Fig. 2From: The microbiota in bronchoalveolar lavage from young children with chronic lung disease includes taxa present in both the oropharynx and nasopharynxBacterial load in DNA extracted from clinical specimens. Bacterial load is expressed on a log-scale as genome equivalents (GE)/μL extracted DNA. The red dashed line indicates 1 × 103 GE/μL of the extracted DNA. The black dotted line indicates the qPCR limit of detection (90 GE). Quantification below the qPCR limit of detection (90 GE) is unreliable. NP NP swab, OP OP swabBack to article page
