| extrusion of sodium and hydrogen ions as the primary process in potassium ion accumulation by streptococcus faecalis. | glycolyzing cells of streptococcus faecalis accumulate k(+) with concurrent extrusion of equivalent amounts of h(+) and na(+). an attempt was made to clarify the retionship between the movements of na(+) and k(+). sodium was displaced from cells glycolyzing in the presence of ammonia, diethylamine, tris(hydroxymethyl)aminomethane, and other nitrogenous cations; by contrast, k(+) was completely retained. accumulation of k(+) by heterologous exchange for na(+) was not inhibited by antibiotics whic ... | 1970 | 4983644 |
| model for cell wall growth of streptococcus faecalis. | in exponentially growing and dividing cells of streptococcus faecalis, it is proposed that the leading edge of the annularly closing cross wall is the point of extension for both cross wall and peripheral wall. peripheral wall extension is thought to be produced by the separation or splitting of the cross wall at its junction with peripheral wall. this results in the pushing of the equatorial wall bands, found on s. faecalis walls, to subsequatorial positions. these bands therefore mark the sepa ... | 1970 | 4984078 |

| early changes in the ultrastructure of streptococcus faecalis after amino acid starvation. | thin sections of streptococcus faecalis (atcc 9790) starved of one essential amino acid (threonine or valine) initially show rapid increases in (i) cell wall thickness, (ii) the apparent size of the central nucleoid region, and (iii) mesosomal membranes. the most rapid increases in all three variables occurred during the first 1 to 2 hr of starvation. after this initial period, the rates progressively decreased over the 20-hr observation period. during threonine starvation, the mesosomal membran ... | 1970 | 4987306 |

| in-vitro comparison of erythromycin, lincomycin, and clindamycin. | the in-vitro antibacterial activities of erythromycin, lincomycin, and clindamycin, a new derivative of lincomycin, were compared. clindamycin was always more active than lincomycin, and was either as active as erythromycin or more so against betahaemolytic streptococci, streptococcus viridans, str. pneumoniae, and erythromycin-sensitive staphylococcus aureus. it was also fully active against most erythromycin-resistant strains of staph. aureus. on the other hand, it was somewhat less active tha ... | 1970 | 4988120 |
| relationship between the location of autolysin, cell wall synthesis, and the development of resistance to cellular autolysis in streptococcus faecalis after inhibition of protein synthesis. | ten minutes after inhibition of protein synthesis with chloramphenicol (cap) the ability of cells of streptococcus faecalis (atcc 9790) to autolyze decreased to less than 20% of the rate for exponential-phase cells. after threonine exhaustion, the time for a 50% drop in the rate of cellular autolysis was about 20 min. these rapid increases in resistance to cellular autolysis could not be accounted for by: (i) the relatively slow and small overall decrease in susceptibility of isolated cell walls ... | 1970 | 4988243 |
| site of initiation of cellular autolysis in streptococcus faecalis as seen by electron microscopy. | low concentrations of glutaraldehyde (0.1% or higher) blocked cellular and wall autolysis. the site of autolytic activity was studied by allowing cell autolysis to proceed for very short periods (0 to 15 min) before addition of glutaraldehyde. electron microscopy of ultrathin sections showed that the primary site of autolytic activity was the leading edge of the nascent cross wall. the base of the cross wall seemed more resistant than the tip. evidence supporting the involvement of autolysin act ... | 1970 | 4988247 |

| enhancement of glutamic-pyruvic transaminase activity in leptospirae by addition of rabbit serum. | glutamic-pyruvic transaminase (gpt) in leptospirae was shown to have an optimal temperature of 30 c and ph 8.0. it was activated by cofactor pyridoxal phosphate, similar to gpt from other sources. however, gpt in all leptospirae, such as leptospira canicola, l. icterohaemorrhagiae, l. autumnalis, and l. biflexa, evidently had less activity even when pyridoxal phosphate was present, in comparison with the cultivable spirochete reiter treponeme and streptococcus faecalis. the low level of activity ... | 1970 | 16557719 |
| pyelonephritis xi. effect of growth phase of streptococcus faecalis on serum susceptibility and virulence. | rapidly growing streptococcus faecalis was found to be markedly susceptible to the bactericidal activity of normal rat and rabbit sera, whereas stationary-phase organisms were resistant. in contrast, human serum killed neither phase organism. further, human serum was found to interfere with killing by rabbit serum. the serosusceptible, rapidly growing organisms were less virulent than the seroresistant, stationary-phase organisms. this was tested by production of pyelonephritis in the rat after ... | 1970 | 16557772 |
| responses of the peyer's patches in germ-free mice to antigenic stimulation. | lymph nodes, spleens, and peyer's patches of germ-free mice are relatively inactive. the tissues are small and contain rare, small, indistinct, germinal zones. when exposed to antigenic stimuli (salmonella paratyphi a and lymphocytic choriomeningitis virus), the tissues become larger and germinal zones appear coincident with antibodies in the blood. the peyer's patches were activated if antigen was absorbed from the intestinal lumen into the circulation but not if the antigen was administered pa ... | 1970 | 16557807 |
| lysis of grouped and ungrouped streptococci by lysozyme. | thirty strains of streptococci were tested for lysis with lysozyme, and 29 of these could be lysed by the following method: (i) suspension of the cells to a klett reading of 200 units (no. 42 filter) in 0.01 m tris(hydroxymethyl)aminomethane buffer, ph 8.2, after washing twice with the buffer; (ii) addition of lysozyme to a final concentration of 250 mug/ml with incubation for 60 min at 37 c; (iii) addition of sodium lauryl sulfate (sls) to a final concentration of 0.2% and incubation up to an a ... | 1970 | 16557878 |
| membrane mg-(ca)-activated adenosine triphosphatase of escherichia coli: characterization in the membrane-bound and solubilized states. | the membrane-associated mg(2+)-activated and ca(2+)-activated adenosine 5'-triphosphatase (ec 3.6.1.3; atpase) activities of escherichia coli were further characterized. the degree of inhibition of membrane-bound mg(2+)-(ca(2+))-atpase by a series of anions (i.e., sodium salts of nitrate, iodide, chloride, and acetate) was found to correlate with the relative chaotropic, or solubilizing, effectiveness of these anions. the enzyme was solubilized from washed membrane ghosts by treatment with 0.04% ... | 1970 | 16559094 |
| urinary tract pathogens-sensitivity to trimethoprim/sulphamethoxazole. | abstract the sensitivity to sulphamethizole, sulphamethoxazole (sm), trimethoprim (tmp) and the combination sm/tmp of freshly isolated urinary tract pathogens from hospital patients was studied. out of 798 strains tested primarily, 47% were found to be fully sensitive to sulphamethizole (tablet method), and 81% fully sensitive to the sm/tmp combination (disk method). out of 423 strains with reduced sensitivity to sulphamethizole, 65% were fully sensitive to sm/tmp. out of 391 strains tested seco ... | 1970 | 25607580 |

| mechanism for regulating the distribution of glucose carbon between the embden-meyerhof and hexose-monophosphate pathways in streptococcus faecalis. | glucose-adapted streptococcus faecalis produced little if any (14)co(2) from glucose-1-(14)c, although high levels of glucose-6-phosphate dehydrogenase (ec 1.1.1.49) and 6-phosphogluconate dehydrogenase (ec 1.1.1.44) were detected in cell-free extracts. metabolism of glucose through the oxidative portion of the hexose-monophosphate pathway was shown to be regulated in this organism by the specific inhibitory interaction of the embden-meyerhof intermediate, fructose-1, 6-diphosphate (fdp), with 6 ... | 1971 | 4396792 |

| 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 ... | 1971 | 4398532 |
| quantitative studies on the salivary flora. | in a quantitative bacteriological study of the salivary flora from 50 children the following aerobic organisms were identified and enumerated: alpha-haemolytic streptococci, beta-haemolytic streptococci, streptococcus faecalis, pneumococci, staphylococcus aureus, staph. albus and staph. citreus, neisseria spp, n. meningitidis, corynebacteria, aerobic lactobacilli, b. subtilis, h. influenzae, coliform organisms, and candida spp. many of the known potentially pathogenic members were present in lar ... | 1971 | 4399776 |

| effects of essential amino acid starvation in streptococcus faecalis: structural change in the 50s ribosomal subunit. | the 50s ribosomal subunits obtained from exponential-phase and valine-limited cultures of streptococcus faecalis 9790 differed in protein content. approximately 35% of the valine-limited subunits showed protein losses when analyzed by cscl density centrifugation after formaldehyde fixation. results of density gradient analysis and of acrylamide gel electrophoresis localized the protein to a "split" subunit fraction. no differences could be detected in the protein contents of 30s subunits from ex ... | 1971 | 4925120 |
| pressure sensitivity of streptococcal growth in relation to catabolism. | the sensitivity of streptococcus faecalis growth to hydrostatic pressures ranging up to 550 atm was found to depend on the source of adenosine triphosphate for growth. barotolerance of cultures growing in a complex medium with ribose as major catabolite appeared to be determined primarily by the pressure sensitivity of ribose-degrading enzymes. apparent activation volumes for growth were nearly identical to those for lactate production from ribose, and yield coefficients per mole of ribose degra ... | 1971 | 4925191 |
