Lysogeny of Streptococcus pneumoniae with MM1 phage: improved adherence and other phenotypic changes.
Pneumococcal prophages are extremely frequent, but no role in pathogenesis has so far been attributed to them. We isolated a variant of phage MM1, named MM1-1998, from a serotype 24 strain of Streptococcus pneumoniae. We created three isogenic strain pairs (serotypes 3, 4, and 24) that differed only by the lysogenic presence of the MM1-1998 phage and did a phenotypic comparison. Lysogeny led to...
متن کاملProbability landscape of heritable and robust epigenetic state of lysogeny in phage lambda.
Computational studies of biological networks can help to identify components and wirings responsible for observed phenotypes. However, studying stochastic networks controlling many biological processes is challenging. Similar to Schrödinger's equation in quantum mechanics, the chemical master equation (CME) provides a basic framework for understanding stochastic networks. However, except for si...
متن کاملTwo Sequential Repressions of Dna Synthesis in the Establishment of Lysogeny by Phage P22 and Its Mutants.
I In a previous publication,8 we reported for the older Type II Sigma ribonuclease a value of An/c = 0.185 ml/gm. We now correct this value to 0.187 ml/gm; however, the precision cannot be evaluated with confidence. 8 Clarke, A. M., D. W. Kupke, and J. W. Beams, J. Phys. Chem., 67, 929 (1963). 9 McMeekin, T.

متن کاملDetection of proteins synthesized during the establishment of lysogeny with phage P22.
A method is described which utilizes pulse labeling with Sa5, starch gel electrophoresis, and autoradiography to detect the synthesis of proteins at various times after infection of Salmonella typhimurium with phage P22. The system was developed especially to study proteins involved in lysogeny. A comparison was made of various infections. These involve the wild-type phage (c+) under conditions...
متن کاملTyping of nontypable staphylococci by lysogeny.
Strains of coagulase-positive staphylococci which were nontypable with the routine typing set of phages could be typed by lysogeny with phage-propagating strains as indicators and with ultraviolet induction. About 10% of the strains could be typed without induction. About 36% of them could be typed by this method when ultraviolet irradiation was used as an inducing agent. The phage groups from ...
