Revisiting the taxonomy of the genus Elizabethkingia using whole-genome sequencing, optical mapping, and MALDI-TOF, along with proposal of three novel Elizabethkingia species: Elizabethkingia bruuniana sp. nov., Elizabethkingia ursingii sp. nov., and Elizabethkingia occulta sp. nov
The genus Elizabethkingia is genetically heterogeneous, and the phenotypic similarities between recognized species pose challenges in correct identification of clinically derived isolates. In addition to the type species Elizabethkingia meningoseptica , and more recently proposed Elizabethkingia mir...

Summary: | The genus
Elizabethkingia
is genetically heterogeneous, and the phenotypic similarities between recognized species pose challenges in correct identification of clinically derived isolates. In addition to the type species
Elizabethkingia meningoseptica
, and more recently proposed
Elizabethkingia miricola
,
Elizabethkingia anophelis
and
Elizabethkingia endophytica
, four genomospecies have long been recognized. By comparing historic DNA–DNA hybridization results with whole genome sequences, optical maps, and MALDI-TOF mass spectra on a large and diverse set of strains, we propose a comprehensive taxonomic revision of this genus. Genomospecies 1 and 2 contain the type strains
E. anophelis
and
E. miricola
, respectively. Genomospecies 3 and 4 are herein proposed as novel species named as
Elizabethkingia bruuniana
sp. nov. (type strain, G0146
T
= DSM 2975
T
= CCUG 69503
T
= CIP 111191
T
) and
Elizabethkingia ursingii
sp. nov. (type strain, G4122
T
= DSM 2974
T
= CCUG 69496
T
= CIP 111192
T
), respectively. Finally, the new species
Elizabethkingia occulta
sp. nov. (type strain G4070
T
= DSM 2976
T
= CCUG 69505
T
= CIP 111193
T
), is proposed. |
