Disappearance of Oxytetracycline Accumulation in the Cells of Multiple Drug-resistant Escherichia coli

Abstract

IN a previous communication1 we described the accumulation of a large amount of oxytetracycline related to the bactericidal action in the cells of E. coli. This accumulation seemed to be dependent on an energy-yielding system, since the presence of glucose was needed for the accumulation of oxytetracycline, and inhibitors such as 2,4-dmitrophenol and sodium azide inhibited the accumulation at low concentrations at which oxidation of glucose by the resting cells was not inhibited. However, recently, multiple drug-resistant bacteria have been found by many Japanese workers and many biochemical and genetic studies on these bacteria have been carried out2–6.
