spirillum /spʌɪˈrɪləm /noun (plural spirilla /spʌɪˈrɪlə/)A bacterium with a rigid spiral structure, found in stagnant water and sometimes causing disease.- Genus Spirillum; Gram-negative.
Possibly it is a true spirillum, portions of which appear in the comma shape, much as in other spirilla - e.g., spirilla undula, which do not always form complete spirals, but consist only of more or less curved rods....- These very long, spiraled nascent bdellovibrio were proposed earlier from electron microscope images to be common in spirilla, which are long and coiled themselves.
- The retention of the normal shape that we observed may be caused by steric restrictions on a major change in shape and size by neighboring spirilla and bdellovibrios.
OriginModern Latin, irregular diminutive of Latin spira 'a coil'. |
