Plesiocystis pacifica
species of Deltaproteobacteria
Plesiocystis pacifica is a species of marine myxobacteria. Like other members of this order, P. pacifica is a rod-shaped Gram-negative bacterium that can move by gliding and can form aggregates of cells called fruiting bodies. The species was first described in 2003, based on two strains isolated from samples collected from the Pacific coast of Japan.
Characteristics and morphology
Plesiocystis pacifica cells are straight, rod-shaped, and have blunt ends. Like other myxobacteria, groups of cells can form round fruiting bodies. The species is an obligate aerobe and a chemoorganotroph. Cells are motile and move by gliding. The species is mesophilic and grew best under laboratory conditions in a temperature range of 15-32C, a neutral to slightly basic pH, and salinity similar to that of seawater (making it slightly halophilic). P. pacifica cells require sodium to grow, as expected for marine bacteria.
Taxonomy
Plesiocystis pacifica is the type species and only member of the genus Plesiocystis, both first described in the same 2003 study.
“Plesiocystis pacifica” enters the record as species of Deltaproteobacteria. Crown Archives preserves that source wording while asking what Plesiocystis, pacifica and species can confirm, complicate or overturn.
Why this record matters
“Plesiocystis pacifica” is worth following because a concise public description often conceals a longer documentary argument. Here, Plesiocystis, pacifica and species provides the most credible route into that argument.
Stable identifiers, scientific names and standards terminology offer the best bridge between this overview and specialist evidence. The source revision retrieved here is dated Jun 24, 2026. The linked authority identifier is Q26271219. None of the 0 selected statements returned an explicit reference. The first chronological checks are 2003.
Current terminology should not be projected backward without checking the classification used when the underlying evidence was created. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
How to read it
Check terminology, classification and the date of the cited evidence. Scientific names and technical consensus can change while older records retain historical value.
