Quantification of bacterial abundances using fluorescent in situ hybridization. Select fecal samples from CDI set 1 were profiled using class specific DNA probes as shown. (A) A comparison of class relative abundances measured by Microbiota Array and by FISH. (B) Representative captured image from each sample visualized with Proteobacteria fluorescent probe (green color) and DAPI DNA stain (blue color).
