Protective effect of AhMtk13a phage on zebrafish infected with A. hydrophila 3-10. Survival and death rates (%) in different experimental groups: Group I—fish injected with A. hydrophila GW3-10, placed in the aquaria with the same bacteria added and immediately treated with the phage; Group II (bacterial control)—fish injected with the A. hydrophila GW3-10 and kept in the aquaria containing the same bacterial pathogen; Group III (phage control)—fish injected with saline and placed in the aquaria containing the AhMtk13a phage only; Group IV (vehicle control)—fish received saline only through intraperitoneal injection. Neither phage nor bacteria were added to these aquaria. The results are the averages of three parallel experiments with SD shown as the vertical lines.
