BACTERIOPHAGE COMMON TO PASTEURELLA PESTIS AND ESCHERICHIA COLI.

abstract：:Myxococcus xanthus mutants resistant to a clear-plaque derivative of phage Mx8 were isolated. A significant fraction of the mutants, easily recognizable by their colony morphology, were induced by the presence of the phage and may correspond to low-frequency lysogens. They were all defective in cell motility and showe...
