| molecular phylogeny and surface morphology of marine archigregarines (apicomplexa), selenidium spp., filipodium phascolosomae n. sp., and platyproteum n. g. and comb. from north-eastern pacific peanut worms (sipuncula). | the trophozoites of two novel archigregarines, selenidium pisinnus n. sp. and filipodium phascolosomae n. sp., were described from the sipunculid phascolosoma agassizii. the trophozoites of s. pisinnus n. sp. were relatively small (64-100 microm long and 9-25 microm wide), had rounded ends, and had about 21 epicytic folds per side. the trophozoites of f. phascolosomae n. sp. were highly irregular in shape and possessed hair-like surface projections. the trophozoites of this species were 85-142 m ... | 2009 | 19737195 |
| multiple isolations of a culturable, motile ichthyosporean (mesomycetozoa, opisthokonta), creolimax fragrantissima n. gen., n. sp., from marine invertebrate digestive tracts. | a fragrant, spherical, osmotrophic eukaryote was isolated 27 times from the digestive tracts of marine invertebrates collected from the northeast pacific. the isolates were cultured from 7 animal collections over a 2-year period, most from the peanut worm, phascolosoma agassizii. a small subunit ribosomal dna phylogeny placed the spherical organism within the ichthyosporea, closest to sphaeroforma arctica and pseudoperkinsus tapetis. supporting the close relationship of isolates, the sequences o ... | 2008 | 18539526 |
