First report and genomic characterization of Escherichia coli O111:H12 serotype from raw mussels in Turkiye.

ABSTRACT:

Background

This study aimed to assess the prevalence and genomic characteristics of Shiga-toxigenic (STEC) and Enteroaggregative E. coli (EAEC) strains in raw mussels and ready-to-eat (RTE)-stuffed mussels, focusing on potential public health implications for identifying virulence and antimicrobial resistance genes.

Results

The genome sequence analysis identified the E. coli strain named 23EM as serotype O111:H12, with adhesion (fimH-54) and fumarate hydratase (fumC-11) genes. The draft genome (4.9 Mb, 50.6% GC content, 111 contigs, 4,688 genes) is available in NCBI GenBank (accession JAWXVJ000000000). The strain, classified as ST292 and CC ST10, showed high similarity to nonpathogenic E. coli MG1655 but was distinct from pathogenic strains such as EAEC and ExPEC. In silico
