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 bdello...

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.

Isolation and characterization of temperature-sensitive mutants of host-dependent Bdellovibrio bacteriovorus 109D.

A variety of temperature-sensitive mutants of host-dependent Bdellovibrio bacteriovorus 109D were selected after ethyl methane sulfonate mutagenesis. Mutants that demonstrated plaque-forming ability reversion frequencies of 10(-8) to 10(-9) were chosen for further study. Representatives of these mutants were then characterized by phase-contrast and electron microscopy, temperature-shifted one-s...

Bacteriol. 82:135-141. 1961.-A simplified procedure for direct isolation of phages for Bacillus subtilis from soil was developed. Phage enrichment was accomplished by growing streptomycin-resistant B. subtilis in medium previously inoc...

Isolation and characterization of bacteriophages for Neisseria.

Sixteen bacteriophages for several strains of Neisseria perflava were isolated from throat washings and lysogenic organisms. The phages are placed into five groups based on serological and host-range characteristics. Group I, host strain c r, has phages NI, N2, mutant N2C, N5, N6, and NI3. N I is virulent, all others temperate for the host. Plaque size is about 1.5 mm., the largest for Neisseri...
