Number (and percentage) of GBS transcripts significantly up- and down-regulated according to the temperature and duration of incubation in human blood.

An ORF was considered to be differentially expressed if there was a “present” signal, if there was a significant (P<0.05, T-test) change in expression greater than 2-fold at one time point relative to another and if these criteria were met for at least six of the seven donor samples. Up- and down-regulation are expressed relatively to time 0.
Percentage are expressed relative to the 1,995 ORFs present on the chip.
