variation of type-b dna x-ray fiber diagrams with base composition.eight natural dnas of widely differing base composition have been studied by x-ray diffraction in fibers at high relative humidity. the resulting type b diffraction diagrams showed that all of the dnas had a 34-a pitch and 3.4-a interbase pair separation. however, the intensity distribution on the inner three layer lines was a strong function of the base content. in diffraction diagrams of very at-rich dna, the intensity of the first and third layer line was 2- or 3-times stronger than in the pa ...19734352977

collagenolytic activity of dental plaque associated with periodontal pathology.certain dental plaques, removed from sites of gingival and periodontal pathology in mentally retarded, institutionalized individuals, when incubated in phosphate buffer with achilles tendon collagen, gave rise to an increase in ninhydrin-positive material. these plaques, while showing great variability, released significantly more ninhydrin-positive material per milligram of plaque (wet weight) than did either the endogenous or heat-treated controls. certain plaques could also break down soluble ...19744361294

d-amino acid oxidase induction in the kidneys of germ-free mice.high levels of d-amino acid oxidase activity were found in the kidneys of conventionally reared mice, whereas the enzyme was absent from the kidneys of most germ-free mice. injection of d-alanine or monocontamination with bacillus cereus stimulated d-amino acid oxidase activity in the kidneys of germ-free mice.19684389707

characteristics of a bacteriocin derived from streptococcus faecalis var. zymogenes antagonistic to diplococcus peumoniae.a bacteriocin-producing strain of streptococcus faecalis var. zymogenes (e-1) was isolated from clinical material (conjunctiva). the active substance differed from bacteriocins described by other investigators primarily in its spectrum of antibacterial activity, especially by its marked inhibition of diplococcus pneumoniae. the e-1 bacteriocin also inhibited nonhemolytic strains of enterococci as well as one-third of the viridans group of streptococcal strains investigated. the degree of inhibit ...19714398532

conformational changes in the extracellular beta-lactamase i from bacillus cereus 569/h/9.1. the thermal denaturation and precipitation of beta-lactamase i from bacillus cereus 569/h/9 at 60 degrees c are reversible, a soluble and almost fully active enzyme being obtained after solution of the precipitate in 5m-guanidinium chloride or 8m-urea and subsequent removal of the denaturing agent. 2. inactivation of beta-lactamase i occurs rapidly between 50 degrees and 55 degrees c and is shown by circular-dichroism spectra to be accompanied by an extensive conformational change. 3. a chang ...19744464849
method for restricting incorporation of radioactivity from 3 h-thymidine into deoxyribonucleic acid only during outgrowth of spores of bacillus cereus t.when heat-activated spores of bacillus cereus t (thy(-)) were germinated and grown in medium containing (3)h-thymidine, a significant amount of radioactivity was incorporated into ribonucleic acid and deoxyribonucleic acid (dna). a method was developed to restrict the incorporation of radioactivity from (3)h-thymidine into dna only. this was accomplished by labeling the cells with (3)h-thymidine in the presence of 2 mg of 2-deoxyadenosine per ml, 250 mug each of uracil, cytosine, and guanosine p ...19724621680
nature of deoxyribonucleic acid synthesis and its relationship to protein synthesis during outgrowth of bacillus cereus t.deoxyribonucleic acid (dna) synthesis during early outgrowth of spores of bacillus cereus t (thy(-)) has been examined. (14)c-thymidine incorporated begins 2 to 5 min after germination and continues at a slow rate up to 30 min, after which the rate of (14)c-thymidine incorporation increases considerably. early dna synthesis up to 30 min after germination is dependent upon simultaneous protein synthesis. the examination of the stability of proteins synthesized soon after germination shows that th ...19724621681

antimicrobial properties of natural phenols and related compounds: obtusastyrene and dihydro-obtusastyrene.factors influencing the antimicrobial properties of obtusastyrene and dihydro-obtusastyrene were studied. both of these compounds were soluble in acetone, alcohol, and olive oil. in water, they were soluble at concentrations of 34 and 53 mug/ml, respectively. the minimal inhibitory concentrations against gram-positive bacteria and yeast were below 100 mug/ml. the compounds were not effective against gram-negative bacteria at 200 mug/ml or lower concentrations. with initial populations of cells g ...19724625626

regulation of dipicolinic acid biosynthesis in sporulating bacillus cereus. characterization of enzymic changes and analysis of mutants.some of the early enzymes in the lysine-biosynthetic pathway also function for dipicolinic acid synthesis in sporulating bacillus cereus t. 1. the first enzyme, aspartokinase, loses its sensitivity to feedback inhibition by lysing. this change occurs before the time of dipicolinic acid synthesis but at a time when diaminopimelic acid is required for spore cortex formation. 2. a possible regulatory change at a branch point in the pathway was studied by examining the properties of a key enzyme, di ...19724627586

location of calcium within bacillus spores by electron probe x-ray microanalysis.spectroscopic microanalysis of the element-characteristic x rays produced by a scanning electron microprobe was employed to detect calcium and carbon in both intact and thin-sectioned spores of bacillus cereus t and b. megaterium qm b1551. linear scan profiles and multilinear scan images of the x-ray emissions for calcium (ca(kalpha)) were compared with those for carbon (c(kalpha)) as an index of mass. location was accomplished by stereological comparisons with secondary electron images and conv ...19724627927
bacillus cereus-induced fluid accumulation in rabbit ileal loops.the usefulness of the ligated rabbit ileal loop as an experimental model of bacillus cereus food poisoning was investigated. positive responses, as measured by fluid accumulation in the loop, were obtained from 19 of 22 strains of b. cereus. four of six strains of b. thuringiensis also elicited fluid accumulation, but eight strains of other bacillus spp. failed to evoke a response. the growth medium employed markedly affected the ability of a given strain of b. cereus to provoke a response. brai ...19724627964
effect of ultrasonic waves on the heat resistance of bacillus cereus and bacillus licheniformis spores.heat resistance of bacillus cereus and bacillus licheniformis spores in quarter-strength ringer solution decreases markedly after ultrasonic treatments which are unable to kill a significant proportion of the spore population. this effect does not seem to be caused by a loss of ca(2+) or dipicolinic acid. the use of ultrasonics to eliminate vegetative cells or to break aggregates in bacillus spore suspensions to be used subsequently in heat resistance experiments appears to be unadvisable.19724627969
