Sub-inhibitory concentrations of antibiotics and wastewater influencing biofilm formation and gene expression of multi-resistant Pseudomonas aeruginosa wastewater isolates.

Abstract excerpt

Sub-inhibitory concentrations of antibiotics, which are found in environmental water systems and sewage plants due to an increased use in therapeutical and preventive fields, influence bacterial behavior in biofilms. The application of sulfamethoxazole, erythromycin, and roxithromycin induced changes in biofilm dynamics regarding biomass formation, spatial structure and specific gene expression in different...
