| studies on cercariae from the kuwait bay. vi. description and surface topography of cercaria kuwaitae vi sp. n. (trematoda: haplosplanchnidae). | a new haplosphlanchnid cercaria, cercaria kuwaitae vi sp. n., was found in the prosobranch snail cerithidea cingulata in the kuwait bay. details are presented on the morphology and behavior of the cercaria and the encystment process. the new cercaria is a biocellate, distome, with a prominent single sac-like intestinal cecum extending well posterior to the ventral sucker and develops in simple sporocysts. it differ from known haplosplanchnid cercariae in the absence of finger-like processes on t ... | 1995 | 8528620 |
| studies on cercariae from kuwait bay. xi. description and surface topography of cercaria kuwaitae xi sp.n. (digenea: echinostomatidae). | a new echinostome cercaria, cercaria kuwaitae xi sp.n., from the prosobranch gastropod cerithidea cingulata (gmelin) from kuwait bay is described. the new cercaria is characterized by 23 collar spines and primary excretory tubules with distinct diverticula. the cercaria encysts in the snail host and is similar to those of acanthoparyphium sp. the surface topography of the redia, cercaria and metacercarial cyst wall is studied by scanning electron microscopy. this is the first echinostome cercari ... | 1999 | 10585649 |
| temporal variations in the infection of a population of cerithidea cingulata by larval trematodes in kuwait bay. | the prosobranch gastropod cerithidea cingulata (gastropoda: potamididae) in kuwait bay was examined for larval trematode infections over a 17-month period. a total of 2537 snails were examined and 1265 (49.9%) found to be infected with one or more species of trematodes. the component community in the snail comprised 12 species representing the families cyathocotylidae (2), echinostomatidae (2), haplosplanchnidae (1), heterophyidae (2), microphallidae (1), philophthalmidae (2), plagiorchiidae (1) ... | 2000 | 10831049 |
| malacological survey in phang-nga province, southern thailand, pre- and post-indian ocean tsunami. | three malacological surveys were conducted in the takua pa district of phang-nga province, southern thailand, before and after the indian ocean tsunami disaster. twenty-nine species of fresh- and brackish-water snails were found, in which 10 species of freshwater snails were present, including live pila polita; 8 species were of medical importance. two brackish-water snails, nerita articulata and littorinopsis scabra, were absent after the tsunami disaster, while brackish-water cerithidea cingul ... | 2006 | 17547062 |
| characterization of fucose-binding lectins in rock- and mud-dwelling snails inhabiting kuwait bay. | two novel lectins that bind selectively to trematode-associated fucosylated determinants have been characterized and purified from the hemolymph of wild-type rock-dwelling turbo coronatus and mud-dwelling cerithidea cingulata snails inhabiting kuwait bay. both lectins were separately purified from the hemolymph of t. coronatus (designated tc lectin) and c. cingulata (designated cc lectin) by affinity chromatography on immobilized l-fucose-agarose columns and elution with a gradient of 0.1-1 m l- ... | 2009 | 19159829 |
| molecular identification of probolocoryphe uca (sarkisian, 1957; digenea: microphallidae) from kuwait bay using its1 and its2 sequences. | probolocoryphe species occur primarily as intestinal parasites of birds and mammals. infection of the crab nanosesarma minutum with the metacercarial cyst stages of probolocoryphe uca is common in kuwait bay. in this study, the snail cerithidea cingulata was used to determine if it would serve as first intermediate host in the parasite's life cycle. to determine the snail-crab link in the life cycle of p. uca based on rdna molecular data, ribosomal internal transcribed spacer (its) regions of th ... | 2010 | 20143090 |
| 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 |
| molecular characterization of stictodora tridactyla (trematoda: heterophyidae) from kuwait bay using rdna its and mtco1. | stictodora tridactyla is an intestinal fluke in the family heterophyidae that parasitizes shorebirds and mammals, including humans. its metacercarial cyst stage was reported in the arabian killifish, aphanius dispar, at kuwait bay. in the present study, cerithidea cingulata was found to serve as the first intermediate host of s. tridactyla. in order to establish the snail-fish link in the life cycle of s. tridactyla, complete sequences of ribosomal dna internal transcribed spacer region 1 and 2 ... | 2015 | 26268569 |
| molecular identification of austrobilharzia species parasitizing cerithidea cingulata (gastropoda: potamididae) from kuwait bay. | avian schistosomes belonging to the genus austrobilharzia (digenea: schistosomatidae) are among the causative agents of cercarial dermatitis in humans. in this paper, ribosomal and mitochondrial dna sequences were used to study schistosome cercariae from kuwait bay that have been identified morphologically as austrobilharzia sp. sequence comparison of the ribosomal dna (rdna) 28s and 18s regions of the collected schistosome cercariae with corresponding sequences of other schistosomes in genbank ... | 2012 | 22152331 |
| effects of reclamation on macrobenthic assemblages in the coastline of the arabian gulf: a microcosm experimental approach. | coastal reclamation and modifications are extensively carried out in bahrain, which may physically smother the coastal and subtidal habitats resulting in changes to abundance and distribution of macrobenthic assemblages. a microcosm laboratory experiment using three common macrobenthic invertebrates from a proposed reclaimed coastal area was preformed to examine their responses to mud burial using marine sediment collected from a designated borrow area. significant difference in numbers of survi ... | 2011 | 21185035 |
