FIG. 4.
Quantification of the transcript levels of the blaOXA-66 genes from different clinical strains of A. baumannii (ISAB ab3, ab1308, ab1316, and ab1254; IIAB ab1297; and IRAB ab1266, abh9, abh11, abh17, and abh37). (A) RT-PCR analysis of mRNA expression. (B) Relative expression (n-fold) determined from data in A. (C) Relative expression (n-fold) determined by real-time RT-PCR. The relative expression (n-fold) was measured against the expression level of ISAB strain ab3. The expression of the 16S rRNA gene was used as the internal control. Each bar represents the average value of three independent experiments, and the error bars represent the standard deviations.
