Effect of acriflavine on ultraviolet inactivation of Acholeplasma laidlawii

Biochimica et Biophysica Acta (BBA) - General Subjects, 1978
An increased sensitivity to inactivation was observed when ultraviolet light-irradiated Acholeplasma laidlawii cells were plated on medium containing either acriflavine or chloramphenicol. Chloramphenicol reduced liquid holding recovery (dark repair) to about 10% of that in untreated irradiated cells.

Electron microscope observations on Acholeplasma laidlawii viruses

Archiv f�r die gesamte Virusforschung, 1972
Cultures ofAcholeplasma laidlawii were inoculated with Mycoplasmatales virus-laidlawii 1 (MV-L 1) and examined by light and electron microscopy.A. laidlawii colonies that appeared collapsed or “cratered” were seen by electron microscopy to contain numerous rod-shaped virus particles, about 86 nm long and 13 nm wide, whereas these were not seen in ...

Radioprotection of Acholeplasma Laidlawii B by Cysteine

International Journal of Radiation Biology and Related Studies in Physics, Chemistry and Medicine, 1974
SummaryThe radioprotective activity of cysteine is progressively destroyed by ionizing radiation greater than 28·8 krads. Acholeplasma laidlawii B cells are protected after brief pre-irradiation exposure to cysteine, and this response may be membrane-mediated.

Receptor Sites for Mycoplasmal Viruses on Acholeplasma laidlawii

Clinical Infectious Diseases, 1982
All three groups of mycoplasmal viruses tested, MVL1, MVL2, and MVL3, were inactivated by both membranes and lipoglycan from Acholeplasma laidlawii strain JA1. The interaction was specific for components of A. laidlawii since no inactivation occurred with either membrane or lipoglycan from Acholeplasma oculi.

The distribution of molecular classes of phosphatidylglycerol in the membrane of Acholeplasma laidlawii

Biochimica et Biophysica Acta (BBA) - Biomembranes, 1978
A double-label technique has been applied to study the distribution of different molecular classes of phosphatidylglycerol in the membrane of Acholeplasma laidlawii. After growth on oleic acid, 16% of the total phosphatidylglycerol contains two oleic acid residues and 84% contains one oleic acid and one saturated fatty acid.

Control of fatty acid composition of Acholeplasma laidlawii membranes

Biochimica et Biophysica Acta (BBA) - Biomembranes, 1977
The temperature-dependent pattern of incorporation of palmitate and oleate from the growth medium into Acholeplasma laidlawii membrane lipids correlates with the physical state of the membrane defined by calorimetry. Both the pattern and the state can be changed at will by changing the fatty acid composition of the membrane lipids.

Thermal-Turbidimetric studies of membranes from Acholeplasma laidlawii

Biochimica et Biophysica Acta (BBA) - Biomembranes, 1972
Light scattering measurements were made of aqueous dispersions of Acholeplasma laidlawii membranes as well as lipids extracted from these membranes. As the temperature was increased the turbidity values changed over a temperature range that was dependent upon the fatty acid residues present in the membrane lipids.

[Acholeplasma laidlawii--a pathogenic or apathogenic species?].

Archiv fur experimentelle Veterinarmedizin, 1980
The question is discussed, whether Acholeplasma laidlawii is a pathogenic or apathogenic species. Studies have shown that it is a species of potential pathogenicity, however, with virulence properties differing greatly by strains. Nothing so far has become known of contributive factors which might be needed for an infectious disease to develop.

Silicotungstate negative staining of Acholeplasma laidlawii membranes and lipids

Journal of Ultrastructure Research, 1972
Acholeplasma membranes rich in oleic or crucic acids display extensive irregularly shaped filamentous structures 100–400 A in diameter after negative staining with silicotungstate (STA). The same membranes appear vesicular when examined by other negative stains and other preparative techniques.

Localization of Phosphatidylglycerol in the Membrane of Acholeplasma laidlawii

1984
The two layers of a biological membrane can have different phospholipid compositions. A good example of this is the erythrocyte membrane, where the outer layer consists mainly of choline-containing phospholipids, whereas the aminophospholipids are found preferentially in the inner layer.
