Energy-dependent accumulation of norfloxacin and porin expression in clinical isolates of Klebsiella pneumoniae and relationship to extended-spectrum β-lactamase production
(American Society for Microbiology, 2002-12-01)
The relationships between porin deficiency, active efflux of fluoroquinolones, and extended-spectrum β-lactamase (ESBL) production were determined for 53 clinical isolates of Klebsiella pneumoniae. Thirty-two ESBL-positive ...

Identification and characterization of a new porin gene of Klebsiella pneumoniae: Its role in β-lactam antibiotic resistance
(American Society for Microbiology, 1999)
Klebsiella pneumoniae porin genes were analyzed to detect mutations accounting for the porin deficiency observed in many β-lactam-resistant strains. PCR and Southern blot analysis revealed the existence of a third porin ...

Role of Klebsiella pneumoniae LamB porin in antimicrobial resistance
(American Society for Microbiology, 2003-10-01)
To investigate the contribution of LamB in Klebsiella pneumoniae antimicrobial resistance, we determined the MICs of various antibiotics and the frequency of mutation to increased cefoxitin or meropenem resistance of the ...
