Whole-Genome Sequences of Two Chloramphenicol-Florfenicol Resistance Gene-Carrying Enterococcus faecalis Isolates ES-3-1 and ES-11 from Pig Stools in South Korea

초록

We report the complete genome sequences of cfr(D)-positive Enterococcus faecalis strains, ES-3-1 and ES-11, which were isolated from pig stools in 2021. The assembled genomes revealed that cfr(D) was located in the Inc18 type plasmids: a 21,899 bp plasmid of ES-3-1 and a 15,026 bp plasmid of ES-11. The IS1216 mobile elements were found to frank the cfr(D) locus on these two plasmids, and fexA and poxtA2 genes co-existed with cfr(D). Both ES-3-1 and ES-11 strains belonged to sequence type 16, which has animal and human origins, suggesting the high possibility of cfr(D) transmission between animals and humans. © 2024, The Korean Society for Microbiology and Biotechnology.
