Pasteurella Bacteriophage Sex Specific in Escherichia coli.
Phage H, thought to be specific for Pasteurella pestis, was shown to plate efficiently on F(-) strains of Escherichia coli but not on F(+), F', or Hfr strains. The phage was adsorbed rapidly to F(-) strains but was not adsorbed to strains carrying F. Comparison with seven other reported female-specific phages showed that, although phage H was similar to the other phages in some characteristics,...
متن کاملSex and virulence in Escherichia coli: an evolutionary perspective
Pathogenic Escherichia coli cause over 160 million cases of dysentery and one million deaths per year, whereas non-pathogenic E. coli constitute part of the normal intestinal flora of healthy mammals and birds. The evolutionary pathways underlying this dichotomy in bacterial lifestyle were investigated by multilocus sequence typing of a global collection of isolates. Specific pathogen types [en...

متن کاملGenetic variation in the sex factor of Escherichia coli.
The mating type of Escherichia coli is determined by the presence or absence of the sex factor (F). Cells which lack F are genetic recipients or females, and are designated F-; cells which possess F may be genetic donors, or males (Lederberg et al., 1952). Two types of males have been described: F+, in which the sex factor behaves as though it were a population of autonomous, extrachromosomal p...
متن کاملFunctional motifs in Escherichia coli NC101
Escherichia coli (E. coli) bacteria can damage DNA of the gut lining cells and may encourage the development of colon cancer according to recent reports. Genetic switches are specific sequence motifs and many of them are drug targets. It is interesting to know motifs and their location in sequences. At the present study, Gibbs sampler algorithm was used in order to predict and find functional m...
