Studies on Streptococcal Bacteriophages
Evidence has been presented that the burst size in the Group A and Group C streptococcal phage-host systems are in general similar producing approximately 13 phage particles per infected coccus. The exception was the C1 phage which produced 10 times more virus particles than all the other phages tested. The eclipse period for the A25 phage-host system was found to extend for 34 min, while the C...
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...
متن کاملBroad host range of streptococcal macrolide resistance plasmids.
Four macrolide-lincosamide-streptogramin B resistance plasmids transferred into 13 recipients belonging to Streptococcus, Staphylococcus, and Listeria genera. The plasmids were stably maintained in all new hosts except Streptococcus sanguis, Streptococcus pneumoniae, Staphylococcus aureus, and Listeria innocua and were identical to those found in the corresponding donor strains.
متن کاملMorphology of the bacteriophages of lactic streptococci.
Electron microscope studies have been made of a number of phages of lactic streptococci, seven of which were phages of Streptococcus lactis C10. Two of the phages are thought to be identical; five have been classified by the method of Tikhonenko as belonging to group IV (phages with noncontractile tails) with type III tail plates; one belongs to group V (phages with tails possessing a contracti...
متن کاملIntergroup lysis and transduction by streptococcal bacteriophages.
Bacteriophages from streptococci of groups A, E, and G lysed streptococci distributed among serogroups A, C, G, H, and L; propagated in some, but not all, of these; and transduced streptomycin resistance within group A or (by A phages only) from group A to group G streptococci.
