Corrigendum: Comprehensive Molecular Characterization of Escherichia coli Isolates from Urine Samples of Hospitalized Patients in Rio de Janeiro, Brazil

In the original article, there was a mistake in Table 2 and Supplementary Data Sheet 1, S.6 as published. The virotype of the isolate 4233 is not typeable. The corrected Table 2 and Supplementary Data Sheet 1, S.6 appear below.

In the original article, there was an error in the presented percentage of the virotype D among ST131 isolates.

A correction has been made to Results, Escherichia coli ST131, Paragraph 1

UPEC strains produce different adhesins and fimbriae, including type 1 fimbriae. The FimH protein is the adhesive subunit of type 1 fimbriae that is used for epidemiological typing of UPEC. In this study, three fimH types were identified among the ST131 isolates, two O25:H4/ST131 isolates belonged to fimH22, two O16:H5/ST131 isolates to fimH41 while the majority of O25:H4/ST131 isolates (n = 22) belonged to fimH30 (Table 2). The virulence genes (afa/draBC, iroN, sat, ibeA, papGII, papGIII, cnf-1, hlyA, cdtB, neuC-K1, kpsMIIK2, kpsmII-K5) were used to determine the virotype of ST131 isolates based on the virulence profile. O25:H4/ST131 isolates belonged to different virotypes, i.e., 7 (26.92%) to virotype A, 1 (3.84%) to virotype B, 14 (53.84%) to virotype C, and 3 (11.53%) to virotype D. Isolates belonging to virotype C could be divided into subtypes C2 (n = 6) or C3 (n = 3), whereas five isolates could not be further subtyped. The only two isolates with serotype O16:H5/ST131 were classified as virotype A (see Data Sheet S6). Almost all O25:H4/ST131 isolates were resistant to fluoroquinolones, whereas the O16:H5/ST131 isolates were susceptible to this antibiotic. The bla_CTX−M gene was most prevalent in O25:H4/ST131 fimH30 fluoroquinolones resistant (O25:H4/ST131-H30-R) isolates belonging to virotype C. Within ST131, bla_CTX−M15 was confined to the H30-R sub-clone known as O25:H4/ST131-H30-Rx, represented by 9 (34.61%) isolates (Table 2).

The authors apologize for these errors and state that this does not change the scientific conclusions of the article in any way. The original article has been updated.
