Abstract

SUMMARY: The best natural habitat for bacteriophages is probably a semi-solid medium containing actively dividing host bacteria. Such conditions are provided for Bacillus and Acetobacter species in rotting grass and apples, respectively. The Bacillus phages found included one with a large head and a contractile tail, and also a so-called killer particle, which had a 350 Å head and a long contractile tail. This particle had the property of killing but not multiplying within a sensitive cell. A new morphological type of virulent Bacillus phage was also isolated; its head was oblong and the tail consisted of a short needle and a plate. The one Acetobacter phage found resembled coliphage T3 but was of particular interest because of the prominence of the head capsomeres and the three-pronged tail.
