The authors wish to correct the following errors in the published article.
In the Results section, under “WGS data quality and pre-processing”, the sentence:
“Four isolates from parent stock faeces from batch 2 were included for WGS were identified by the MALDI-TOF MS as E. fergusonii, a closely related species to E. coli.” should read:
“Four isolates from parent stock faeces from batch 4 were included for WGS were identified by the MALDI-TOF MS as E. fergusonii, a closely related species to E. coli.”
In the caption of Table 4, the text:
“Genetic background of fluoroquinolone resistance in E. coli through WGS, given per origin isolate (PS = Parent stock; EN = environment hatchery; DC = day-old chicks).” should read:
“Genetic background of fluoroquinolone resistance in E. coli and E. fergusonii through WGS, given per origin isolate (PS = Parent stock; EN = environment hatchery; DC = day-old chicks).”
In addition, Figure 2 contained incorrect annotations for the variable “origin”. The published figure should be replaced with the corrected version provided below.
The authors apologize for these errors and any inconvenience caused they may have caused. These corrections do not affect the results or conclusions of the article.
