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 ...

Development of resistance during antimicrobial therapy caused by insertion sequence interruption of porin genes
(American Society for Microbiology, 1999-01-01)
We have demonstrated by using an in vitro approach that interruption of the OmpK36 porin gene by insertion sequences (ISs) is a common type of mutation that causes loss of porin expression and increased resistance to ...
