The video demonstrates the phage therapy technique targeting Pseudomonas aeruginosa infection in cystic fibrosis zebrafish embryos. Phage therapy effectively diminishes bacterial load and mitigates proinflammatory immune responses in CF zebrafish embryos infected with bacteria, leading to reduced CF embryo lethality.
Protocol
1. Microinjection of zebrafish embryos with bacteria and phage cocktail NOTE: To perform a systemic infection, the embryo must have blood circulation that usually starts after 26 hpf. After 26 hpf, dechorionate embryos with pronase solution prepared by dissolving pronase powder in E3 medium at a concentration of 2 mg/mL. Gently pipette the embryos to break the chorion. Discard the pronase/E3 medium and rinse the dish several times with fresh E3 to …
