 A Corrigendum on Molecular Epidemiology and Characteristics of CTX-M-55 Extended-Spectrum β-Lactamase-Producing Escherichia coli From Guangzhou, China by Zeng, S., Luo, J., Chen, X., Huang, L., Wu, A., Zhuo, C., and Li, X. (2021). Front. Microbiol. 12:730012. doi: 10.3389/fmicb.2021.730012 CTX-M-55 IncI1 plasmid ISEcp1 ST1193 E. coli IncFII plasmid

The author order was incorrectly listed as “Shihan Zeng, Jiajun Luo, Xiaoyan Li, Chao Zhuo, Aiwu Wu, Xiankai Chen and LiShao Huang”. The correct order is “Shihan Zeng, Jiajun Luo, Xiankai Chen, LiShao Huang, Aiwu Wu, Chao Zhuo, Xiaoyan Li2”. The author list and the correspondence section have been updated.

In the original article, there was an error. The sentence “There were only three single nucleotide differences between them.” is irrelevant.

A correction has been made to Results, Genetic Environment Surrounding the blaCTX−M−55 Gene, paragraph one:

“The genetic environment surrounding the blaCTX−M−55 gene is presented in Figure 6. Five structures were obtained by analyzing mobile elements around the blaCTX−M−55 gene and named type I to V. The mobile elements located upstream of blaCTX−M−55 mainly included ISEcp1 (complete or incomplete) and IS26. Downstream of the blaCTX−M−55 genes ORF477 was consistently found. Among them, type II “ISEcp1-blaCTX−M−55-ORF477” was the predominant (63.16%, 60/95) genetic environment of the blaCTX−M−55 gene and plasmids containing this structure included IncI1, IncFIB, IncFIC, IncFII, IncHI2, and IncI2 (Figure 6). Likewise, the genetic environment of the blaCTX−M−55 gene on the chromosome (12/13) was almost type II, the other is type I. Compared with type II, only a large deletion (489 to 1140 bp) of ISEcp1 was found in type I. Moreover, the blaCTX−M−55 genes of isolate 75, 128, and 173 were found on both the chromosome and the IncI1 plasmid, and both of the genetic environments between them belong to type II. The blaCTX−M−55 gene of isolate N18 was found on both the chromosome and the IncFIC plasmid, among which the genetic environment on the chromosome was type II, and that on the IncFIC plasmid was type III “IS26-ΔISEcp1-blaCTX−M−55-ORF477.” The occurrence of the type III structure was similar to that of the type II structure, but ISEcp1 of the type III structure was disrupted by IS26. Interestingly, IS26 mainly emerged upstream of the blaCTX−M−55 gene in the IncFIC and IncFII plasmids. Type IV “IS26-blaCTX−M−55-ORF477” mainly exists in IncFII plasmids (15/17).”
