nucleic acid synthesis in bacillus subtilis infected with bacteriophage beta-22.changes in the synthesis of host and phage nucleic acid after infection of bacillus subtilis with virulent bacteriophage beta22 were analyzed by deoxyribonucleic acid (dna)-dna and ribonucleic acid (rna)-dna hybridization. host dna replication continued during the first third of the 55-min latent period and then ceased at approximately the time replication of the phage genome was initiated. host-specific rna was synthesized concurrently with phage rna during the first half of the latent period b ...19704993332

effect of relative humidity on the penetrability and sporicidal activity of formaldehyde.the effect of relative humidity (rh) on formaldehyde penetration of paper, glassine, and cotton was determined by the death rate of bacterial spores in glass tubes covered with these materials. the data show that paper is readily penetrated regardless of rh, but the rh greatly affects the penetration rate of glassine and cotton. a comparison was also made of the effect of rh on the penetrability of formaldehyde generated from formalin and paraformaldehyde. at low rh, all three closures were pene ...19704993359
reversible inhibition of spore germination by alcohols.low levels of alcohols have been found to inhibit the process of spore germination. the extent of germination is dependent upon the concentration of alcohol present in the germinating medium. this inhibition is reversible since removal of the alcohol from the spore environment allows germination to proceed.19704993360

symmetric replication of the bacillus subtilis chromosome.synchronously replicating chromosomes in germinating spores of bacillus subtilis were labeled near the origin with [(3)h]bromouracil. the label appeared in heavy-light dna. when cell growth and chromosome replication were continued in unlabeled bromouracil, nearly all the tritium label was transferred to heavy-heavy dna while the terminus remained unreplicated. this implies that both origins of the replicating chromosome can undergo reinitiation. therefore, during multifork replication the chrom ...19705002094

paper chromatographic techniques for the determination of cephalothin and desacetylcephalothin in body fluids.paper chromatographic procedures may be used to detect cephalothin and its metabolite desacetylcephalothin in urine, plasma, synovial fluid, and cerebrospinal fluid. protein-bound antibiotics are released from plasma, cerebrospinal fluid, and synovial fluid by dilution with an equal volume of dimethylformamide. data are presented on the sample preparation, paper chromatographic system, and other specific techniques.19704991918
adsorption of formaldehyde by various surfaces during gaseous decontamination.study of the effect of atmospheric relative humity (rh) on the adsorption of paraformaldehyde-generated formaldehyde gas on various surfaces and the effect of the adsorbed formaldehyde on the death rate of bacterial spores showed that increasing the rh caused a corresponding increase of formaldehyde levels on all surfaces. the amount peaked at 83% rh. the levels obtained at 100% rh were slightly below those at 83% rh. cotton cloth had a much greater affinity for the gas at all rh than either gla ...19704991921
ethylene oxide resistance of nondesiccated and desiccated spores of bacillus subtilis var. niger hermetically sealed in various polymeric films.the resistance to destruction of spores of bacillus subtilis var. niger hermetically sealed in various polymeric films and exposed to ethylene oxide with and without relative humidity was determined. the effect of desiccation was also determined. the order of increased resistance to sterilization with regard to type of polymeric film was found to be: polyethylene equal to polyvinyl chloride, less than nylon, less than cellophane/polyethylene laminate, less than phenoxy, less than mylar/polyethyl ...19704991923
sterility test method for petrolatum-based ophthalmic ointments.a sensitive sterility testing procedure for the detection of microbial contamination in petrolatum-based ointments is described. the method involves dissolving the ointment in filter-sterilized isopropyl myristate and filtering through a membrane filter. improved sensitivity is obtained by blending the membrane in trypticase soy broth before incubation. filter-sterilized isopropyl myristate is shown to be less toxic to microorganisms than heat-sterilized isopropyl myristate. the isopropyl myrist ...19704991924
microcount method for petrolatum-based topical ointments containing waxes.a practical solvent system for the detection of microorganisms in topical ointments has been developed. the method involves dissolving 0.5 g of topical ointment in 50 ml of a solvent mixture (92 parts isopropyl myristate, 6 parts carbon disulfide, and 2 parts xylene) and filtering it through a 0.45-mum membrane filter. residual solvent is then washed from the filter pad with 200 ml of sterile 0.5% brain heart infusion broth containing 0.1% tween 80. the filter pad is then removed and placed on a ...19704991925
dry-heat destruction of bacillus subtilis spores on surfaces: effect of humidity in an open system.bacillus subtilis var. niger spores were tested for dry-heat resistance on stainless-steel strips hung in an oven. heat resistance was dependent on the relative humidity before and during treatment, which in turn affected the water content of the spores. higher humidities increased the heat resistance of the spores. d-values ranged from 16.1 min for spores conditioned at <2% relative humidity (rh) and treated at 0.34% rh to 37.6 min for spores conditioned at 89% rh and treated at 1.1% rh. the y- ...19704991926
resistance of bacillus subtilis spores to inactivation by gamma irradiation and heating in the presence of a bactericide. i. suitability of viable count procedures.a statistical evaluation of viable count procedures utilized for obtaining treatment survival curve data for bacillus subtilis nctc 8236 spores is described. within the various recovery conditions tested, incubation on nutrient agar containing 1% dextrose for 48 hr at 37 c was found to promote the highest count of viable spores surviving a variety of bactericidal treatments involving gamma irradiation, heat, and chlorocresol. the count of viable spores on the medium was not significantly altered ...19704991959
resistance of bacillus subtilis spores to inactivation by gamma irradiation and heating in the presence of a bactericide. ii. factors affecting rates of inactivation by phenolic bactericides.aqueous suspensions of bacillus subtilis nctc 8236 spores, surviving 150,000 or 300,000 rad of gamma irradiation under air from a cesium-137 source, exhibited an enhanced rate of inactivation, compared to nonirradiated spores, when heated with different phenolic bactericides. the apparent magnitude of the enhanced inactivation rate, observed from survival curves, increased progressively with the irradiation dose applied and diminished progressively as the severity of heat treatment with 0.2% chl ...19704991960

investigation of the penicillinase activity in l colonies of staphylococcus aureus.penicillinase-producing strains of staphylococcus aureus are transformed into stable l colonies by 70 to 100 subcultures on methicillin-containing medium with a suitable high osmolarity. during transformation, the penicillinase activity is lost. this loss in activity is not the result of only the penicillinase-negative mutants transforming to l colonies. if unstable l colonies are filtered through 0.45-mum membrane filters immediately after transformation, still no penicillinase activity is seen ...19704992652
effects of atmospheric humidity and temperature on the survival of airborne flavobacterium.the survival of airborne flavobacterium sp. in particle sizes ranging from 1 to 5 mum was significantly influenced by atmospheric temperature. a progressive increase in temperature from -18 to 49 c resulted in increases in death rates of the airborne organism. the lowest death rates were observed in the temperature range of -40 to -18 c, and the highest death rates were observed in the 29 to 49 c range. at 24 c, the survival of airborne flavobacterium did not appear to be significantly affected ...19704992653

6-(p-hydroxyphenylazo)-uracil: a selective inhibitor of host dna replication in phage-infected bacillus subtilis.the azopyrimidine, 6-(p-hydroxyphenylazo)-uracil, inhibits the replication of bacterial dna selectively, completely, and reversibly, and has no apparent effects on the metabolism of other cellular macromolecules thus far examined. the mechanism of its action has been investigated in uninfected and phage-infected bacillus subtilis, and the compound appears to be specific for a host function. in cells infected with virulent phage the synthesis of phage dna proceeds normally, while residual host dn ...19704992015
