Emergence and genomic chion of Proteus mirabilis harboring blaNDM-1 in Korean companion dogs

AbstractProteus mirabilis is a commensal bacterium dwelling in the gastrointestinal (GI) tract of humans and animals. Although New Delhi metallo- β-lactamase 1 (NDM-1) producingP. mirabilis is emerging as a threat, its epidemiology in our society remains largely unknown. LHPm1, the firstP. mirabilis isolate harboring NDM-1, was detected from a companion dog that resides with a human owner. The whole-genome study revealed 20 different antimicrobial resistance (AMR) genes against various classes of antimicrobial agents, which corresponded to the MIC results. Genomic regions, including MDR genes, were identified with multiple variations and visualized in a comparative manner. In the whole-genome epidemiological analysis, multiple phylogroups were identified, revealing the genetic relationship of LHPm1 with otherP. mirabilis strains carrying various AMR genes. These genetic findings offer comprehensive insights into NDM-1-producingP. mirabilis, underscoring the need for urgent control measures and surveillance programs using a “one health approach”.
