| temporal and spatial variation on heavy metal concentrations in the oyster ostrea equestris on the northern coast of rio de janeiro state, brazil. | heavy metal (cd, cr, cu, fe, mn, ni, pb, and zn) concentrations were determined by icp-aes in ostrea equestris from three beaches (barra do furado, buena, and ponta do retiro) on the northern coast of rio de janeiro state. the average concentration was 0.8 +/- 0.18, 0.4 +/- 0.21, 58 +/- 25.6, 249 +/- 52.3, 11 +/- 1.31, 0.55 +/- 0.16, 0.13 +/- 0.11, and 1131 +/- 321 microg x g(-1) dry weight for cd, cr, cu, fe, mn, ni, pb, and zn respectively. significant spatial variation (p < 0.05) between the ... | 2005 | 16025905 |
| bonamia perspora n. sp. (haplosporidia), a parasite of the oyster ostreola equestris, is the first bonamia species known to produce spores. | examination of the oyster ostreola equestris as a potential reservoir host for a species of bonamia discovered in crassostrea ariakensis in north carolina (nc), usa, revealed a second novel bonamia sp. histopathology, electron microscopy, and molecular phylogenetic analysis support the designation of a new parasite species, bonamia perspora n. sp., which is the first bonamia species shown to produce a typical haplosporidian spore with an orifice and hinged operculum. spores were confirmed to be ... | 2006 | 16872291 |

| observation of a bonamia sp. infecting the oyster ostrea stentina in tunisia, and a consideration of its phylogenetic affinities. | the small non-commercial oyster ostrea stentina co-occurs with commercially important ostrea edulis in the mediterranean sea, yet its disposition with respect to the destructive pathogens bonamia ostreae and marteilia refringens is unknown. we began an evaluation of the bonamia spp. infection status of o. stentina from hammamet, tunisia, in june 2007 using polymerase chain reaction diagnostics followed by histology and in situ hybridization. of 85 o. stentina sampled, nine were pcr-positive for ... | 2010 | 20036670 |
