Absence of immunity to superinfection in spheroplasts of a lysogen.
نویسندگان
چکیده
Penicillin-induced spheroplasts of Salmonella typhimurium strain LT2 lysogenic for bacteriophage P22, appear to lose immunity to superinfection by homologous phage.

Genetics of bacteriophage P22. I. Isolation of prophage deletions which affect immunity to superinfection.
Two kinds of prophage deletions of the Salm.onella phage P22 were isolated. One type of deletion was isolated by simultaneously selecting for loss of a host gene (pro) adjacent to the integrated prophage and for survival at the nonpermissive temperature of a temperature-inducible (tse2) lysogen. The second type of deletion was isolated by transduction to tetracycline resistance using high-frequ...
متن کاملThe Extractability of Inner-Membrane Proteins from Salmonella typhimurium Intact Cells, Spheroplasts and Inner-Membrane Fragments by Non-Denaturing Detergents
The effect of Triton X-100, Na cholate and Tween 80 on the solubilization of integral membrane proteins in intact cells, spheroplasts and inner-membrane fragments of Salmonella typhimurium was studied. The detergents were used in various concentrations (1.6 to 64 mM) and cytochromes b and d were used as marker to monitor the solubilization of membrane-bound proteins. Results showed that no inne...
متن کاملTransport in bacteriophage P22-infected Salmonella typhimurium.
There was rapid efflux of L-leucine, L-phenylalanine, and alpha-methyl-D-glucoside after infection of Salmonella typhimurium with the clear plaque mutant C1 of phage P22. The efflux was similar to that observed with cyanide or arsenate treatment except that there was partial recovery in the case of phage infection and almost complete recovery under the condition of lysogeny. There was no efflux...
متن کاملSuperinfection exclusion by P22 prophage in lysogens of Salmonella typhimurium. 1. Exclusion of generalized transducing particles.
P22-mediated generalized transduction in S. typhimwiwn occurs in both sensitive and lysogenic recipient bacteria, but the efficiency of transduction is significantly higherinsensitivecells t.han in wild-type P22 lysogens. This reduction in the efficiency of transduction is under the control of the prophage sieA gene; this gene is also responsible for the exclusion of superinfect,ing phage. Expe...
متن کاملCharacterization of the relationship between integrase, excisionase and antirepressor activities associated with a superinfecting Shiga toxin encoding bacteriophage
Shigatoxigenic Escherichia coli emerged as new food borne pathogens in the early 1980s, primarily driven by the dispersal of Shiga toxin-encoding lambdoid bacteriophages. At least some of these Stx phages display superinfection phenotypes, which differ significantly from lambda phage itself, driving through in situ recombination further phage evolution, increasing host range and potentially inc...
