From: Knockout of alanine racemase gene attenuates the pathogenicity of Aeromonas hydrophila
Expression studies by quantitative real-time PCR: relative transcript profiles 13 virulence-related genes of A. hydrophila. 16S rRNA was used as the internal control for normalization the relative expression folds of individual transcripts. Results are mean of at least three independent experiments and the standard deviation (SD) is indicated by the error bars. Significance analysis was done by Student’s t-test, *P < 0.05, **P < 0.01
