title: VC11: an actinophage virulent to Streptomyces cattleya and Streptomyces olivaceus.
abstract: Five soil samples were screened for the presence of a virulent actinophage. Phage VC11 was found to be virulent on Streptomyces olivaceus, S. cattleya, S. chartreusis, S. griseus (all important beta-lactam antibiotic producers), S. ambofaciens, S. parvulus, S. alboflavus, S. aureofaciens, and S. lividans TC10. Although restriction-modification systems have been observed in S. olivaceus and S. cattleya, the phage EOP on these hosts remained relatively constant, indicating that these systems do not affect VC11.
