Bacterial names are continually being changed in order to more adequately describe natural
groups (the units of microbial diversity) and their relationships. The problems in Klebsiella …

A new Klebsiella species, K. variicola, is proposed on the basis of total DNA-DNA
hybridization, on the monophyly observed in the phylogenetic analysis derived from the …

We investigated the diversity of the chromosomal class A beta-lactamase gene in Klebsiella
pneumoniae in order to study the evolution of the gene. A 789-bp portion was sequenced in …

Klebsiella oxytoca causes opportunistic human infections and post-antibiotic haemorrhagic
diarrhea. This Enterobacteriaceae species is genetically heterogeneous and is currently …

The diversity and evolution of the class A OXY β-lactamase from Klebsiella oxytoca were
investigated and compared to housekeeping gene diversity. The entire bla OXY coding …

Phylogenetic relations within the family Enterobacteriaceae were analyzed using partial
dnaJ sequences of 165 strains belonging to 93 species from 27 enterobacterial genera. The …

Strains previously identified as Klebsiella oxytoca phylogroup Ko6 were characterized by
rpoB, gyrA and rrs gene sequencing, genome-sequence based average nucleotide identity …

Enterobacterial strains of Raoultella spp. display a penicillinase-related β-lactam resistance
pattern suggesting the presence of a chromosomal bla gene. From whole-cell DNA of …

Raoultella spp. have recently been separated from the genus Klebsiella based on their
molecular characteristics. It was discovered that Raoultella ornithinolytica can be …

A surface water isolate of Raoultella sp. having both multidrug-and multimetal-resistant
ability was isolated and identified as Raoultella planticola. R. planticola displayed resistance …
