AbstractVibrio cholerae, the etiological agent of cholera, employs quorum sensing (QS) pathways to control the expression of virulence factors, including the production of cholera toxin and biofilm formation. Acquired antibiotic resistance inV. choleraedraws attention to the development of novel therapeutics that counteract virulence, rather than the viability of the pathogen. In this context, we explored the anti-infective potential of rare marine Actinobacteria (RMA) from a mangrove ecosystem. Here, we report the effects ofMicromonosporasp. RMA46 againstV. cholerae in vitro. The RMA46 organic extract was non-bactericidal toV. choleraecells and non-cytotoxic to macrophage RAW264.7 cell lines. RMA46 inhibited the formation ofV. choleraebiofilms and downregulated the QS global switches LuxO and HapR, as well as other virulence genes includingct,tcp, andhapA.In silicomolecular docking simulation of RMA46 ethyl acetate extract with LuxO and HapR revealed that 2-methoxy-4-vinylphenol and hexahydro-3-(phenylmethyl)-pyrrolo[1,2-a]pyrazine-1,4-dione could interact with the active sites of LuxO and HapR and potentially inhibit them. This study highlightsMicromonosporasp. RMA46 as a potential source of anti-infectives againstV. cholerae.
