Infection of Acholeplasma laidlawii by MVL51 virus

Virology, 1973
The infection of Acholeplasma laidlawii cells by MVL51 virus has been studied, MVL51 is a bullet-shaped virus, about 14 nm wide and 71 nm long. At multiplicities of infection less than 10, virus infected cells continue to grow during virus production, but the cell doubling time is 160 min, rather than the normal 110 min.

Evidence for the bacterial origin of Acholeplasma laidlawii A

Diagnostic Microbiology and Infectious Disease, 1985
L-forms from a Corynebacterium were induced in hyperosmolar media and gradually adapted to normal osmolarity over a period of two years. During this adaptation several morphologic L-form variants derived from the L-form cultures and were serologically identified as Acholeplasma laidlawii A.

Adaptation of Mycoplasmas to Antimicrobial Peptides: Development of Melittin Resistance in Acholeplasma laidlawii Is Associated With Changes in Genomic and Proteomic Profiles and in Virulence

Doklady Biochemistry and Biophysics, 2020
© 2020, Pleiades Publishing, Ltd. Abstract: For the first time it is shown that the development of resistance to melittin in Acholeplasma laidlawii, a mycoplasma that is widely spread in nature and that is the main contaminant of cell cultures and ...

The molecular structure of the membrane of Acholeplasma laidlawii

Chemistry and Physics of Lipids, 1972
Abstract The following discussion is a survey of experiments with the membrane of Acholeplasma laidlawii (formerly Mycoplasma laidlawii)3–5). This organism is particularly suitable for membrane structural studies, since it has only a single membrane which is easily isolated by osmotic lysis and since it lacks the specialized wall structures of the ...

The enzymatic synthesis of membrane glucolipids in Acholeplasma laidlawii

Biochimica et Biophysica Acta (BBA) - Biomembranes, 1992
In membranes of the prokaryote Acholeplasma laidlawii, the physiological regulation of the two major membrane lipids, monoglucosyldiacylglycerol (MGlcDAG) and diglucosyldiacylglycerol (DGlcDAG), is governed by factors affecting the equilibria between lamellar and non-lamellar phases of the membrane lipids. The synthesis of the glucolipids is considered

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.
