Fig. (3c) Dendrogram based on DGGE profiles representing 16S rRNA gene PCR-derived amplicons of BAL samples collected from eleven-week-old female BALB/cj mice. The light-blue (O) groups received oral exposure to Vancomycin from drinking water ad libitum. The red (IN) received vancomycin 0.21 mg/35µl nasally by i.n. 2x5 days. The blue PBS group received PBS 35µl nasally by i.n. 2x5 days. All IN Vancomycin exposed except one sample cluster together. Reliably separated branches on the dendrogram have a high (green) cophenetic score.
