説話・伝承の生成--変容の場としての唱導および直談 (説話・伝承学の可能性)

Abstract

Insertion mutagenesis using TnphoA has proved to be a potent device for the creation of easily screened knockout mutations in genes encoding virulence determinants in a variety of pathogenic bacteria. Initial identification of genes with TnphoA directly initiates more sophisticated genetic and biochemical studies on these factors essential to our understanding of bacterial pathogenesis.
