Morphology Anaeroplasma
CELLULAR  
Staining Gram-negative
Morphology Cells of young (16- to 18-h-old) cultures are coccoid, 0.5-2.0 um in diameter. Older cells have a variety of pleomorphic forms.
Motility Nonmotile
Specialized structures Cells are bounded by a plasma membrane only
Division  
COLONIAL  
Solid surface Surface colonies have a dense center with a translucent periphery, or "fried egg" appearance. Subsurface colonies are golden, irregular and often multilobed.
Liquid  

 

Growth Parameters Anaeroplasma
PHYSIOLOGICAL  
Tropism  
Oxygen Obligately anaerobic; the inhibitory effect of oxygen on growth is not alleviated during repeated subcultures
pH Optimum pH, 6.5-7.0.
Temperature Optimum temperature, 37`C; no growth at 26 and 47`C.
Requirements Require sterols for growth
Products Strains vary in their ability to ferment various carbohydrates. The products of carbohydrate fermentation include acids (generally acetic, formic, propionic, lactic and succinic), ethanol, and gases primarily CO2, but some strains also produce H2
Enzymes  
Unique features Bacteriolytic and nonbacteriolytic strains of anaerobic mcoplasmas are described.
ENVIRONMENTAL  
Habitat bovine and ovine rumen.
Lifestyle  
Pathogenicity
