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 |

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 |

bacterial pollution indicators in the intestinal tract of freshwater fish. | a study was made of the occurrence, distribution, and persistence of coliforms, fecal coliforms, and fecal streptococci in the intestinal tract of freshwater fish. a total of 132 fish representing 14 different species were used in various phases of these experiments. examination of the intestinal contents of 78 fish from moderately polluted sections of the little miami river indicated that fecal coliform densities were lowest in bluegills (less than 20 per gram) and highest in catfish (1,090,000 ... | 1966 | 6008184 |
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 ... | 1967 | 6077418 |
streptococci with dual antigen specificity for lancefield groups d and g. | streptococci have been isolated which may be identified in serological tests as belonging to lancefield group g, but in fact belong to group d. twenty-two cultures with this property were obtained from four countries; they included streptococcus bovis and streptococcus durans as well as streptococcus faecalis. selected strains were studied in serological tests and cross-absorption procedures, in which it was found that the group g reaction given by these isolates is due to an epitope with at lea ... | 1984 | 6084598 |
the in vitro antimicrobial activity of desacetylcefotaxime compared to other related beta-lactams. | like all other cephalosporins that contain an acetyl side chain in the 3' position, cefotaxime (ctx) is partially desacetylated in vivo. desacetylcefotaxime (des-ctx) possesses a broad antimicrobial spectrum and high beta-lactamase stability. with the exception of pseudomonas aeruginosa, morganella morganii, bacteroides fragilis, and staphylococcus aureus, most strains of other species tested usually had mean mics of des-ctx lower than 1 microgram/ml. its activity is generally lower than that of ... | 1984 | 6086214 |
cefotaxime and desacetylcefotaxime: an example of advantageous antimicrobial metabolism. | although the antibacterial activity of desacetylcefotaxime (des-ctx), the principal metabolite of cefotaxime (ctx), is eightfold lower than cefotaxime, the metabolite inhibits many b-lactamase-producing enterobacteriaceae and unusual pseudomonas species resistant to agents such as cefamandole, cefoxitin, and cefoperazone. des-ctx is more stable than ctx to attack by beta-lactamases of some species such as bacteroides fragilis, proteus vulgaris, and the k-1 enzyme of enterobacter-klebsiella. des- ... | 1984 | 6086215 |
hemolysin of streptococcus faecalis subspecies zymogenes contributes to virulence in mice. | the conjugative plasmid pad1 (56.7 kilobases) in streptococcus faecalis confers hemolysin-bacteriocin (hly-bcn) expression and a mating response to the sex pheromone cad1 excreted by recipient cells. we examined the contribution of hemolysin to pathogenicity in intraperitoneally infected mice by using tn916 and tn917 insertion mutants altered in hemolysin expression. strains exhibiting the normal hemolysin phenotype were significantly more virulent than the nonhemolytic insertion mutants. a muta ... | 1984 | 6086531 |
