Figure 2: Repression by Pseudomonas strains of pathogenicity- and virulence-associated gene expression in S. scabies. In plate inhibition assays, S. scabies was either grown in the absence of an antagonist or was confronted with a Pseudomonas strain (LBUM 223, LBUM 300 or LBUM 647). Transcripts of genes txtA (A), txtC (B), nec1 (C) and tomA (D) were quantifi ed in the pathogen after 6 days using quantitative RT-PCR assays. Data are presented as mean ± standard error (n = 9). Means of groups annotated with different letters were signifi cantly different (P < 0.05).
