ABSTRACT

Fifty-one Rahnella aquatilis and R. aquatilis-like strains from water, snails and human sources were characterized by routine biochemical tests, carbon source utilization tests, DNA relatedness (hydroxyapatite method) and 16S rRNA sequencing. The results of the genetic methods indicated that the strains comprised three closely related species within the genus Rahnella. It was not possible to differentiate R. aquatilis from the two newly recognized species. The new species were therefore given the vernacular names Rahnella genomospecies 2 and Rahnella genomospecies 3.

Key Words: Rahnella aquatilis • Rahnella aquatilis-like strains • Rahnella genomospecies • taxonomy • DNA relatedness

The GenBank accession numbers for the sequences reported in this paper are U88434-U88439, U90757 and U90758.
