Passive exposure to cannabidiol oil does not cause microbiome dysbiosis in larval zebrafish

Abstract We show that 200 µg/L cannabidiol oil has a limited effect on in zebrafish larvae microbiome. Cannabidiol oil decreases the abundance of Methylobacterium–methylorubrum sp. Cannabidiol oil decreases the abundance of staphylococcus sp.,. Cannabidiol oil increased the abundance of chryseobacterium sp., a commensal bacterium. Our results suggest that cannabidiol oil is unlikely to have a major impact on local fauna. Authors: Maracela Talamantes, Stella Rose Schneeberg, Atahualpa Pinto, Gabriel G.
