Abstract
ABSTRACTThe Latin American Coalition for Escherichia coli Research (LACER) was created as a network of investigators using One Health approaches trying to understand infections caused by regional E. coli isolates and to sound the alarm due to the evolution of strains that are multiresistant to antibiotics (resistome) that also display different virulence profiles (virulome). After the COVID19 pandemic, a major concern by investigators has been the appearance of more virulent and resistant strains. Recently, a paper published in Microbiology Spectrum by Brazilian investigators (Fuga B., et al. Microbiol Spectr 10:e0125621, 2022, https://doi.org/10.1128/spectrum.01256-21) has used a genomic approach to demonstrate that during a period of 45 years, a wide resistome and virulome has converged, resulting in the appearance and persistence of high-risk clones affecting humans, animals and the environment, and its rapid dissemination is becoming an unattended international threat.
