Abstract

SUMMARY: Mechanically disrupted cells of polymyxin E sensitive strains of and and a resistant strain of were studied in the electron microscope. The occurrence of a secondary layer or membrane was observed within the outer cell walls derived from and ; a similar structure was not observed in cell walls prepared from . Treatment of the disrupted cells of and with polymyxin E resulted in marked morphological changes, whilst similar exposure of cell walls to the antibiotic produced no significant changes in their morphology.
