Morphology of Bacteriophage-Like Particles from Fusobacterium symbiosum

Presence of bacteriophage-like inhibitory particles in Escherichia coli.

Bacteriophage-like particles were found in the supernatant fluids of Escherichia coli O111a and O111:B(4). Caution is urged in the study of deoxyribonucleic acid synthesis and replication in these strains.

Incomplete bacteriophage-like particles in ultraviolet-irradiated haemophilus.

Incomplete phagelike particles were found in competent and incompetent cells of Haemophilus influenzae Rd (transformable) lysed after exposure to ultraviolet radiation.

Isolation of virus like particles from fecal material obtained from diarrheal calves

Genetic Recombinations Leading to Production of Active Bacteriophage from Ultraviolet Inactivated Bacteriophage Particles.

HE T potentialities of bacteriophage genetics have been revealed by the discovery of genetic recombinations among related phage particles infecting the same bacterial cell (DELBR~CK and BAILEY 1946). The complexities of these genetic systems have been further illustrated by the work of HERSHEY and ROTMAN (1948) on a number of different genetic determinants involved in the determination of the a...

Organization of bacteriophage tail-like particles in cells of Chromobacterium violaceum.

A strain of Chromobacterium violaceum has been isolated which produces bacteriophage tail-like particles in high numbers. The extracellular morphology and the intracellular arrangement of these particles are described.
