Abstract
Vertebrates are colonized at birth by complex and dynamic communities of microorganisms that can contribute significantly to host health and disease. The ability to raise animals in the absence of microorganisms has been a powerful tool for elucidating the relationships between animal hosts and their microbial residents. The optical transparency of the developing zebrafish and relative ease of generating germ-free (GF) zebrafish make it an attractive model organism for gnotobiotic research. Here we provide a protocol for generating zebrafish embryos; deriving and rearing GF zebrafish; and colonizing zebrafish with microorganisms. Using these methods, we typically obtain 80-90% sterility rates in our GF derivations with 90% survival in GF animals and 50-90% survival in colonized animals through larval stages. Obtaining embryos for derivation requires approximately 1-2 h, with a 3- to 8-h incubation period before derivation. Derivation of GF animals takes 1-1.5 h, and daily maintenance requires 1-2 h.
