Solobacterium moorei is a sufficiently close phylogenetic relative of Bulleidia extructa for the two species to be in the same genus. No formal proposal has yet been made but the name Bulleidia would take precedence by prior publication.

After 7 days incubation on Fastidious Anaerobe Agar plates (incorporating 5 % horse blood), colonies are 1 mm in diameter, circular, entire, translucent and umbonate. Growth in broth media is markedly stimulated by the addition of 0.5 % Tween 80 in the presence of fermentable sugars.

Gram-posiitive non-sporing anaerobic bacilli [1]. Cells are short and straight or slightly curved and found singly or in pairs. Strains are saccharolytic fermenting fructose, glucose, maltose and sucrose. Acetate and lactate with trace amounts of succinate are formed as the end-products of metabolism. Arginine is hydrolysed and aesculin hydrolysed by some strains. There is no growth in 20 % bile, hydrogen sulfide and indole are not produced and nitrate is not reduced. Urea is not hydrolysed. The mol % G+C content of the DNA is 37-39.

Isolated from the human tongue and dental plaque. It is a member of only a relatively small number of species that are found in both the mouth and faeces

Has been associated with halitosis [2,3] and other infections of dental origin [4,5]. There are case reports of this organism causing septicaemia and vascular infections of various types.
