| pleomorphism and pleobiosis of bacillus bifidus communis. | from the foregoing experiments, the conclusion may be drawn that b. bifidus communis of tissier has an aerobic phase, in which it resembles b. mesentericus fuscus. numerous intermediate phases can occur between these two extremes; and their morphological and biological variabilities demand the utmost attention in order to interpret more intelligently the various phases of a given organism, constantly found in the stools of sucklings, and to avoid the artificial creation of two or more organisms ... | 1910 | 19867322 |
| the influence of milk feeding on mortality and growth, and on the character of the intestinal flora. | throughout the investigations upon which a large part of this paper is based the favorable influence of milk feeding on mortality and growth was most apparent. mortality from all causes was frequently reduced to at least one-half of what obtained among the chicks that received no milk, while the milk-fed chicks in some experiments gained twice as much in weight as those that were without this article of diet. although the influence of milk feeding was less pronounced on the mortality of chicks t ... | 1915 | 19867878 |
| the intestinal flora in mouse typhoid infection. | the normal flora of laboratory mice at the rockefeller institute, fed on a bread and milk diet, was determined. bacillus acidophilus and bacillus bifidus outnumber the bacillus coli, bacillus acidi lactici, and bacillus coli communior group about twenty-five to one. white and yellow cocci which may or may not liquefy gelatin are occasionally noted; spirochetal and vibrio forms and yeasts are usually seen in stained preparations. this flora does not change when mice are artificially infected per ... | 1923 | 19868710 |

| effects of growth conditions on the lipid composition of bifidobacterium bifidum subsp. pennsylvanicum. | lipid-phosphorus and lipid-galactose content and phospholipid and fatty acid composition of bifidobacterium bifidum subsp. pennsylvanicum were examined under a wide variety of growth conditions. cells from 29-c cultures contained less lipid-phosphorus than did cells from 37-c cultures, but their lipid-galactose content and phospholipid composition did not differ. at both temperatures, the growth phase influenced the lipid composition similarly. phosphate, mg2+ and k+ concentrations in the medium ... | 1977 | 596859 |
| effects of growth conditions on the ion composition of bifidobacterium bifidum subsp. pennsylvanicum. | the cation content of bifidobacterium bifidum subsp. pennsylvanicum was markedly influenced by the washing procedure of the cells, by the growth phase and the temperature, and by the composition of the culture medium. optimal retention of cations was achieved by washing with 0.25 m mgcl2 at 20c. the intracellular na+ concentration rose during growth in normal medium to a constant value in the stationary phase, the k+ concentration rose in the exponential phase, but fell in the stationary phase. ... | 1977 | 596860 |

| presence of a single enzyme catalyzing the pyrophosphorolysis of udp-glucose and udp-galactose in bifidobacterium bifidum. | the enzyme preparation catalyzing the pyrophosphorolyses of udp-glucose and udpgalactose almost at the same rate was purified about 900-fold from bifidobacterium bifidum grown on glucose medium. the two activities were always associated with each other, and their activity ratio was always constant throughout the purification steps. the final preparations was revealed homogeneous by polyacrylamide gel electrophoresis in the presence and absence of sodium dodecyl sulfate. there was no significant ... | 1978 | 718964 |
| effects of antibiotics on the cation composition of bifidobacterium bifidum subspecies pennsylvanicum. | cell wall-inhibitory antibiotics caused a marked reduction of intracellular k+ and a small increase of na+, together resulting in a decline of intracellular cation content. chloramphenicol and tetracycline increased intracellular k+ but actinomycin decreased both na+ and k+ content. the release and uptake of 86rb+ were similarly affected by the antibiotics as the k+ content. the osmotic resistance of the protoplasts isolated from antibiotic-treated cells was apparently increased by inhibitors of ... | 1978 | 755153 |
| interactions between bifidobacterium bifidum n4 and escherichia coli k-12 in their mixed cultures. | the interactions between bifidobacterium bifidum n4 (b. bifidum) and escherichia coli k-12 (e. coli) were investigated in their mixed cultures. under conditions in which both bacteria grew well in their pure culture, b. bifidum inhibited the growth of e. coli even when the latter was inoculated at 10(4)-fold and preincubated for 41 hr. the inhibition in the mixed cultures appeared when the ph values were reduced below 4.6. when the lowering of ph was prevented by the addition of naoh, no inhibit ... | 1978 | 37291 |
| lipoquinones of some spore-forming rods, lactic-acid bacteria and actinomycetes. | the respiratory quinones of 73 strains of gram-positive bacteria including spore-forming rods, lactic-acid bacteria and actinomyctes were examined. menaquinones with seven isoprenoid units (mk-7) were the main quinone type found in representatives of the genus bacillus and in sporolactobacillus inulinus. however, a strain of b. thuringiensis produced mk-8 in addition to mk-7, and strains of b. lentus and b. pantothenticus appeared to produce mk-9 and mk-8, respectively, with no mk-7. in the clos ... | 1979 | 119033 |
| [antagonistic interrelationships of bifidobacterium bifidum i proteus vulgaris in vitro in the digestive tract of gnotobiotic chicks]. | the antagonistic relations between bacterium bifidum, strain i/850 phi, and proteus vulgaris, strain f-30, were studied. these organisms, when introduced together in equal doses into the digestive tract of gnotobiotic chickens in a single administration, were shown to create certain ecological correlations in various organs with the prevalence of bifidobacteria which exerted no negative influence on proteus vulgaris. the additional daily administration of bifidobacteria for 3 days running in dos ... | 1979 | 382712 |
| purification and properties of udp-glucose (udp-galactose) pyrophosphorylase from bifidobacterium bifidum. | an enzyme having both udp-glucose (udp-glc) and udp-galactose (udp-gal) pyrophosphorylase activities was purified to homogeneity from bifidobacterium bifidum. the molecular weight of the enzyme was about 200,000 and it appeared to be composed of four identical subunits. the purified enzyme showed almost the same reactivity towards udp-glc and udp-gal, and showed about 10% of this activity towards udp-xylose at 8 mm. the enzyme required magnesium ions for maximum activity. the apparent equilibriu ... | 1979 | 500588 |
