Remarks: BACKGROUND: Enterobacter sakazakii is an opportunistic pathogen that can cause infections such as necrotizing enterocolitis, bacteraemia, meningitis and brain abscess/lesions. When the species was defined in 1980, 15 biogroups were described and it was suggested that these could represent multiple species. In this study the taxonomic relationship of strains described as E. sakazakii was further investigated. RESULTS: Strains identified as E. sakazakii were divided into separate groups on the basis of f-AFLP fingerprints, ribopatterns and full-length 16S rRNA gene sequences. DNA-DNA hybridizations revealed five genomospecies. The phenotypic profiles of the genomospecies were determined and biochemical markers identified. CONCLUSION: This study clarifies the taxonomy of E. sakazakii and proposes a reclassification of these organisms.

Note:

The Culture Collections hold cell cultures, bacteria, fungi and virus strains from worldwide sources. Our scientists ensure that the identification of the cultures is correct and they remain unchanged from when they are first deposited with the Collection. Nevertheless, some of the data we provide about the cultures is supplied by the person depositing the strains and, although we have multiple checking procedures in place, we cannot always verify all their data. Please note that the Culture Collections cannot be held responsible for any inaccuracies in the data provided by the depositors.

Cultures supplied by Culture Collections are to be used as controls for microbiology testing and for research purposes only. Please view the Terms & Conditions of Supply for more information.

Contact us if you want to discuss commercial use of the cultures.
