Morphology | Meniscus glaucopis |
CELLULAR |
Staining | Gram-negative |
Morphology | Curved or straight rods, 0.7-1.0 um in diameter and 2.0-3.0 um in length. Cultures may show single cells, pairs, tightly coiled spirals, S shapes (two cells, one inverted), and doughnut-shaped cells, where the ends are overlapping before division by binary fission has occurred. "Rings" have outer diameters of about 3.0 um.. |
Motility | Non-motile |
Specialized structures | Resting stages not known .Encapsulated. Gas vacuoles arranged at random within cells. |
