α-Ketoglutarate downregulates thiosulphate metabolism to enhance antibiotic killing.

Potentiation of the effects of currently available antibiotics is urgently required to tackle the rising antibiotics resistance. The pyruvate (P) cycle has been shown to play a critical role in mediating aminoglycoside antibiotic killing, but the mechanism remains unexplored. In this study, we investigated the effects of intermediate metabolites of the P cycle regarding the potentiation of gentamicin.

Taurine promotes Oreochromis niloticus survival against Edwardsiella tarda infection.

Edwardsiella tarda represents one of the most important pathogens that infects a variety of hosts including aquatic animals and humans. The outbreak of E. tarda infection is frequently reported in aquaculture that causes huge economic loss.

Serine Metabolism Tunes Immune Responses To Promote Survival upon Infection.

Overactive immune response is a critical factor triggering host death upon bacterial infection. However, the mechanism behind the regulation of excessive immune responses is still largely unknown, and the corresponding control and preventive measures are still to be explored. In this study, we find that Nile tilapia, , that died from Edwardsiella tarda infection had higher levels of immune responses than those that survived.
