Lelliottia

Lelliottia is a genus of Gram-negative, facultatively anaerobic, rod-shaped bacteria belonging to the family Enterobacteriaceae. It was proposed in 2013 after multilocus sequence analysis (MLSA) demonstrated that several species previously classified in the genus Enterobacter formed distinct evolutionary lineages. The type species is Lelliottia nimipressuralis.^[1]

Etymology

The genus is named in honor of British bacteriologist R.A. Lelliott for his contributions to bacterial taxonomy and identification, particularly within the Enterobacteriaceae.^[1]

Taxonomy

The genus Lelliottia was established following the reclassification of two species, Enterobacter nimipressuralis and Enterobacter amnigenus, into this new genus. Subsequent research has expanded the genus, adding additional species through isolation and genomic analyses.

Characteristics

Members of the genus Lelliottia are facultatively anaerobic, Gram-negative rods capable of fermenting various carbohydrates. These bacteria grow readily on standard laboratory media and share general biochemical characteristics with other members of the Enterobacteriaceae. They have been isolated from diverse environments, including clinical specimens, food sources, and various environmental niches.

Species

Currently recognized species within the genus Lelliottia include:

• Lelliottia amnigena (Basonym: Enterobacter amnigenus)
• Lelliottia jeotgali
• Lelliottia nimipressuralis (type species; basonym: Enterobacter nimipressuralis)
• Lelliottia wanjuensis
