Basal 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...
متن کاملBasal Bodies of Bacterial Flagella in Proteus Mirabilis
This paper investigates further the question of whether the flagella of Proteus mirabilis emerge from basal bodies. The bacteria were grown to the stage of swarmer differentiation, treated lightly with penicillin, and then shocked osmotically. As a result of this treatment, much of the cytoplasmic content and also part of the plasma membrane were removed from the cells. When such fragmented org...
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 کاملStaining 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 ...
