Wastewater and colloidal extracts of wastewater-irrigated soils select for resistant Acinetobacter baylyi beyond what measured antibiotic concentrations predict

Katharina Axtmann, Christina Paffenholz, Alina Auerhammer…·Gabriele Bierbaum

The paper shows that wastewater and colloidal soil extracts select for antibiotic-resistant Acinetobacter baylyi despite low antibiotic concentrations, suggesting complex contaminant mixtures drive resistance.

Reduced antibiotic effect of ciprofloxacin on bacteria in the presence of montmorillonite

Katharina Axtmann, Benjamin Justus Heyde, Silas Brinkmann…·Gabriele Bierbaum

This study shows that montmorillonite reduces but does not eliminate ciprofloxacin's growth-inhibitory effect on bacteria in soil environments.
