| neoparamoeba branchiphila n. sp., and related species of the genus neoparamoeba page, 1987: morphological and molecular characterization of selected strains. | a total of 18 neoparamoeba strains were characterized both morphologically and using the ssu rrna gene sequences as molecular markers. nine were isolated from gills of farmed atlantic salmon, salmo salar l., six from sediments sampled in areas of sea-cage farms and three from net material of sea-cages. the newly obtained sequences extended substantially the dataset of neoparamoeba strains available for phylogenetic analyses, which were used to infer taxonomic relatedness among 32 strains morphol ... | 2005 | 15660793 |
| neoparamoeba perurans n. sp., an agent of amoebic gill disease of atlantic salmon (salmo salar). | amoebic gill disease (agd) is a potentially fatal disease of some marine fish. two amphizoic amoebae neoparamoeba pemaquidensis and neoparamoeba branchiphila have been cultured from agd-affected fish, yet it is not known if one or both are aetiological agents. here, we pcr amplified the 18s rrna gene of non-cultured, gill-derived (ncgd) amoebae from agd-affected atlantic salmon (salmo salar) using n. pemaquidensis and n. branchiphila-specific oligonucleotides. variability in pcr amplification le ... | 2007 | 17561022 |
| Neoparamoeba branchiphila infections in moribund sea urchins Diadema aff. antillarum in Tenerife, Canary Islands, Spain. | A total of 109 sea urchins from 3 species collected in 2 localities off the coast of Tenerife Island, Spain, were examined for the presence of free-living amoebae in their coelomic fluid. Amoeba trophozoites were isolated exclusively from moribund individuals of long-spined sea urchins Diadema aff. antillarum (Philippi) (Echinoidea, Echinodermata) that manifested lesions related to sea urchin bald disease on their tests (16 out of 56 examined). No amoebae were detected in Arbacia lixula (L.) and ... | 2011 | 21932534 |
