| development of bdellophage vl-1 in parasitic and saprophytic bdellovibrios. | ultrastructure was correlated with growth kinetics of bdellophage vl-1 infecting host-dependent ("parasitic") bdellovibrio bacteriovorus 109j in its escherichia coli b host (the three-membered system), as well as in the host-independent ("saprophytic") derivative of the bdellovibrio. electron microscope observations showed the arrested growth of the phage-infected bdellovibrios, polar localization of the phage progeny, and stages in their release. present evidence indicates that bdellophage dna ... | 1973 | 4128380 |
| a growth initiation factor for host-independent derivatives of bdellovibrio bacteriovorus. | host-independent (h-i) derivatives of bdellovibrio bacteriovorus 109 davis could not be isolated when concentrated suspensions of host-dependent (h-d) cultures, washed free of spent medium, were plated on host-free media. however, h-i colonies did appear when spent broth was incorporated into the isolation medium, indicating the presence of a factor in the spent medium essential for the growth of h-i cells. this growth factor (gif) was also present in cell-free extracts of escherichia coli and a ... | 1973 | 4197902 |

| respiration of bdellovibrio bacteriovorus strain 109j and its energy substrates for intraperiplasmic growth. | measurements of oxidation rates, respiratory quotients (rq), and release of (14)co(2) from uniformly labeled substrates showed that glutamate, alpha-ketoglutarate, and synthetic and natural amino acid mixtures are oxidized by suspensions of bdellovibrio bacteriovorus strain 109j. the oxidation of these substrates largely suppress the endogenous respiration of the bdellovibrio cells and may or may not cause a small increase, 20 to 50%, in their rate of oxygen consumption. the failure of respired ... | 1973 | 4570779 |

| occurrence of phosphonosphingolipids in bdellovibrio bacteriovorus strain uki2. | the major phospholipids of two strains of bdellovibrio bacteriovorus were characterized. both strain uki1, which is obligately saprophytic, and strain uki2, which is facultatively parasitic, contained phosphatidylethanolamine and phosphatidylglycerol as their major glycerophosphatides. a branched, 15-carbon fatty acid is the major component of these alkali-labile lipids. absent from uki1 but present in uki2 were three alkali-stable lipids (compounds 8, 9, and 11) which appear to be phosphosphing ... | 1973 | 4752938 |

| three-membered parasitic system: a bacteriophage, bdellovibrio bacteriovorus, and escherichia coli. | two bacteriophages for bdellovibrio bacteriovorus were isolated. one of the phages (vl-1) was isolated on a host-independent bdellovibrio strain, and the other (vl-2) was isolated on a host-dependent strain. both phages grew on host-dependent as well as on host-independent bdellovibrio strains. the development of the phages in host-dependent bdellovibrios occurred only when the phage-infected bdellovibrios parasitized cells of other bacteria. in the absence of other bacteria, the phages adsorbed ... | 1972 | 4552554 |
| nonidentity of bdellovibrio bacteriovorus strains 109d and 109j. | two strains of bdellovibrio bacteriovorus, both designated as 109 in the literature, differ. they should be referred to as 109d and 109j to avoid further confusion. | 1972 | 4109891 |

| isolation and preliminary characterization of bacteriophages for bdellovibrio bacteriovorus. | ten bacteriophages that attack and lyse saprophytic strains of bdellovibrio bacteriovorus were isolated. morphological, serological, and host-range studies revealed that there were four different bdellovibrio phages present among the isolates. one of the phages lysed a strain of b. bacteriovorus that requires the presence of a suitable bacterial host for growth. the phage attached to the bdellovibrio cells in the absence of the bacterial host cells; lysis occurred only in the presence of host ce ... | 1972 | 4116140 |

| molecular heterogeneity of the bdellovibrios: evidence of two new species. | a systematic examination of a variety of isolates of the bacterial endoparasite bdellovibrio has revealed extensive molecular diversity. the quantity of deoxyribonucleic acid (dna) polynucleotide homology ranges from more than 90% among the isolates with dna containing 50 to 51% guanine plus cytosine (gc) to undetectable levels between the 43% gc and 51% gc isolates. the two isolates with low gc-containing dna (h-i bdellovibrio a3.12 and uki2) have only 16% dna homology. h-i bdellovibrio a3.12 a ... | 1972 | 4621626 |

| kinetics of deoxyribonucleic acid destruction and synthesis during growth of bdellovibrio bacteriovorus strain 109d on pseudomonas putida and escherichia coli. | during the growth of bdellovibrio bacteriovorus on pseudomonas putida or escherichia coli in either 10(-3)m tris(hydroxymethyl)aminomethane or in dilute nutrient broth, the host deoxyribonucleic acid (dna) was rapidly degraded, and by 30 to 60 min after the initiation of the bdellovibrio development cycle essentially all host dna became nonbandable in cscl gradients. at this stage the host dna degradation products were nondiffusable, and there was no appreciable pool of low-molecular-weight (col ... | 1972 | 4559819 |

| early host damage in the infection cycle of bdellovibrio bacteriovorus. | the effects of bdellovibrio infection on host permeability and respiration were investigated by measuring respiration rates and the rate of o-nitrophenyl-beta-d-galactopyranoside hydrolysis during the course of single infection cycles of bdellovibrio bacteriovorus strain 109 growing on escherichia coli ml 35 (lac i(-)z(+)y(-)). the data show that among the very early consequences of parasite attack on the host are an increase in permeability and a general disruption of respiratory activity of th ... | 1970 | 4908670 |
| isolation of a bacteriophage for bdellovibrio bacteriovorus. | a phage infective for bdellovibrio bacteriovorus was isolated. electron microscopy revealed that it is tail-less, has a hexagonal appearance and two distinct capsomere layers, and is 60 to 70 nm in size. the nucleic acid appears to be single-stranded deoxyribonucleic acid. this is the first report of the isolation of a phage infective for b. bacteriovorus. | 1970 | 4191817 |
| facultatively parasitic strain of bdellovibrio bacteriovorus. | a strain of bdellovibrio bacteriovorus (designated strain uki2) was isolated which was capable of growing either saprophytically in host-free medium or endoparasitically in escherichia coli b/r. it was quantitatively determined that each bdellovibrio could develop in solid medium to produce a colony, and 65% of the cells in a late exponential-phase culture were capable of inducing e. coli b/r spheroplasts. a photomicrographic sequence of single e. coli spheroplasts containing bdellovibrios demon ... | 1970 | 4908792 |
| ultrastructure and cell division of a facultatively parasitic strain of bdellovibrio bacteriovorus. | some aspects of cell development and division of bdellovibrio bacteriovorus strain uki2 were examined by use of electron microscopic techniques. under saprophytic and parasitic conditions of growth, the comma-shaped cells enlarge, elongate, and form helical filaments. the mechanism of division appears to consist of an asymmetrical constriction of the filamentous cell by the cytoplasmic membrane, accompanied by a breakdown of the outer layers of the cell wall in the division region. during regene ... | 1970 | 4908793 |

| structural properties and features of parasitic bdellovibrio bacteriovorus. | the structure of five parasitic strains of bdellovibrio bacteriovorus was studied by electron microscope after negative staining and in shadow-case and etched freeze-fractured preparations. special attention was paid to the cell wall and the flagellar sheath which is continuous with the wall or part of it. these structural components reveal distinct features which are induced by certain staining substances; they are exceedingly susceptible to disruption by physical treatments, and in old cells o ... | 1970 | 4099101 |
| bdellovibrio bacteriovorus parasitism in shigella species. | bdellovibrio bacteriovorus was capable of parasitizing shigella boydii, s. flexneri, and s. sonnei. the bdellovibrio was able to produce plaques on lawns consisting of heat-killed or ultraviolet-irradiated s. boydii. | 1970 | 16557841 |

| factors affecting the intracellular parasitic growth of bdellovibrio bacteriovorus developing within escherichia coli. | a procedure for one-step growth experiments on bdellovibrio bacteriovorus growing parasitically in escherichia coli b was developed. the resulting one-step growth curves showed that, under defined conditions at 30 c, each singly infected e. coli host cell, on the average, gave rise to 5.7 bdellovibrio cells. this value was confirmed by single-burst experiments and by microscopic observations. in the temperature range of 25 to 38 c, the average burst size and the duration of the latent period wer ... | 1969 | 4886299 |

| isolation and characterization of host-independent bdellovibrios. | a reliable method has been developed for the isolation of host-independent (h-i; i.e., "saprophytic") strains of bdellovibrio from host-dependent (h-d; i.e., "parasitic") cultures. the technique involves growing streptomycin-resistant (sm(r)) h-d cultures on streptomycin-susceptible (sm(8)) host cells. a lysate containing large numbers of the sm(r) h-d cells and some remaining sm(8) host cells is transferred to a selection medium which contains the antibiotic. the sm(8) host cells in the lysate ... | 1969 | 4901359 |
| deoxyribonucleic acid characterization of bdellovibrios. | the guanine plus cytosine (gc) content of the deoxyribonucleic acid (dna) of 11 isolates of host-dependent (h-d) bdellovibrios and 18 host-independent (h-i) derivatives was determined from thermal denaturation curves and buoyant densities in cscl. the h-d and respective h-i cultures have gc contents which are identical within the limits of experimental error. most cultures of bdellovibrio bacteriovorus, including the holotype culture, have 50.4 +/- 0.9 moles% gc in their dna; two bdellovibrio is ... | 1969 | 4901360 |
| interaction of bdellovibrio bacteriovorus and host bacteria. ii. intracellular growth and development of bdellovibrio bacteriovorus in liquid cultures. | the intracellular life cycle of bdellovibrio bacteriovorus 109 growing on escherichia coli in a dilute nutrient medium exhibits a period of constant infective titer while the parasite grows and elongates inside the host cell. this period is terminated after 2 to 4 hr, and the number of the plaque-forming units in the culture rises rapidly to as much as six times the initial titer. the growth pattern of bdellovibrio is similar with actively growing or resting host cells, or with host cells killed ... | 1969 | 4895842 |
