title: Morphology and host range of virulent phages of lotus rhizobia.
abstract: Nineteen virulent bacteriophages for fast- and slow-growing rhizobia were isolated. Most of the phage isolates were of two morphological types, and these showed specificity for either the fast- or the slow-growing rhizobia. The ecological distribution, morphology, and host range of the phages is presented. Classification of lotus rhizobia is discussed on the basis of phage typing.
