Transcription changes in the A. pleuropneumoniae lip40 gene under different conditions. Relative expression of the lip40 gene during stimulation with 42 °C, anaerobic conditions, or 16 °C was normalized to that of lip40 expressed under normal culture conditions. The fold changes in lip40 expression are shown. Error bars indicate standard errors. Double asterisks indicate P < 0.01, calculated with Student’s t test
