Staining bacterial flagella easily.
A wet-mount technique for staining bacterial flagella is highly successful when a stable stain and regular slides and cover slips are used. Although not producing a permanent mount, the technique is simple for routine use when the number and arrangement of flagella are critical in identifying species of motile bacteria.
متن کاملBacterial Flagella: Flagellar Motor
Many species of bacteria actively seek out favourable conditions for growth by swimming up gradients of nutrients, oxygen, light or other attractants, or down gradients away from toxic substances (repellants). Different species employ several different modes of swimming, almost all of which are driven by the rapid rotation of helical flagellar filaments that protrude from the cell. Rotation of ...
متن کاملSynthesis of Bacterial Flagella
was developed. This procedure involved measuring the binding of purified, radioactively labeled, antiflagellar antibodies to bacteria. The assay was used to determine the requirements for ribonucleic acid (RNA) and protein synthesis during flagellar regeneration in Bacillus subtilis. Immediate inhibition of flagella development was observed when chloramphenical or puromycin was added to cells. ...
متن کاملDynamic motors for bacterial flagella.
B acterial flagella are dynamic, not only because they rotate and reverse, but also because some of their components exchange on a short time scale. In PNAS, Delalez et al. (1) show that signal-dependent turnover of FliM subunits in the motor–switch complex may be part of the chemotaxis response in Escherichia coli. E. coli swims in a 3D random walk in which “runs” of several seconds are punctu...
متن کاملBasal organelles of bacterial flagella.
Liberated by enzymatic lysis of the cells, the flagella of Rhodospirillum rubrum, R. molischianum, and R. fulvum all have a similar structure. The hook at the base of the flagellum is connected by a short, narrow collar to a paired disc in the basal organelle. This paired disc is in turn connected to a second paired disc. The disposition of flagella to which fragments of the cell membrane still...
