Rahnella aquatilis

Description and significance

Rahnella aquatilis is a relatively rare gram-negative rod-shaped bacteria which has been found in fresh water, soil, certain animals such as snails [5] and certain beetles, [4] and isolated human clinical specimens. [2] This bacterium is of importance because of its abundance and its disease-causing ability in humans. Many different strains have been isolated, and presumably more will be disocvered.

Genome structure

As of the year 2000, at least 70 strains of Rahnella aquatilis have been identified [1]. According to the National Center for Biotechnology Information (NCBI), the whole genome has been sequenced for R. aquatilis Strain Y9602. This particular strain has a genome consisting of 4,864,217 basepairs, with two identified plasmids [2]. Another strain, Rahnella aquatilis CUETM 77-115, was shown to have a genome consisting of 5,440,269 basepairs, and had a G-C content of 52.1% [3].
