oceaniserpentilla haliotis gen. nov., sp. nov., a marine bacterium isolated from haemolymph serum of blacklip abalone.an aerobic, gram-negative bacterial isolate, strain dsm 19503(t), was isolated from haemolymph serum of the blacklip abalone haliotis rubra. cells of strain dsm 19503(t) were vibrioid to spiral, motile and were able to pass through sterile filters with a pore size of 0.2 microm, indicating the small width of the bacterium. the isolate was psychrophilic, with the ability to grow at 2-8 degrees c. oxidase activity was present, whereas catalase activity was absent. the nearly complete 16s rrna gene ...200818768616
identification of a putative egg-laying hormone in neural and ovarian tissues of the black tiger shrimp, penaeus monodon, using immunocytochemistry.the existence of an egg-laying hormone (elh) was identified for the first time in the black tiger shrimp, penaeus monodon, by means of immunoenzyme and immunofluorescence techniques. this was achieved using a polyclonal antibody produced against expressed recombinant elh of the female australian blacklip abalone, haliotis rubra. the shrimp elh reactive material was found to be localised within female neurosecretory tissues and the secretory tissue of the antennal gland, but was not identified in ...200616544160
influence of elevated temperatures on the immune response of abalone, haliotis rubra.elevated water temperature can act as a stressor impacting the immune responses of molluscs, potentially increasing their susceptibility to microbial infections. abalone are commercially important marine molluscs that have recently experienced disease outbreaks caused by a herpesvirus and vibrio bacteria. sampling of wild-caught haliotis rubra showed a significant correlation between water temperature and both antiviral and antibacterial activity, with higher activity in summer than in winter mo ...201222306749
characterization of microsatellite loci in the australian blacklip abalone (haliotis rubra, leach). 200010964244
a microsatellite linkage map of the blacklip abalone, haliotis rubra.there is considerable scope for genetic improvement of cultured blacklip abalone haliotis rubra in australia using molecular marker-assisted, selective-breeding practices. such improvement is dependent on the availability of primary genetic resources, such as a genetic linkage map. this study presents a first-generation linkage map of h. rubra, containing 122 microsatellite markers typed in a single full-sib family. these loci mapped to 17 and 20 linkage groups for the male and female respective ...200617121601
comparison of n-3 polyunsaturated fatty acid contents of wild and cultured australian abalone.the fatty acid contents of wild and cultured australian adult blacklip abalone, haliotis rubra, were analysed by gas liquid chromatography. wild abalone contained significantly higher levels of total n-3 polyunsaturated fatty acids (pufa), eicosapentaenoic acid (20:5n-3), docosapentaenoic acid (22:5n-3) and alpha-linolenic acid (18:3n-3) than cultured abalone (p<0.05). the predominant n-3 pufa was docosapentaenoic acid in wild abalone, while in cultured abalone a high level of eicosapentaenoic a ...200414985187
molecular sequences of two minisatellites in blacklip abalone, haliotis rubra.in the cloning and sequencing of growth-promoting genes of the blacklip abalone, haliotis rubra (leach, 1814), two dna variable number of tandem repeats (vntrs) were identified in abalone cdna libraries. one contained a 33 bp repeat unit (5'-cccaaggtccccaaggtcagggaggcgaaggct-3') located in the 3' untranslated region of a putative growth hormone (gh) gene, and the repeat was designated as ghr. the other contained an 18 bp repeat unit (5'-acccggcgcttattagag-3') located in the 3' untranslated regio ...19979378140
occurrence of perkinsus olseni in the venus clam protothaca jedoensis in korean waters.this is the first report of the occurrence of perkinsus olseni in the venus clam protothaca jedoensis off the western and southern coasts of south korea. histological observations revealed perkinsus-like organisms in the mantle, gills, digestive tubules, and gonad. haemocytic infiltration and tissue necrosis were also observed in heavily infected clams. hypnospore formation of the perkinsus-like organism was confirmed with ray's fluid thioglycollate medium assay (rftm). when incubated in filtere ...200616764886
immunological changes in response to herpesvirus infection in abalone haliotis laevigata and haliotis rubra hybrids.australian abalone production has been affected by outbreaks of abalone viral ganglioneuritis (avg) caused by a herpesvirus (abhv). in this study, we undertook experimental transmission trials by immersion to study the abalone immune response to infection with abhv. representative cellular and humoural immune parameters of abalone, including total haemocyte count (thc), superoxide anion (so) and antiviral activity against herpes simplex virus type 1 (hsv-1), were examined in apparently healthy ( ...201323201319
abalone hemocyanin blocks the entry of herpes simplex virus 1 into cells: a potential new antiviral strategy.a marine-derived compound, abalone hemocyanin, from haliotis rubra was shown to have a unique mechanism of antiviral activity against herpes simplex virus 1 (hsv-1) infections. in vitro assays demonstrated the dose-dependent and inhibitory effect of purified hemocyanin against hsv-1 infection in vero cells with a 50% effective dose (ed50) of 40 to 50 nm and no significant toxicity. in addition, hemocyanin specifically inhibited viral attachment and entry by binding selectively to the viral surfa ...201626643336
vibrio superstes sp. nov., isolated from the gut of australian abalones haliotis laevigata and haliotis rubra.five alginolytic, facultatively anaerobic, non-motile bacteria were isolated from the gut of abalones haliotis laevigata and haliotis rubra. phylogenetic analyses based on 16s rdna data indicated that these strains are related closely to vibrio halioticoli (98 % 16s rdna sequence similarity). dna-dna hybridization and fluorescent amplified fragment length polymorphism fingerprinting demonstrated that the five strains constituted a single species that was different from all currently known vibrio ...200314657109
