Instability of pathogenicity islands in uropathogenic Escherichia coli 536.

abstract：:Porphyromonas gingivalis, an obligate anaerobe, exhibits a relatively high degree of aerotolerance and possesses superoxide dismutase (SOD) which is induced by exposure to air. To clarify roles for SOD in this organism, the gene encoding SOD (sod) on the P. gingivalis chromosome was disrupted in a gene-directed way by...
