| incorporation of radioactive macromolecular precursors into intact cells and osmotically stabilized "protoplasts" of streptococcus faecalis. | growing "protoplasts" of streptococcus faecalis were shown to incorporate newly administered radioactive precursors in the same manner as growing intact streptococci. no observable differences could be found between the size of the leucine precursor pools of the two cultures. the extent of turnover of protein and ribonucleic acid in both "protoplast" and streptococcal cultures appeared to be identical. finally, the absolute rate of macromolecular biosynthesis was found to be equivalent whether d ... | 1971 | 5003181 |
| caffeic acid metabolism by bacteria of the human gastrointestinal tract. | the metabolism of caffeic acid, previously shown to be carried out by the intestinal microbiota of man and experimental animals, has now been examined in a number of bacteria isolated from human feces. it has been found that of the 12 organisms isolated none has the ability to catalyze more than one reaction of the series leading from caffeic acid to either m-hydroxyphenylpropionic acid or 4-ethylcatechol. | 1971 | 5003182 |

| pteroylglutamate derivatives in pisum sativum l. biosynthesis of cotyledonary tetrahydropteroylglutamates during germination. | 1. the concentrations of pteroylglutamate derivatives in the cotyledons of pea (pisum sativum l.) seedlings were determined by microbiological assay by using lactobacillus casei (a.t.c.c. 7469), streptococcus faecalis (a.t.c.c. 8043) and pediococcus cerevisiae (a.t.c.c. 8081). during germination the pteroylglutamate content of the cotyledons increased rapidly from 0.2mug/g dry wt. to 4.0mug/g dry wt., the maximum values being reached approx. 120h after imbibition. 2. approx. 50% of the pteroylgl ... | 1971 | 5003530 |

| studies on the absorption and metabolism of folic acid. i. folate absorption in the dog after exposure of isolated intestinal segments to synthetic pteroylpolyglutamates of various chain lengths. | folic acid absorption was studied in anesthetized dogs by determining the amount and chemical nature of folate in venous blood emerging from isolated intestinal segments containing free folic acid and/or pteroylpolyglutamates of a known chain length. chromatographically pure test materials placed in the lumen were prepared by unambiguous solid phase synthetic methods. this synthetic procedure not only yields compounds of known structure, it also provides a means by which glutamic acid residues a ... | 1971 | 5000560 |

| chromomycin a 3 , an antitumor antibiotic: tissue distribution studies in mice as measured by microbial assay. | a microbiological assay has been developed for chromomycin a(3), an antitumor antibiotic showing promise in human trials. the assay bacterium is a derived strain of streptococcus faecalis resistant to methotrexate. studies with mice revealed that relatively high concentrations of this antibiotic were maintained in the blood, kidneys, and liver of mice after a single-dose intraperitoneal injection of the drug. | 1971 | 5000865 |

| detection of relationships between streptococcus faecalis and lactobacillus casei by immunological studies with two forms of malic enzyme. | antisera prepared against two isologous malic enzymes from lactobacillus casei strains 64h and m40 were used to survey and categorize the various malic enzymes found within this diverse species. in addition to detecting three major antigenic variants of malic enzyme within this group, both antisera readily reacted with streptococcus faecalis malic enzyme. the cross-reactions between the l. casei malic enzyme antisera and the s. faecalis malic enzyme indicated that these iso-functional enzymes fo ... | 1971 | 5001196 |

| studies on antibiotic syngerism against enterococci. ii. effect of various antibiotics on the uptake of 14 c-labeled streptomycin by enterococci. | the mechanism by which agents that inhibit bacterial cell wall synthesis produce a synergistic effect against enterococci when combined with aminoglycoside antibiotics has not been elucidated. using (14)c-labeled streptomycin, it could be shown that uptake of this aminoglycoside antibiotic was markedly enhanced in enterococci growing in the presence of penicillin or other agents which inhibit the synthesis of bacterial cell walls. there was no enhancement of streptomycin uptake when the cells we ... | 1971 | 5001959 |

| differential action of a streptococcal bacteriocin on mycoplasmas and microbial l-forms. | bacteriocin activity of streptococcus faecalis var. zymogenes was tested against a variety of bacteria, l-forms, and mycoplasmas. both a partially purified liquid preparation and a colony overlay technique were used. other s. faecalis strains were the only bacteria whose growth was inhibited. the liquid preparation inhibited growth of all but three of the tested l-forms (whether derived from gram-positive or gram-negative bacteria), and two of these exceptional organisms were inhibited when the ... | 1971 | 5005294 |
| media exchange method for demonstrating killing of l-phase variants in solid media by normal human serum. | normal human serum has been shown to kill l-phase variants in a fluid system by the action of antibody plus complement. previous studies, however, failed to demonstrate such killing in solid media. this failure probably resulted from inhibition of complement by medium components such as agar and nacl. a method was developed which circumvents the problems of the anticomplementary properties of agar media and the requirement of some l-phase variants for concentrations of salt that inhibit compleme ... | 1971 | 5005296 |
| influence of antibiotics or certain intestinal bacteria on orally administered candida albicans in germ-free and conventional mice. | candida albicans, administered by gastric intubation, persisted in the gastrointestinal tract of gnotobiotic mice for long periods but was eliminated within a relatively short period of time in pathogen-free mice. oxytetracycline administered by mouth had no reproducible effect on the persistence of c. albicans in the gastrointestinal tract of either germ-free or pathogen-free mice. prolonged administration of streptomycin extended the time that c. albicans could be recovered from feces of patho ... | 1971 | 5005314 |

| folates in plasma and bile of man after feeding folic acid--3h and 5-formyltetrahydrofolate (folinic acid). | during the 1st hr after feeding folic acid-(3)h ((3)h-pteglu) to fasting human volunteers, plasma s. faecalis and (3)h activity were elevated to an equivalent degree, whereas after this, the (3)h activity exceeded s. faecalis activity, which suggests gradual conversion of folic acid-(3)h to methyltetrahydrofolate-(3)h (5-ch(3)h(4) pteglu). the increase of l. casei activity exceeded the increase of s. faecalis and (3)h activity, which is consistent with flushing of endogenous methyltetrahydrofola ... | 1971 | 4992993 |
| injury of bacteria by sanitizers. | injury of test cultures was quantitated by differences in colony counts obtained with a complete medium and those obtained on conventional selective media. staphylococcus aureus, streptococcus faecalis, and several strains of escherichia coli were injured when exposed to the quaternary ammonium compound methylalkyltrimethyl ammonium chloride. representative hypochlorite sanitizers also caused injury of e. coli ml30. sanitizer concentration appeared to be the main factor in the cause of death and ... | 1971 | 4993231 |

| mechanism of resistance to antibiotic synergism in enterococci. | enterococci exhibit two types of resistance to streptomycin. moderately high-level resistance is observed in most naturally occurring strains and can be overcome by simultaneous exposure to penicillin. in addition, very high-level resistance is found in those strains against which penicillin plus streptomycin fail to produce synergism in vitro. to study the mechanism of streptomycin resistance in enterococci, ribosomes from a wild-type strain and from a highly streptomycin-resistant mutant were ... | 1971 | 4994038 |

| comparative biochemical and immunological study of malic enzyme from two species of lactic acid bacteria: evolutionary implications. | representatives of both streptococcus faecalis and lactobacillus casei produce isofunctional malic enzymes. all 10 strains of s. faecalis tested could be induced to synthesize malic enzyme and readily adapted to growth on malate. although 17 of 21 l. casei strains could be induced to produce malic enzyme, only 9 of 14 strains tested grew at the expense of malate. a comparison of catalytic and regulatory properties suggested that the malic enzymes from s. faecalis and l. casei were very similar. ... | 1971 | 4323962 |
