| CELLULAR |
| Staining | Gram-negative |
| Morphology | Cells are round to ovoid, 5-25 um in diameter |
| Motility | strongly motile by peritrichous flagella; forward movement is accompanied by rotation around the long axis |
| Specialized structures | . Cytoplasm is often concentrated at one end of the cell, with the remaining space being occupied by a large vacuole. Cytoplasm normally contains orthorhombic sulfur inclusions, sometimes concentrated at one end and sometimes filling cells almost completely. Cells are characterized by the presence of one polar fibrillar organelle, visible in thin sections by electron microscopy; its function is not known. No resting stages are know. Multiplication by constriction followed by fission. |
