| the lethal effect of tryptone-soya broth. | overnight cultures of v. cholerae, v. el tor, non-cholera vibrio, and streptococcus pneumoniae in tryptone-soya broth (with 5% blood added for the last-named) failed to grow on subculture despite visible growth in all tubes. viable counts and ph determinations of overnight cultures of various species in tryptone-soya broth, brain-heart infusion broth, and lab-lemco peptone broth show that death in tryptone-soya broth is associated with the drop in ph resulting from fermentation of glucose in the ... | 1972 | 4622999 |

| osmotic stability and sodium and potassium content of l-forms of streptococcus faecalis. | a stable l-form of streptococcus faecalis (t(53)) was transferred in media containing decreasing concentrations of sucrose until it grew in medium without added osmotic stabilizer. this l-form (designated t(53i)) was compared with t(53) from which it was derived. the survival of these two l-forms suspended at different osmolalities showed that maximal survival for t(53i) was 350 to 400 milliosmolal and for t(53) was 900 to 1,000 milliosmolal. both peaks were at the osmolality of their growth med ... | 1972 | 4623309 |

| revival and subsequent isolation of heat-injured bacteria by a membrane filter technique. | cultures containing mixed flora from raw milk were heated at 62.8 c for 15, 20, 25, and 30 min. dilutions were filtered through membrane filters, and the filters were incubated on trypticase soy broth (tsb) and on tsb plus nacl (tsbs). the tsb count indicated the total population which survived heating and included injured and uninjured cells. the colonies on tsbs indicated the uninjured cells and were marked by perforating the membrane near the colony. this membrane was then transferred to fres ... | 1972 | 4624208 |
| tolerance of staphylococcal thermonuclease to stress. | remarkable tolerance to prolonged heating, prolonged storage, and bacterial proliferation was exhibited by staphylococcal thermonuclease in foods and broth. a purified enzyme preparation added to brain heart infusion broth was unaffected by the growth of five bacterial species. minimal inactivation was effected by bacillus subtilis. optimal growth of streptococcus faecalis var. liquifaciens caused extensive inactivation of thermonuclease. however, storage at room temperature or the addition of 5 ... | 1972 | 4624218 |

| trimethoprim-sulphamethoxazole in urinary tract infection due to streptococcus faecalis. | in-vitro sensitivities were performed on 140 specimens of urine which grew streptococcus faecalis of more than 100 000 organisms/ml between march 1970 and february 1971. although the combination of trimethoprim and sulphamethoxazole definitely appeared to be more effective than sulphonamide alone and as effective as ampicillin, its use for more than two weeks in 14 cases of uncomplicated urinary tract infection due to streptococcus faecalis led to development of resistance. as in these cases org ... | 1972 | 4625437 |

| the combination of trimethoprim and sulfamethoxazole in the treatment of urinary tract infection. | in a series of 52 patients the combination of trimethoprim and sulfamethoxazole was used for the treatment of urinary tract infection and the results are analyzed with respect to the clinical diagnosis and bacterial etiology. there was complete agreement between in vitro sensitivity and clinical response except in the case of one strain of streptococcus fecalis. the combination of drugs was effective against some bacterial strains which were resistant to the commonly used antimicrobial agents. | 1972 | 4626767 |
| evaluation and standardization of an agglutination test for human listeriosis. | human sera from patients with culturally confirmed listeriosis were tested for immunoglobulin m (igm) and immunoglobulin g (igg) agglutinating antibodies with trypsinized antigens of listeria monocytogenes, streptococcus faecalis, and staphylococcus aureus. the response of humans to listeria infections is mainly igm rather than igg as found in animals. the antigens prepared from l. monocytogenes serotypes 1a, 1b, 2, 4b, and 4d were evaluated for specificity with normal sera, sera from patients w ... | 1972 | 4626902 |

| observations on folate absorption with particular reference to folate polyglutamate and possible inhibitors to its absorption. | a test system for detection of inhibitors to the enzyme which removes the glutamic acid peptide chain from folate polyglutamates (folate conjugase) is described. this utilizes the reaction between plasma conjugase and the folate polyglutamate in red blood cell haemolysate. diphenylhydantoin and yeast extracts did not inhibit plasma conjugase. the better absorption of monoglutamate forms of folate as compared to polyglutamate forms was confirmed. polyglutamates were absorbed normally by patients ... | 1972 | 4627052 |

| improvement of microbial assays of vitamins. | a method for the improvement of microbial assays of vitamins, which involves the addition of a surfactant to the incubated test, was developed. this surfactant tends to eliminate bacterial clumping, giving a uniform suspension of single cells, thereby making the turbidity readings less erratic and the actual assay standard curves more closely related to the desired theoretical curve. | 1972 | 4627232 |

| folate metabolism in streptococcus faecalis. | the possibility that the inability of streptococcus faecalis to utilize 5-methyltetrahydropteroylglutamate or pteroyltriglutamate might be due to permeability was investigated. whereas the former was taken up by s. faecalis cells growing on pteroylglutamic acid, the latter was not. no subsequent conversion of the 5-methyltetrahydropteroylglutamate took place and accumulation, which was against a considerable concentration gradient, was inhibited by fluoride. it would thus appear to be an active ... | 1972 | 4627689 |
| the lipid-teichoic acid complex in the cytoplasmic membrane of streptococcus faecalis n.c.i.b. 8191. | 1. a lipid-teichoic acid complex was isolated from streptococcus faecalis n.c.i.b. 8191. the covalent nature of the linkage between teichoic acid and lipid was established. 2. the complex exhibits macromolecular properties in solution, and ultracentrifugation studies show that these are due to micelle formation. 3. from chemical studies it is concluded that the teichoic acid is a poly(glycerol phosphate) in which some of the glycerol hydroxyl groups possess kojibiosyl [2-o-alpha-d-glucopyranosyl ... | 1972 | 4627730 |
| quantitative sputum culture as a means of excluding false positive reports in the routine microbiology laboratory. | a relatively simple technique for sputum homogenization and dilution is described. results show that this technique is reliable for isolation and quantitative culture of organisms from cases of chest infection. the technique has resulted in significant reduction in false positive reports, particularly when a system of interpretative reporting is utilized based on 10(7) organisms per millilitre of sputum being accepted as evidence of significant infection. | 1972 | 4627746 |

| 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 |
