| a novel spiroplasma pathogen causing systemic infection in the crayfish procambarus clarkii (crustacea: decapod), in china. | a novel disease of crayfish procambarus clarkii appeared in the summer of 2004 in freshwater aquaculture in jiangsu province of china. light and transmission electron microscopy (tem), molecular biological methods and in vitro culture were used to identify the pathogen. the agent was unique in having a helical morphology and rotary motility as observed by phase-contrast light microscopy and was found in haemolymph, muscles, nerves and connective tissues by smear method and tem. ultra-thin sectio ... | 2005 | 16000238 |
| symbiotic bacteria in gills and guts of chinese mitten crab (eriocheir sinensis) differ from the free-living bacteria in water. | aquatic animals have a close relationship with water, but differences in their symbiotic bacteria and the bacterial composition in water remains unclear. wild or domestic chinese mitten crabs (eriocheir sinensis) and the water in which they live were collected from four sampling sites in jiangsu and shanghai, china. bacterial composition in water, gills or guts of e. sinensis, were compared by high-throughput sequencing using 16s rrna genes. analysis of >660,000 sequences indicated that bacteria ... | 2016 | 26820139 |
| fatty acid composition evaluation of edible parts of eriocheir sinensis in intensive ponds of gucheng waters. | in gucheng lake, jiangsu province, china, randomly selected crabs were fed 2 diet types. crab crude oil methyl ester analysis was performed using gas chromatography-mass spectrometry. fatty acid compositions in the 3 edible parts of a crab - the hepatopancreas, gonad, and muscle - were analyzed. c16:1 and c18:2 were significantly higher in most commercial pellet feed-feeding crabs than in small trash fish-feeding crabs, while the opposite was observed for eicosapentaenoic and docosahexaenoic aci ... | 2015 | 26125730 |
