasciola gigantica in the mollusc lymnaea rubiginosa. | thirty laboratory-reared, juvenile lymnae rubiginosa were exposed to 20 miracidia each of fasciola gigantica. eight days postinfection snails were dissected, and clearly recognizable sporocysts were recovered from the mantle collar and renal vein. behavior of sporocysts and mother rediae differed markedly. these observations contradict those of direct metamorphosis of miracidium into redia as reported by ogambo-ongoma and goodman (1976). | 1977 | 859085 |
| the freshwater snail lymnaea rubiginosa as an experimental host of angiostrongylus malaysiensis: a preliminary report. | preliminary studies have shown that lymnaea rubiginosa, a common fresh-water snail in peninsular malaysia, which is easily colonized and reared in the laboratory, is a capable experimental intermediate host for angiostrongylus malaysiensis. overall 73% of the snails tested became infected following 6 hours exposure to infective rat faeces. higher infection rates, up to 100%, and heavier worm loads, occurred among the larger sized snails. snail attrition was low except when very heavy worm loads ... | 1976 | 1027105 |

| comparative shell morphology of lymnaea (bullastra) cumingiana (pulmonata: lymnaeidae) and related taxa in the indo-pacific region. | comparative shell morphology using both quantitative and qualitative parameters was employed to investigate the taxonomic relationship between the endemic philippine species, lymnaea (bullastra) cumingiana and five other lymnaeid "species" in the indo-pacific region, namely: l. (radix) quadrasi (philippines). l. (radix) rubiginosa (indonesia), l. (radix) rubiginosa (thailand), l. (radix) viridis (guam) and l. (radix) viridis (hong kong). fifty randomly chosen adult specimens of each species were ... | 1993 | 8160068 |
| freshwater mollusks of medical importance in kalasin province, northeast thailand. | a snail survey was performed in six districts around irrigation areas of lampao dam, in kalasin province. the survey caught a total of 5,479 live snails and classed them into five families, 12 genera and 15 species, of which 7 species are suspected of transmitting human parasitic diseases. the seven species were pila polita, pomacea canaliculata, filopaludina (s.) m. martensi, bithynia (digoniostoma) siamensis goniomphalos, melanoides tuberculata, radix rubiginosa, and indoplanorbis exustus. of ... | 2005 | 16124433 |
| biological control of fasciola gigantica with echinostoma revolutum. | a field trial was carried out in west java to investigate the potential for control of fasciolosis of antagonism between larvae of fasciola gigantica and echinostoma revolutum in lymnaea rubiginosa. the trial was undertaken in 26 farmers' irrigated rice fields, each chosen because it was adjacent to a cattle pen the effluent from which flowed into or was used as fertiliser in the rice field. fourteen of the fields chosen at random were retained as controls and received no treatment while in 12, ... | 2006 | 16854529 |
| freshwater mollusks at designated areas in eleven provinces of thailand according to the water resource development projects. | the study was conducted at 75 collecting loci in 15 districts of 11 provinces in thailand during 1999-2004. a total of 12,079 live mollusks were collected, 11,874 were snails and 205 were clams. the snails were comprised of 39 species and classified into 9 families: ampullariidae, bithyniidae, buccinidae, potamiopsidae, stenothyridae, thiaridae, viviparidae, planorbidae and lymnaeidae. the clams were comprised of 14 species classified into 2 families: amblemidae and corbiculidae. fifteen species ... | 2007 | 17539279 |
| snails and trematode infection after indian ocean tsunami in phang-nga province, southern thailand. | the tsunami and non-tsunami affected areas of takua pa district, phang-nga province were investigated for fresh- and brackish-water snails that transmit human parasitic diseases during 2006 and 2007. among 46 snail species found, 17 species of 8 families were freshwater snails, 28 species of another 7 families were brackish-water snails, and 1 species was a land snail. of these species, 11 freshwater snails, 4 brackish-water snails and 1 land snail were of medical importance. the fresh-water sna ... | 2010 | 20578482 |
| rapid identification of lymnaeid snails and their infection with fasciola gigantica in thailand. | freshwater snails of the family lymnaeidae are the intermediate hosts of the liver fluke fasciola worldwide. while distinct species have been identified at the molecular level in other parts of the world such data have not been published for thailand. in this study we collected lymnaeidae from different localities across thailand and analyzed their 16s rdna sequences as a molecular signature for classification. in addition to the ubiquitous radix rubiginosa, we have confirmed the presence of aus ... | 2010 | 20685274 |
| current status of fasciolosis in vietnam: an update and perspectives. | vietnam is recognized to be endemic for fasciolosis. however, most of the available publications have not been published in international journals. this review is based on national and international vietnamese publications and highlights the current status of fasciolosis in vietnam. it also provides some information available for neighbouring countries. updated data on responsible species, distribution, transmission and control aspects are summarized. the central region of vietnam is reported as ... | 2016 | 26564097 |
| morphological and molecular characterization of lymnaeid snails and their potential role in transmission of fasciola spp. in vietnam. | freshwater snails of the family lymnaeidae play an important role in the transmission of fascioliasis worldwide. in vietnam, 2 common lymnaeid species, lymnaea swinhoei and lymnaea viridis, can be recognized on the basis of morphology, and a third species, lymnaea sp., is known to exist. recent studies have raised controversy about their role in transmission of fasciola spp. because of confusion in identification of the snail hosts. the aim of this study is, therefore, to clarify the identities ... | 2013 | 24516270 |
| failure of irradiated echinostoma audyi and hypoderaeum dingeri to sensitize lymnaea rubiginosa snails. | attempts to induce acquired resistance in lymnaea rubiginosa snails against the echinostomes echinostoma audyi and hypoderaeum dingeri by means of irradiated miracidia were unsuccessful, although lie and coworkers using similar methods had recently sensitized biomphalaria glabrata against echinostoma lindoense (1975a). in contrast to the b. glabrata-e. lindoense system, in lymnaea rubiginosa the amebocytic response to irradiated parasites was slow: irradiated e. audyi sporocysts were encapsulate ... | 1977 | 607426 |
