As all strains of A. vitis tested were sensitive to TFX both in this work and in a previous study [ 12 ] , experiments were conducted to determine the effectiveness of a TFX-producing, avirulent strain of A. vitis in the prevention of crown gall caused a three strains of A. vitis.
I have demonstrated that a gene coding for a bifunctional catalase-peroxidase is likely a transfer from archaea to a variety of pathogenic bacteria, including E. coli O157:H7 [ 9 ] . Although not yet directly implicated in O157:H7 as a virulence factor, this enzyme has been implicated as a virulence factor in Mycobacterium tuberculosis [ 24 26 ] , and in Legionella pneumophila [ 25 ] . Furthermore, this E. coli O157:H7 catalase-peroxidase has been associated with enterohaemorrhagic hemolysin in a variety of shiga-like toxin-producing (verotoxin-producing) E. coli [ 30 31 ] . This correlation of the presence of the catalase-peroxidase in many virulent but not in avirulent strains suggests a direct role in the virulence of enterohemorrhagic E. coli .
Thus, the CFU ratios were approximately 10:1, and 1:1 or 1:10 avirulent:tumorigenic strain.
Induction of SAR has been reported to be dependent upon the NPR1 gene [ 9 10 11 ] . In these studies, neither SA/SA analogs nor avirulent bacteria were able to induce SAR on npr1 mutant plants.
Our results are in broad agreement with these studies with respect to the central role of NFκB in response to infection, but are also puzzling because we would not expect intestinal cells to respond so strongly to the presence of avirulent or heat-killed bacteria, even when presented on the apical surface of a confluent, polarized monolayer, regardless of the presence or absence of serum.
