    ..In addition, among the extracellular products, those which have cytotoxic activity to Vero cells may contribute to the lethality in sepsis caused by S. aureus in this murine model. ..

    ..These findings indicate that AZM, EM, RXM, and RKM each has an inhibitory effect on exoenzyme production separate from the antimicrobial effect and that, of these macrolides, AZM has the strongest virulence-suppressing effect. ..

    ..Thus, the horizontal gene transfer and the genomic rearrangement were proven to have played an important role in the pathogenic differentiation and diversification of P. syringae...
