LIGHT AND ELECTRON MICROSCOPIC STUDIES OF ESCHERICHIA COLI-COLIPHAGE INTERACTIONS III

Abstract
2,3,5-Triphenyltetra-zolium reductase activity was found to remain at a constant level during the latent period of T2r infection of Escherichia coli, strain B, growing in unaerated complex medium. Microscopic examination revealed that, while the nuclei were disrupted early in the latent period, the tetrazolium reductase activity of the mitochondria persisted in these discrete loci until lysis of the cells.
