Source: Bernut, A., et al., Deciphering and Imaging Pathogenesis and Cording of Mycobacterium abscessus in Zebrafish Embryos. J. Vis. Exp. (2015).This video demonstrates a protocol for isolating and quantifying Mycobacterium abscessus from an infected zebrafish embryo. The procedure involves embryo euthanasia, tissue lysis, and homogenization to release the bacteria, followed by centrifugation and resuspension in a surfactant buffer. Finally, the bacterial suspension is serially diluted, plated on antibiotic-supplemented agar, and incubated to enable colony formation and quantification.
