Figure 5.
(A) Log∆∆Ct values of Serratia spp. in samples obtained from Group 1 neonates (that had positive cultures) compared to those obtained from Group 2 neonates (culture-negative neonates). (B) Log∆∆Ct values of Serratia spp. in the first swab collected from each neonate of Group 1 compared to the last swab collected. Log∆∆Ct values of 0 represent 100% of the bacterial population, −1 is 10%, −2 is 1%, and so on until −6 (0.0001%), which is the detection limit. The “*” indicates statistical significance (p < 0.05).
