Reversible expression of flagella in Campylobacter jejuni.
Campylobacter jejuni 81116 and A3249 undergo a bidirectional transition between flagellated (Fla+) and aflagellated (Fla-) phenotypes. When measured in culture medium, the Fla+----Fla- transition occurred at a rate of 3.1 X 10(-3) to 5.9 X 10(-3) per cell per generation, and the Fla- to Fla+ transition occurred at a rate of 4.0 X 10(-7) to 8.0 X 10(-7) per cell per generation. However, passage ...
متن کاملTemperature-dependent expression of flagella in Legionella.
Legionella pneumophila, the causative agent of Legionnaires' disease, was analysed by electron microscopy for production of surface structures. Crystalline surface (S-) layers and fimbriae were not detected, but monotrichous flagellation was seen. Polyclonal antibodies specific for the 47 kDa flagellin subunit of L. pneumophila Philadelphia I were used in Western blots to confirm the presence o...

متن کاملSynthesis of bacterial flagella: chromosomal synchrony and flagella synthesis.
Synchronous cultures of Bacillus subtilis 168 M were obtained from light-density spores germinated at 46 C and grown at 37 C. This procedure synchronizes both cell division and chromosome replication. The chromosome synchrony was demonstrated by using transformation to measure changes in marker frequency during the cell cycle. The synthesis of two enzymes and of bacterial flagellar protein was ...
متن کاملDesigning of Testable Reversible QCA Circuits Using a New Reversible MUX 2×1
Recently testing of Quantum-dot Cellular Automata (QCA) Circuits has attracted a lot of attention. In this paper, QCA is investigated for testable implementations of reversible logic. To amplify testability in Reversible QCA circuits, a test method regarding to Built In Self Test technique is developed for detecting all simulated defects. A new Reversible QCA MUX 2×1 desig...
