Induction of C4-dicarboxylate transport genes by external stimuli in Rhizobium meliloti.

abstract：:The mouse model of intraperitoneal sepsis with Proteus rettgeri was used to evaluate the anti-endotoxic effect of polymyxin B sulfate. An unexpected reversal of the usual protective effect of polymyxin in experimental enterobacterial sepsis was observed in which the lethality of the infection was enhanced. ...
