Fig. 1From: Comparison of placenta samples with contamination controls does not provide evidence for a distinct placenta microbiotaQuantitative PCR analysis of 16S rRNA gene copy numbers. 16S rRNA gene copies per reaction were quantified in the six study subjects using (a) PSP extraction method and (b) MO BIO extraction method. Fetal side (FS), maternal side (MS). c, d Comparison of mean cycle threshold values for 16S rRNA gene qPCR. Limit of detection is 38.29 (PSP) and 34.04 (MO BIO). All data sets were analyzed by Kruskal-Wallis with Dunn’s post test. Comparison of any pair of placental samples to controls yielded p > 0.05Back to article page
