چکیده

An Acholeplasma laidlawii variant has been isolated that has a REP- phenotype. The properties of this variant, relative to parental cells, are: (i) it exhibits no change in cell growth kinetics; (ii) it does not propagate single-stranded deoxyribonucleic acid (DNA) mycoplasmaviruses but does propagate double-stranded DNA mycoplasmaviruses; (iii) it converts parental circular single-stranded mycoplasmavirus DNA to double-stranded replicative forms that are not replicated further; (iv) it exhibits no change in host modification and restriction; and (v) it has an increased ultraviolet light sensitivity. The REP- isolate is the first stable mycoplasma variant to which a physiological defect has been attributed.

Interaction of mycoplasma virus type 2 with cellular components of Acholeplasma laidlawii strain JA1.

Mycoplasma virus type 2 was shown to adsorb specifically to intact cells, membranes, and lipoglycan of Acholeplasma laidlawii strain JA1 but not to these components of Acholeplasma oculi. The oligosaccharide chain of the lipoglycan defined the specificity of the receptor site since deacylation not only did not reduce adsorption but increased it threefold. Actual adsorption of virus to lipoglyca...
