Abstract: The use of antimicrobials in aquaculture is increasingly being scrutinized. In Chile, piscirickettsiosis accounts for approximately 90% of the total volume of antibiotics used in marine aquaculture. Treatment failures are frequently reported, but there is… read more here.

Published in 2023 at "Molecular Biology and Evolution"

DOI: 10.1093/molbev/msad010

Abstract: Abstract Experimental evolution studies have shown that weak antibiotic selective pressures (i.e., when the antibiotic concentrations are far below the minimum inhibitory concentration, MIC) can select resistant mutants, raising several unanswered questions. First, what are… read more here.

Published in 2023 at "Applied and Environmental Microbiology"

DOI: 10.1128/aem.00261-23

Abstract: It is generally assumed that a natural function of antibiotics is to provide their producers with a competitive advantage. If this were the case, sensitive organisms in proximity to producers would be exposed to inhibitory… read more here.

Published in 2021 at "mSphere"

DOI: 10.1128/msphere.00108-21

Abstract: Very low antibiotic concentrations have been shown to drive the evolution of antimicrobial resistance. While substantial progress has been made to understand the driving role of low concentrations during resistance development for different antimicrobial classes,… read more here.
