Key Points

To explore the spread of extended-spectrum β-lactamase-producing Enterobacterales in community living spaces and assess the influence of housing density.
Conducted a geographic analysis of ESBL-E colonization in humans and animals.
Performed genomic analysis to investigate strain diversity and potential dissemination.
Significant colonization of ESBL-E observed in both humans and animals.
Geographic analysis suggests human impact on animal colonization without direct transmission.
Genomic findings indicate potential for ESBL-E dissemination over large distances.

Implication

This analysis finds significant colonization of ESBL-E in humans and animals, indicating housing density impacts.

Abstract

In the area under study, there is significant colonization of both human and animals by ESBL-E, and a major diversity among the isolated strains. Our geographic analysis suggests a human impact on animal colonization, even though the results do not support direct transmission. Concurrently, genomic analysis suggests the possibility of dissemination over significant distances.
