Figure 2. Specific bacterial members of the zebrafish microbiota are sufficient to rescue normal expansion of the GF β cell mass. ; (A) Experimental timeline for all subsequent zebrafish experiments, unless stated otherwise.Experimental manipulations are denoted by red text. Important zebrafish developmental events are denoted by black text. (B) Quantification of β cells in CV, GF and GF larvae treated at 4 dpf with either non-sterile tank water (XGF) or mono-associated with a specific bacterial strain. Bacterial mono-associations are labeled by genus. Different Aeromonas sp are labeled with a number (1, 2 or 3). *p
