| Morphology | Falcivibrio |
| CELLULAR |
| Staining | Young cultures stain Gram positive but older culutres stain Gram negative with Gram positive granules |
| Morphology | slende, irregular curved rodseith clubbed or tapering ends arranged either singly or in pairs. The pairs show a sickle configuration |
| Motility | motile by polar or subpolar flagella from the concave side of the cell |
| Specialized structures | non sporing |
| Division |
| COLONIAL |
| Solid surface | colonies are small(1 mm diameter) white and on bllod agar they exhibit beta hemolysis or greening of the agar |
| Liquid |
| Growth Parameters | Falcivibrio |
| PHYSIOLOGICAL |
| Tropism | chemoorganotropic |
| Oxygen | anaerobic but the cells may become tolerant to 5% oxygen on culture |
| pH | |
| Temperature | optimum growth temperature is 37 oC |
| Requirements | require nutrionally rich media, growth is stimulated by fumarate which is reduced to succinate |
| Products | metabolism is fermentative, may porduce acid from glucose and other carbohydrates, indole negative,may reduce nitrates |
| Enzymes | catalase negative, oxidase negative, |
