The phenotypic and molecular resistance induced by a single-exposure to sub-mutant prevention concentration of marbofloxacin in Salmonella Typhimurium isolates from swine.

Abstract excerpt

In the present study, the molecular mechanisms of antibiotic resistance in Salmonella Typhimurium clinical isolates from pigs were investigated using a single-step mutation model of exposure to sub-mutant prevention concentrations (MPCs) of marbofloxacin. The minimum inhibitory concentrations (MICs) of seven antibacterial drugs were evaluated against 30 S. Typhimurium clinical isolates from different pigs. MPCs...
