| mass mortality of giant abalone haliotis gigantea caused by a francisella sp. bacterium. | in february 2005, a mass mortality of giant abalone haliotis (nordotis) gigantea gmelin, 1791 occurred on a private abalone farm in shimane prefecture, japan. the cumulative mortality rate reached about 84%. in histological observations, bacteria-like spherical particles were found in affected animals, suggesting a bacterial infection. many of the bacteria-like particles were found in the cells that were presumably host phagocytes. dna was extracted from the hemolymph of a diseased abalone and a ... | 2010 | 20402232 |
| francisella halioticida sp. nov., a pathogen of farmed giant abalone (haliotis gigantea) in japan. | in 2005, a francisella sp. was isolated from diseased cultured giant abalone (haliotis gigantea) in japan. the aim of this study was to clarify the taxonomic status of this francisella sp. shimane-1 isolate in relation to the four described francisella species. | 2011 | 21883728 |
| formosa haliotis sp. nov., a brown-alga-degrading bacterium isolated from the gut of the abalone haliotis gigantea. | four brown-alga-degrading, gram-stain-negative, aerobic, non-flagellated, gliding and rod-shaped bacteria, designated lmg 28520t, lmg 28521, lmg 28522 and lmg 28523, were isolated from the gut of the abalone haliotis gigantea obtained in japan. the four isolates had identical random amplified polymorphic dna patterns and grew optimally at 25 °c, at ph 6.0-9.0 and in the presence of 1.0-4.0 % (w/v) nacl. phylogenetic trees based on 16s rrna gene sequences placed the isolates in the genus formosa ... | 2015 | 26354496 |
| the role of hybridization in improving the immune response and thermal tolerance of abalone. | recently, frequent death of cultured abalone drew our attention to the stress tolerance of abalone. hybridization is an effective way of genetic improvement in aquaculture, which can introduce improved traits to the hybrids. in this study, we challenged the hybrids between haliotis discus hannai and haliotis gigantea, and their parents with bacteria (vibrio harveyi, vibrio alginolyticus and vibrio parahemolyticus), then held them at 20 °c and 28 °c, survival rates of the parental populations and ... | 2014 | 24794582 |
