AbstractKlebsiella oxytocacauses opportunistic human infections and post-antibiotic haemorrhagic diarrhoea. ThisEnterobacteriaceaespecies is genetically heterogeneous and is currently subdivided into seven phylogroups (Ko1 to Ko4, Ko6 to Ko8). Here we investigated the taxonomic status of phylogroups Ko3 and Ko4. Genomic sequence-based phylogenetic analyses demonstrate that Ko3 and Ko4 formed well-defined sequence clusters related to, but distinct from,Klebsiella michiganensis(Ko1),Klebsiella oxytoca(Ko2),K. huaxiensis(Ko8) andK. grimontii(Ko6). The average nucleotide identity of Ko3 and Ko4 were 90.7% withK. huaxiensisand 95.5% withK. grimontii, respectively. In addition, three strains ofK.…

Corrigendum: Phylogeny of Vibrio vulnificus From the Analysis of the Core-Genome: Implications for Intra-Species Taxonomy

2018

Vibrio vulnificus (Vv) is a multi-host pathogenic species currently subdivided into three biotypes (Bts). The three Bts are human-pathogens, but only Bt2 is also a fish-pathogen, an ability that is conferred by a transferable virulence-plasmid (pVvbt2). Here we present a phylogenomic analysis from the core genome of 80 Vv strains belonging to the three Bts recovered from a wide range of geographical and ecological sources. We have identified five well-supported phylogenetic groups or lineages (L). LI comprises a mixture of clinical and environmental Bt1 strains, most of them involved in human clinical cases related to raw seafood ingestion. LII is linked to the aquaculture industry and incl…
