antimalarial activity of tetrahydrohomopteroic acid.tetrahydrohomopteroic acid, an analog of tetrahydrofolic acid, shows antimalarial activity against plasmodium cynomolgi and a pyrimethamine-resistant variant of this organism.19674960875
fumarate reductase activity of streptococcus faecalis.some characteristics of a fumarate reductase from streptococcus faecalis are described. the enzyme had a ph optimum of 7.4; optimal activity was observed when the ionic strength of the phosphate buffer was adjusted to 0.088. the k(m) value of the enzyme for reduced flavin mononucleotide was 2 x 10(-4)m as determined with a 26-fold preparation. in addition to fumarate, the enzyme reduced maleate and mesaconate. no succinate dehydrogenase activity was detected, but succinate did act as an inhibito ...19674960892

fat absorption from the small intestine of gnotobiotic chicks.the small intestine of 3-week-old gnotobiotic chicks was divided into five equal segments for analysis. since it has been found that most fat absorption occurs in the third and fourth segments, they were selected for study. the major fatty acids in the diet and the feces of chicks were palmitic, stearic, oleic, and linoleic acids. consequently, these fatty acids were selected for quantitative analyses in the absorption studies. germ-free chicks were contaminated at 7 days of age with bacteria is ...19676077418

activities of arginine dihydrolase and phosphatase in streptococcus faecalis and streptococcus faecium.strains of streptococcus faecalis and s. faecium are known to produce ammonia from arginine, but only s. faecalis couples the adenosine triphosphate (atp) produced through the arginine dihydrolase pathway to growth processes. the specific activities of the arginine dihydrolase enzymes were found to be much lower in s. faecium (0.01 to 0.10) than in s. faecalis (0.24 to 1.60). phosphatase activities in both strains were similar (up to 0.11), but equaled or exceeded the activities of the arginine ...19684300895
site in cell-free protein synthesis sensitive to diphtheria toxin.the effects of diphtheria toxin on cell-free protein synthesis in a bacterial system, and preparations obtained from animals that were sensitive and resistant to toxin were examined. in the presence of nicotinamide adenine dinucleotide (nad), toxin inhibited the incorporation of amino acids by endogenous and synthetic polynucleotides in both rat liver and guinea pig liver cell-free systems that were exposed to 6 lf units per ml of toxin. a cell-free system derived from streptococcus faecalis was ...19684301046
modified biochemical tests for characterization of l-phase variants of bacteria.biochemical capabilities of bacterial and l-phase organisms of 15 bacterial strains were examined by using a variety of modified routine diagnostic biochemical tests. the results demonstrated that 13 of the tests examined were suitable for use with l-phase variants, that l-phase variants and revertant bacterial phase organisms retained diagnostically significant capabilities of the respective bacterial or l-phase organisms from which they were derived, and that the 13 biochemical tests could be ...19684302280
molar growth yields as evidence for oxidative phosphorylation in streptococcus faecalis strain 10cl.during the aerobic growth of streptococcus faecalis strain 10c1, with limiting levels of glucose as the substrate, a molar growth yield (y) of 58.2 g (dry weight) per mole of glucose was obtained. under these conditions of growth, glucose was dissimilated primarily to acetate and co(2). the incorporation of (14)c-glucose into cell material was no greater under aerobic conditions than during anaerobic growth. assuming an adenosine triphosphate coefficient of 10.5, the aerobic y cannot be explaine ...19684302299

inhibition of membrane transport in streptococcus faecalis by uncouplers of oxidative phosphorylation and its relationship to proton conduction.we studied the effect of compounds that uncouple oxidative phosphorylation on membrane function in streptoccocus faecalis, an organism which relies upon glycolysis for the generation of metabolic energy. at low concentrations (ranging from 10(-7) to 10(-4)m), tetrachlorosalicylanilide, tetramethyldipicrylamine, carbonylcyanide m-chlorophenylhydrazone, pentachlorophenol, and dicoumarol strongly inhibited energy-dependent transport of rubidium, phosphate, and certain amino acids. however, these co ...19684177737

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

effect of salt concentration in the recovery medium on heat-injured streptococcus faecalis.properties relating to the recovery of three heat-injured strains of streptococcus faecalis were studied. all strains were cultured in all purpose plus tween broth (apt) at 30 c for 24 hr before being subjected to heat in fresh apt broth. apt recovery medium containing various added amounts of nacl, kcl, mgcl(2), or kcl and mgcl(2) was used to assess the effect of salts on the recovery of thermally injured s. faecalis. it was evident that, upon exposure to heat, s. faecalis cells became sensitiv ...19684968964

rapid and sensitive detection of bacteria by gas chromatography.a gas chromatograph fitted with electron capture and flame ionization detectors was employed for the rapid detection of bacteria by analysis for their metabolic products. the presence of proteus vulgaris, streptococcus faecalis, s. liquefaciens, escherichia coli b, bacillus cereus, and b. popilliae was detected in 2 to 4 hr in media inoculated with less than 10(4) cells per ml, whereas a 7- to 12-hr growth period was required for the detection of products formed in cultures of serratia marcescen ...19684967452

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

penicillin: effect on sodium and potassium transport in bacterial and protoplast forms of sterptococcus faecalis.streptococcus faecalis, incubated in osmotically stabiliz medium in the presence of 1000 units of penicillin per milliliter, accumulated rather than extruded sodium; they accumulated much less potassium than control cells did. these changes were not due to binding of sodium by cell-wall fragments of cells treated with penicillin. because penicillin had no effect on cation concentrations in stable protoplasts and nongrowing bacterial cells, this effect appeared to be related to the production of ...19684975004
