Abstract excerpt
Eight multi-drug resistant mutants (4.94%) were found in 162 clinical isolates of P. aeruginosa after exposure to norfloxacin at different concentrations (1/4, 1/2, 1, 2 and 4 MICs) and were investigated for the mechanisms of drug resistance. All the mutants were eight-times more resistant to norfloxacin than the respective parents, and showed the cross-resistance to the other fluoroquinolones. However, these...
