Morphology Leptotrichia buccalis
CELLULAR  
Staining Gram-negative, often with Gram-positive granules distributed evenly along the long axis.

May be Gram-positive in very young cultures.
Morphology Straight or slightly curved rods, 0.8-1.5 um wide and 5-15 um long, with one or both ends pointed or rounded. Frequently arranged in pairs, chains or septate filaments. No club formation or branching.. have atypical Gram negative tpe wall structure
Motility Nonmotile
Specialized structures no spores
Division  
COLONIAL  
Solid surface Colonies on Blood agar are "medusa head" 1-2 m in diameter at 48 hours

Growth Parameters Leptotrichia buccalis
PHYSIOLOGICAL  
Tropism Chemoorganotrophic. Metabolize carbohydrates with formation of acid without gas.
Oxygen Anaerobic on first isolation; many strains subsequently grow aerobically in the presence of CO2.
pH Good growth occurs at pH 7.0-7.4.
Temperature Optimum temperature, 35-37`C; little or no growth occurs at 25`C.
Requirements Grows best undet an atmsophers contains 5-10% CO2; on repeated transfer some strains may grow aerobically with CO2 For good growth the organsims requires nutrient broth supplemented with yeast extract (0.3%), Glucose (0.5%), cysteine hydrochloride (0.1%) and serum (5%)
Products The major product of glucose fermentation is lactic acid. Acetic and succinic acids may be produced in trace amounts
