The relative abundance of predominant bacteria in zebrafish intestine. A: The mean richness of DGGE bands from the control samples collected at 4, 6 and 8 dpf. B: The mean richness of DGGE bands from the samples exposed to different TNBS concentrations (0, 25, 50 and 75 μg/ml) collected at 8 dpf. The staining intensity of fragments was expressed as a proportion (%) of the sum of all fragments in the same lane. Rf, relative front.
