Pluralibacter pyrinus
species of Gammaproteobacteria
Pluralibacter pyrinus (formerly Enterobacter pyrinus) is a Gram-negative, motile, facultatively-anaerobic, rod-shaped bacterium. P. pyrinus is the causitive agent of brown leaf spot disease of pear trees.
Background
The cause of brown leaf spot disease affecting pear trees in South Korea was first identified as a novel bacterial infection in 1990. The proposed name for the species was Erwinia pirina, but this name was not validly published. In 1993, further research grouped the organism in the genus Enterobacter as E. pyrinus. Later studies of the genus Enterobacter lead to the species being reclassified into the novel genus Pluralibacter in 2013. The species name is derived from the Greek word pŷr, which means pear.
“Pluralibacter pyrinus” enters the record as species of Gammaproteobacteria. Crown Archives preserves that source wording while asking what Pluralibacter, pyrinus and species can confirm, complicate or overturn.
Why this record matters
“Pluralibacter pyrinus” is worth following because a concise public description often conceals a longer documentary argument. Here, Pluralibacter, pyrinus 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 May 26, 2025. The linked authority identifier is Q26271228. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1990, 1993 and 2013.
Current terminology should not be projected backward without checking the classification used when the underlying evidence was created. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
