| glutamate dehydrogenase from mycoplasma laidlawii. | mycoplasma laidlawii possesses a single glutamate dehydrogenase (gdh) with dual coenzyme specificity [specificity for nicotinamide adenine dinucleotide (h) and nicotinamide adenine dinucleotide phosphate (h)]. a purification procedure is reported which results in an enzyme preparation with a specific activity of 79.5 units/mg and which displays only one significant protein band after gel electrophoresis. this one band was determined, by activity staining, to have all of the gdh nucleotide specif ... | 1972 | 4112954 |

| detection of cholesterol in cell membranes by use of bacterial toxins. | a method is described for the detection of cholesterol in membranes from erythrocytes, mycoplasmas, and bacterial cells by a ferritin-labeling technique. membranes treated with cereolysin, a bacterial hemolysin which specifically binds to cholesterol, and then treated with ferritin-antitetanolysin, were specifically ferritin-labeled for cholesterol. a similar antigen-antibody system, streptolysin o-ferritin-antistreptolysin, was also used successfully with erythrocyte membranes. there was an une ... | 1972 | 4623312 |

| elimination of mycoplasma contaminants from virus stocks by treatment with nonionic detergents. | five nonionic detergents (tweens 20, 40, 60, and 80, and triton wr-1339) were tested for their ability to inactivate four mycoplasma species which are common contaminants of animal cell cultures. tween 20 was found to be the most effective, in that a concentration of 2.5 mg/ml completely inactivated cultures of m. hominis, m. hyorhinis, and acholeplasma laidlawii within 1 hr and a culture of m. orale within 3 hr. the other detergents exhibited various degree of activity against the different myc ... | 1972 | 4341521 |
| the structure of a glycerylphosphoryldiglucosyl diglyceride from the lipids of acholeplasma laidlawii strain b. | 1. the phosphatidylglucose structure proposed previously (smith & henrikson, 1965) for the glucose-containing phospholipid from acholeplasma laidlawii is incorrect. 2. the structure now proposed is 3-(sn-glycerol-3-phosphoryl-6'-[o-alpha-d-glucopyranosyl-(1-->2)-o-alpha-d-glucopyranosyl])- sn-1,2-diglyceride, a new type of bacterial lipid. 3. deacylation of the lipid gave a single water-soluble phosphate ester which could be distinguished on chromatography from synthetic samples of glucosylphosp ... | 1972 | 4345854 |

| thiopeptin, a new feed-additive antibiotic: biological studies and field trials. | thiopeptin is a new antibiotic, produced by streptomyces tateyamensis and developed solely for animal use as a feed additive. the antibiotic content in animal tissue and feed was assayed in terms of the antimicrobial activity against mycoplasma laidlawii a. this antibiotic was found to be relatively nontoxic in rats and mice. in chickens, this antibiotic is excreted into feces within 48 hr of administration and is not absorbed in tissue. it is well tolerated in both broilers and swine and is hig ... | 1972 | 4680812 |

| mycoplasma: growth precipitation as a serodiagnostic method. | a serological test is described which is designated the growth precipitation test and is based on the release of diffusible compounds from mycoplasma strains. during growth of mycoplasmas on solid substrates, precipitation lines are formed with antibodies from homologous antisera independent of heat-labile serum factors. the application of the test as a serodiagnostic tool was investigated by performing a complete serological cross-test with 10 mycoplasma strains. the test was compared with the ... | 1972 | 4623280 |

| transfection mediated by mycoplasmatales viral dna. | dna isolated from mycoplasmatales viruses mvl51 and mvgs51 was infectious when mixed with acholeplasma laidlawii bn1-na1(r) cells. infectivity was destroyed by deoxyribonuclease but not by ribonuclease, pronase, or specific antiserum to the virus. host mycoplasma cells were only competent for transfection during late-log growth phase. the rates of the establishment of dnase insensitivity of viral dna transfectants were similar to those of bacteriophage systems. the dose-response curve for transf ... | 1972 | 4508332 |

| osmolar concentration and fixation of mycoplasmas. | broth cultures of acholeplasma laidlawii were fixed with various concentrations of cacodylate-buffered glutaraldehyde. the shape and ultrastructure of the organisms varied with the osmolar concentration of the fixative. when the fixation mixture was hypertonic to the culture medium, ultrathin sections suggested that the cells had shrunk. phosphate buffer, sodium chloride, or sucrose at comparable osmolaities had the same effect as sodium cacodylate. glutaraldehyde itself also contributed to the ... | 1972 | 4555408 |

| acyl carrier protein in mycoplasmas. | acyl carrier protein (acp) activity was determined by the malonyl-coenzyme a-co(2) exchange reaction. it was highest in acholeplasma laidlawii, lower in a. granularum, and lowest in a. axanthum. the sterol-requiring mycoplasma species examined showed little or negligible acp activity. a. laidlawii was capable of utilizing pantetheine or coenzyme a but not beta-alanine as precursor for acp synthesis. its acp could thus be labeled by growing the organisms with radioactive coenzyme a. the acp of a. ... | 1973 | 4570599 |

| fusion of phospholipid vesicles with viable acholeplasma laidlawii. | when vesicles of dipalmitoyl phosphatidylcholine produced by sonication are mixed with acholeplasma laidlawii in neutral buffer, a phenomenon occurs that is most readily explained in terms of fusion of lipid vesicle membrane with the mycoplasma cytoplasmic membrane. the mycoplasma can readily accumulate large quantities of the foreign lipid without loss of viability. the added lipids do not remain in patches but diffuse laterally throughout the mycoplasma membrane. | 1973 | 4515622 |

| selective membrane toxicity of the polyene antibiotics: studies on natural membranes. | the effect of polyene antibiotics on candida albicans, human erythrocytes, and acholeplasma laidlawii was studied. the results sustain the observations made with lecithin-sterol liposomes. the distribution of double bonds in the membrane sterol nucleus appears to be of major importance in conferring polyene susceptibility; those sterols with the ergosterol nucleus are far more effective than those with a nucleus similar to cholesterol. different polyenes vary in their membrane selectivity. the c ... | 1973 | 4586145 |

| mycoplasma-associated induction of interferon in ovine leukocytes. | a mycoplasmal species, acholeplasma laidlawii, isolated as a contaminant from a fetal lamb kidney cell line, was shown to be associated with the induction of interferon in cultures of ovine peripheral blood leukocytes. broth cultures of the mycoplasma induced between 20 and 230 u of interferon per ml in leukocytes from two adult ewes. the amount of interferon produced correlated with the inoculum size of mycoplasma. interferon production was associated with replication of the mycoplasma in the l ... | 1973 | 4356073 |
| membrane lipids of mycoplasma hominis. | essentially all of the lipids of mycoplasma hominis (200 mug/mg of cell protein) were found to be located in the cell membrane. over one-half were neutral lipids incorporated from the growth medium and consisting of 43% free cholesterol, 19% esterified cholesterol, 23% triglycerides, 10% free fatty acids, and small amounts of di- and monoglycerides. the polar lipids accounting for about 40% of the total were synthesized by the organisms. phosphatidylglycerol was the predominant lipid of this fra ... | 1973 | 4347923 |
