Number (and percentage) of GBS transcripts significantly up- and down-regulated in donor A and the seven other donor blood samples according to the duration of the incubation at 37°C.

An ORF is considered differentially expressed if there is a significant (P<0.05, T-test) change in expression greater than 2-fold at one time point relative to another, and if the signal is detected. Up- and down-regulation are expressed relative to time 0.
aPercentage is expressed relative to the number of genes whose expression is modified.
bPercentage is expressed relative to the total number of genes present on the chip.
