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

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,
Unique features  
ENVIRONMENTAL  
Habitat isolated from the human vagina
