Some bacteriophages active against Rhizobium trifolii strain W19.
Fourteen soil bacteriophages active against Rhizobium trifolii W19 have been studied which fall into four structural groups. Group 1 phages have contractile tails. Some particles show double base plates to which at least three spikes are attached, and fibers are attached to the base plates. Group 2 phages also have contractile tails. At least five spikes are attached to the base plate, and ther...
متن کاملEnvironmental Factors Influencing Numbers of Rhizobium leguminosarum biovar trifolii and Its Bacteriophages in Two Field Soils.
Fluctuations in numbers of Rhizobium leguminosarum biovar trifolii and its bacteriophages in two fields with different soil types were followed during a 17-month period in 1981 and 1982. Mean levels of both phage and rhizobia varied significantly (P < 0.05) on different occasions, with rhizobial levels varying from 1.6 x 10 to 2.0 x 10 cell per g of soil and phage from 0 to 1.7 x 10 PFU/g of so...
متن کاملNarrow-host-range bacteriophages that infect Rhizobium etli associate with distinct genomic types.
In this work, we isolated and characterized 14 bacteriophages that infect Rhizobium etli. They were obtained from rhizosphere soil of bean plants from agricultural lands in Mexico using an enrichment method. The host range of these phages was narrow but variable within a collection of 48 R. etli strains. We obtained the complete genome sequence of nine phages. Four phages were resistant to seve...
متن کاملBacteriophage typing of Salmonella. I. Isolation and host range study of bacteriophages.
A series of bacteriophages, lytic for bacteria belonging to the genera Escherichia and Salmonella, were isolated. The phages were isolated from fecal samples, intestinal contents of turkey poults, and carrier cultures of S. typhimurium, S. typhimurium var copenhagen, S. heidelberg, and E. coli. The feasibility of using different habitats as sources of Salmonella phages was evaluated. The carrie...
متن کاملMore Is Better: Selecting for Broad Host Range Bacteriophages
Bacteriophages are viruses that infect bacteria. In this perspective, we discuss several aspects of a characteristic feature of bacteriophages, their host range. Each phage has its own particular host range, the range of bacteria that it can infect. While some phages can only infect one or a few bacterial strains, other phages can infect many species or even bacteria from different genera. Diff...
