Anthrax-specific "AP 50-like" phages isolated from Bacillus cereus strains
Acta Microbiologica Academiae Scientiarum Hungaricae
|January 1, 1982
Summary
Researchers isolated specific phages targeting Bacillus anthracis from Bacillus cereus cultures. These phages, similar to AP 50, represent a distinct group affecting Bacillus strains.
Area of Science:
- Microbiology
- Virology
- Bacteriology
Background:
- Bacillus anthracis causes anthrax.
- Bacteriophages are viruses that infect bacteria.
- Specific phages targeting Bacillus anthracis are of research interest.
Purpose of the Study:
- To isolate and characterize phages with specific activity against Bacillus anthracis.
- To compare newly isolated phages with known Bacillus phages.
Main Methods:
- Isolation of phages from mitomycin C-induced Bacillus cereus lysates.
- Electron microscopy for phage morphology.
- Antigenic and chemical structure analysis.
- Host range determination.
- Sensitivity testing (organic solvents, detergents, CsCl).
- Agarose gel electrophoresis for DNA characterization.
Main Results:
- Phages specifically acting on Bacillus anthracis were isolated.
- The isolated phages resembled the previously identified AP 50 phage.
- Phages showed similarities to AP 50 in structure, host range, and sensitivity.
- AP 50 phage nucleic acid was confirmed as DNA via electrophoresis.
- A distinct group of phages targeting Bacillus strains was suggested.
Conclusions:
- A new group of Bacillus-acting phages, including AP 50, has been identified.
- These phages possess unique characteristics differentiating them from other known phages.
- Further research into this phage group could offer insights into phage therapy or bacterial control.
