A Bacteriophage-Typing System for Surveying the Diversity and Distribution of Strains ofErwinia carotovorain Potato Fields

摘要: A bacteriophage-typing system was developed and used to survey the diversity distribution among strains of Erwinia carotovora subsp. E. c. atroseptica from rhizospheres stems potatoes grown in Columbia Basin Pacific Northwest. With a phage enrichment method 25 serogroups as hosts, 13 phages displaying distinct host-range activities were isolated potato soil samples. In addition, strain chrysanthemi isolate N (Ech-3), which did not infect (...)
