Bulleidia extructa (HMT-603)
Taxon Description:
Solobacterium moorei is a closely related species and on the basis of its position in the 16S rRNA phylogenetic tree appears to represents a novel species within the genus Bulleidia. The name Bulleidia would have precedence by prior publication under Rule 27 of the Bacteriological Code.

Disease Associations:
Isolated from subgingival plaque in periodontitis and from odontogenic infections [234].

Prevalence and Source:
Found in the human mouth

Genotypic Description:
Phenotypic Characteristics: Gram positive short rods [1]. Obligate anaerobes. Ferment glucose and maltose. Metabolic end-products of glucose metabolism are moderate amounts of acetate and lactate and trace amounts of succinate. Arginine is hydrolysed. mol % G+C content of the DNA is 38.
Cultivability: Slow growth on Fastidious Anaerobe Agar + 5 % horse blood. After 7 days incubation colonies are 0.7-0.9 mm in diameter circular entire low convex grey to off-white opaque and glossy
