[Characteristics of phages of spore-forming bacteria isolated from the soil].

Phages lyzing spore forming bacteria were isolated from soil, and their biological properties and fine structure were studied. The spectrum of lytic activity was determined as well as parameters of the intracellular phage growth. The burst size of the phage varies from 8 to 725 particles per infected cell, the latent period lasts 25-100 min for various phages. According to the data of electron microscopy, the phages are divided into three morphological groups. The phages Tg7, AR13 and BPP10 have a complex structure.
