outgrowth of bacillus cereus spores harboring bacteriophage cp-51 dna. i. initiation of bacteriophage development.time of initiation of bacteriophage cp-51 rna synthesis, inhibition of host dna synthesis, initiation of cp-51 dna synthesis, and release of phage was determined in infected bacillus cereus cells and outgrowing spores harboring phage dna. the development of phage in outgrowing spores is initiated 45 min after induction of spore germination and then proceeds at a rate similar to that observed in infected cells. although spore rna synthesis is inhibited by the presence of chloramphenicol or puromy ...19734196633

the relative susceptibility of four cephalosporins to a beta-lactamase from bacillus cereus.the effects of purified beta-lactamase from bacillus cereus on the activity of four cephalosporins are described. drug inactivation was measured spectrophotometrically and confirmed by microbiological assay and by microbiological techniques involving determinations of minimum inhibitory concentrations and growth curves of staphylococcus aureus nctc 6571 (oxford) in broth containing drug +/- enzyme. cephaloridine was the most sensitive of the four cephalosporins, followed by cephalothin and the s ...19734206088

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

chemical composition and ultrastructure of native and reaggregated membranes from protoplasts of bacillus cereus.conditions were defined for producing protoplasts with lysozyme and isolating the protoplast membranes from cells of bacillus cereus t harvested late in the exponential growth phase just before sporogenesis. the membranes contained approximately 60% protein, 30% lipid, 6% carbohydrate, and 1% ribonucleic acid. seventeen proteins were distinguished by molecular size in the membrane solubilized with sodium dodecyl sulfate, and 12 in that with phenol and acetic acid. the lipid fraction consisted of ...19744205199

use of ultraviolet radiation to locate dipicolinic acid in bacillus cereus spores.a novel method is described that allows a direct determination of the location of a portion of the dipicolinic acid (dpa) in spores. ultraviolet (uv) irradiation is shown to cause cross-linkage of dpa to spore proteins which have the characteristics of membrane proteins. we suggest that dpa resides in the inner forespore membrane (ifsm) and spore cytoplasm (i.e., the spore protoplast). only that portion of the dpa in the vicinity of the ifsm appeared to form uv-induced dpa-protein adducts.19744206870
phospholipid metabolism and membrane synthesis during sporulation in bacillus megaterium.in view of previously published reports of localized membrane growth in exponentially growing bacillus megaterium and in sporulating bacillus cereus, an attempt was made to describe phospholipid metabolism and the topology of membrane synthesis during sporulation in b. megaterium. the cells were pulsed with radioactive glycerol or acetate at the time of septum formation, and the specific activity of the lipid fraction was measured at various times through the free spore stage. the bulk of the ma ...19744206872
early biochemical events occurring after infection of bacillus cereus 569-sp1 with bacteriophage gsw.after infection of bacillus cereus 569-sp1 with the 5-hydroxymethyluracil-containing phage gsw, new dttpase, dutpase, and dump-hydroxymethylase activities appear. no significant changes in activities of other pyrimidine ribonucleoside or 2'-deoxyribonucleoside triphosphate nucleotidohydrolases were detected. dutp and dump inhibit the dttpase activity, whereas dttp failed to inhibit dutpase activity. the k(m) value for the substrate dutp is 10(-4) m and for dttp is 4.85 x 10(-4) m. thymidylate sy ...19744206941

alteration of vascular permeability in rabbits by culture filtrates of bacillus cereus and related species.crude culture filtrates of strains of bacillus cereus, b. thuringiensis, and b. mycoides caused an increase in vascular permeability when injected intradermally into rabbits. the time course of the change in permeability was determined, and could easily be distinguished from a more transient effect induced by purified (from b. cereus) phospholipase c. the properties of the responsible factor were found to be similar to those reported for the guinea pig dermal factor and the ileal loop fluid indu ...19744211786

specimen holder to critical-point dry microorganisms for scanning electron microscopy.critical-point drying of microorganisms for scanning electron microscopy can be rapidly and effectively accomplished by use of a newly described specimen holder. up to eight different samples of spores or vegetative cells are placed between polycarbonate membrane filters in the holder and processed through solvent dehydration and critical-point drying using carbon dioxide without loss or cross contamination of microorganisms. yeasts, molds, bacteria, and actinomycetes have been successfully proc ...19744213985
photoreactivation, photoproduct formation, and deoxyribonucleic acid state in ultraviolet-irradiated sporulating cultures of bacillus cereus.photoreactivation of ultraviolet-irradiated bacillus cereus t declined markedly during the development of stage iv forespores. during ultraviolet irradiation of a culture containing early and late stage iv forespores, both vegetative- and spore-type photoproducts were formed. the formation of vegetative-type photoproducts (mainly thymine dimers) decreased to nearly half during late stage iv, remaining constant until lysis of the mother cells began, when it fell to zero. spore-type photoproducts ...19744214215

polysaccharide that may serve as a carbon and energy storage compound for sporulation in bacillus cereus.an intracellular, glucose-containing polysaccharide accumulates in bacillus cereus early in sporulation and is degraded at the time of spore maturation. this pattern of accumulation and degradation occurred when growth was limited by glucose or a component of yeast extract. these data suggest that the polysaccharide may be serving as a carbon and energy storage compound for sporulation. a somewhat similar pattern of accumulation and degradation of poly-beta-hydroxybutyric acid (phb) was shown ea ...19744214355
