cores, microbial organelles possibly specific to group d streptococci.a long, thin, approximately cylindrical core spans the interior of cells of 24-hr cultures of all group d streptococci that were examined, five strains of streptococcus faecalis, single strains of s. faecalis subsp. zymogenes and s. durans, and three strains of streptococcus spp. in one strain of s. faecalis, serial section electron microscopy showed that most cells possess a core. the core is 0.10 to 0.16 mum thick and consists of a matrix and an axial array of ribosomelike particles. it resemb ...19684971888
transport of aminophosphonic acids in lactobacillus plantarum and streptococcus faecalis.aminophosphonic acids analogous to glutamic acid, aspartic acid, alanine, and valine were actively accumulated by lactobacillus plantarum. uptake was dependent on the availability of glucose and, in all cases, the estimated intracellular concentrations substantially exceeded extracellular levels. during uptake, there was little metabolism of tritiated 2-amino-3-phosphonopropionic acid (app), the aspartic acid analogue, and a negligible incorporation of isotope from this substance into the nuclei ...19684971894

bacteriocin (hemolysin) of streptococcus zymogenes.the sensitivity of streptococcus faecalis (attc 8043) to s. zymogenes x-14 bacteriocin depends greatly on its physiological age. sensitivity decreases from the mid-log phase on and is completely lost in the stationary phase. the sensitivity of erythrocytes to the hemolytic capacity of the bacteriocin showed considerable species variation. the order of increasing sensitivity was goose < sheep < dog < horse < human < rabbit. however, when red cell stromata were used as inhibitors of hemolysis in a ...19684972910
differentiation of streptococcus faecalis andrewes and horder and streptococcus faecium orla-jensen based on the amino acid composition of their murein.the amino acid composition of the murein (peptidoglycan) of 75 strains of enterococci was investigated. all strains designated streptococcus faecalis according to their physiological properties contained the lysine-alanine type of murein; all strains classified as s. faecium contained the lysine-aspartic acid type of murein.19684972913

thermal injury and recovery of streptococcus faecalis.exposure of streptococcus faecalis r57 to sublethal heating produced a temporary change in the salt tolerance and growth of the organism. after sublethal heat treatment at 60 c for 15 min, greater than 99.0% of the viable population was unable to reproduce on media containing 6% nacl. in addition, the heated cells displayed a sensitivity to incubation temperature, ph, and 0.01% methylene blue. when the injured cells were placed in a synthetic medium, recovery occurred at a much slower rate than ...19684973066
autolytic enzyme system of streptococcus faecalis. iv. electron microscopic observations of autolysin and lysozyme action.cell walls (log walls) were isolated from cultures of streptococcus faecalis atcc 9790 in the exponential phase of growth. these walls were either allowed to undergo autolytic dissolution (in the presence or absence of trypsin) or wall autolysis was inactivated with sodium dodecylsulfate (sds walls). inactivated walls were treated either with lysozyme or with isolated, partially purified s. faecalis autolysin. during wall lysis, samples were removed, negatively stained with phosphotungstate, and ...19684973130

molar growth yields of certain lactic acid bacteria as influenced by autolysis.molar growth yields determined from batch cultures of streptococcus diacetilactis and s. faecalis were appreciably greater at the peaks of maximal growth than after continued incubation and considerable autolysis. the higher molar growth yields were about equal to those determined in a continuous culture. autolysis during logarithmic growth was minimal. the average y value for adenosine triphosphate (atp), determined by using limiting concentrations of glucose, galactose, lactose, and maltose fo ...19684969603
effect of different media on in vitro studies of antibiotic combinations.in an effort to determine the adequacy of a standard broth medium in the evaluation of antibiotic combinations, 20 strains of various bacterial species were studied simultaneously in mueller-hinton broth and in freshly drawn human serum from apparently healthy volunteers. studies of growth dynamics by use of the usual plate dilution technique for quantitating colony-forming units were performed with strains of staphylococcus aureus (methicillin-resistant and methicillin-susceptible), streptococc ...19684969662

effects of nigericin and monactin on cation permeability of streptococcus faecalis and metabolic capacities of potassium-depleted cells.at a concentration of 10(-6)m, nigericin and monactin inhibited growth of streptococcus faecalis, and the inhibition was reversed by addition of excess k(+). in the presence of certain antibiotics, the cells exhibited increased permeability to certain cations; internal rb(+) was rapidly lost by exchange with external h(+), k(+) rb(+), and, more slowly, with na(+) and li(+). no effect was observed on the penetration of other small molecules. cation exchanges induced by nigericin and monactin were ...19684966827
effect of hydroxylysine on the biosynthesis of lysine in streptococcus faecalis.we were able to show that two lysine-independent mutants of streptococcus faecalis atcc 8043 contained the enzymes for the usual bacterial pathway for lysine biosynthesis. because of this synthetic capacity, one mutant, the lys(+)ohlys(s) strain, could not grow in the presence of hydroxylysine without a lysine supplement. both lysine and hydroxylysine inhibited the first enzyme of the pathway, aspartokinase. unlike the escherichia coli enzyme, s. faecalis dihydrodipicolinic acid synthetase was n ...19684966828

in vivo and in vitro action of norethindrone on staphylococci.norethindrone has been examined in vitro for antibacterial activity against 10 microorganisms. turbidimetric techniques were used to assay the antibacterial activity of norethindrone. the organisms tested included staphylococcus aureus, s. epidermidis, micrococcus conglomeratus, listeria monocytogenes, streptococcus faecalis, salmonella typhosa, shigella flexnerii, klebsiella pneumoniae, escherichia coli, and proteus vulgaris. bacteriostatic action was shown only against the gram-positive microo ...19674964476
role of the phagocyte in host-parasite interactions. xii. hydrogen peroxide-myeloperoxidase bactericidal system in the phagocyte.an antimicrobial system in polymorphonuclear neutrophils (pmn) consisting of myeloperoxidase and hydrogen peroxide has been proposed. this system appears to be activated during phagocytosis as a result of the stimulated metabolic activities. a lysed-granules (lg) fraction was prepared from guinea pig exudative pmn. lg alone possessed bactericidal activity which was related to the ph of the reaction; the lower the ph, the more marked the activity. when low concentrations of both h(2)o(2) and lg w ...19674964478
energies of activation and uncoupled growth in streptococcus faecalis and zymomonas mobilis.growing cultures of streptococcus faecalis at temperatures above 30 c have activation energies for both rates of growth and glycolysis of 10.3 kcal mole(-1), and a constant growth yield; when growth takes place below this temperature, the growth yield decreases and the activation energy for growth increases to 21.1 kcal mole(-1), but the activation energy for glycolysis is unchanged. the adenosine triphosphate pool in the organisms behaves differently above and below 30 c, suggesting that the en ...19674964479
autolytic enzyme system of streptococcus faecalis. 3. localization of the autolysin at the sites of cell wall synthesis.cell walls from exponential-phase cultures of streptococcus faecalis atcc 9790 autolyzed in dilute buffers. walls were isolated from cultures grown in the presence of (14)c-lysine for about 10 generations and then on (12)c-lysine for 0.1 to 0.8 of a generation (prelabeled). these walls released (14)c to the soluble fraction more slowly than they lost turbidity during the initial stages of autolysis. walls isolated from cultures grown in the presence of (14)c-lysine for only the last 0.1 to 0.4 o ...19674964481
group q streptococci. i. ecology, serology, physiology, and relationship to established enterococci.the group q streptococci possess unique serological and physiological characteristics which differentiate them from established enterococci. the group q antigen was not demonstrable in all strains; however, all possessed the group d antigen. all group q strains were physiologically similar regardless of whether or not they possessed the group q antigen. these strains differed from the established enterococcal species, as they neither hydrolyzed arginine nor initiated growth in 1.0% methylene blu ...19674962699
group q streptococci. ii. nutritional characteristics and growth relationship to thymine, folate, and folinate.the vitamin requirements of the group q streptococci (streptococcus avium) and the established enterococcal species (s. faecalis and s. faecium) paralleled one another, although s. avium did not characteristically require riboflavine or pyridoxal. s. avium was further differentiated in that it required thymine for growth initiation whether or not folate was present. folate was stimulatory in the presence of sub-optimal concentrations of thymine, as well as during the early growth period with opt ...19674962700
effect of algicidal quaternaries on the germicidal activity of chlorine on swimming pool water.the swimming pool water disinfectant test method of the association of official analytical chemists was used to determine the effect of the accepted level of 2 ppm of some commercial quaternary ammonium algicides on the germicidal activity of chlorine. accurate determinations on the amounts of residual available chlorine in chlorine-quaternary mixtures could not be made by the usual chemical methods. this made it necessary to base all comparisons on the starting concentrations of available chlor ...19674965942
