Erratum

Upon publication of the original manuscript [1] it was highlighted that errors had been introduced during the revision process. These errors affect the first column of Table 3. The presentation of the antigenic structures within the first column had been formatted such that they were not clear and were misleading to the reader.

These errors change neither the outcome of the experiments nor the conclusions of the article; and have since been corrected in the original manuscript [1] and acknowledged in this erratum.

The corrected table is shown below:

Table 3 Re-classification of Citrobacter strains in serogroups O3 and O8

The publisher also acknowledges and apologizes for these errors.
