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.^[4][1] In 1993, further research grouped the organism in the genus Enterobacter as E. pyrinus.^[1] Later studies of the genus Enterobacter lead to the species being reclassified into the novel genus Pluralibacter in 2013.^[2] The species name is derived from the Greek word pŷr, which means pear.^[1]
