Characterization of Streptococcus durans bacteriophages

Abstract
Streptococcus durans bacteriophages were isolated from bovine rumen fluid, feed lot soil, bovine fecal samples, and lysogenic strains of S. durans. The presence of different phage strains was suggested by antiserum neutralization tests and one-step growth characteristics, whereby the bacteriophages were placed into three distinct, but serologically related, groups. These phages were further characterized by plaque morphology, phage morphology, adsorption kinetics, and pH and temperature effects.
