KMO and Salmonella Infections: We have previously reported that administration of exogenous 3-HK promotes survival of zebrafish larvae to Salmonella Typhimurium infection by restricting bacterial expansion via a systemic mechanism that targets kainate sensitive glutamate receptor (KAR) ion channels and that the endogenous production of 3-HK by Kmo is required for defense against systemic Salmonella infection.
