Abstract

Although five Bacteroides fragilis bacteriophages isolated over a six-year period in Nebraska and Virginia had similar physical characteristics (morphology, temperature inactivation, and sensitivity to organic solvents and antisera), there were some statistically significant differences between the phages. In addition, restriction endonuclease analysis revealed that three of the five DNAs were not identical. However, the DNAs of the phages were closely related based on DNA-DNA hybridization, percent homologies, and possession of homologous regions of DNA. It appears that the five phages are strains of the same species of phage, although each phage has a unique host range spectrum.
