the ultrastructural analysis of a stable spheroplast type l-form of proteus mirabilis d 52 revealed characteristic alterations in the organization of the cell envelope including defective changes in the cell envelope structure as for instance the loss of a coherent murein layer , the loss of some components in the outer cell wall layer , the formation of small membraneous vesicles at the tips of loose extensions of the cell wall , a decrease in associations and bindings between wall and membrane , an extension of the periplasmic space , an increase in membrane defects , as well as a disturbed cell division causing unusual modes of multiplication and the formation of various intracellular structures like membrane complexes , characteristic sheet-like membraneous bodies , typical inclusion bodies , and defective phage structures , which all could not be observed in normal rod-shaped cells .
