“…The physiological end products of the three asaccharolytic BPBs are shown in Table 1. While the three species produce 140 MAYRAND AND HOLT acetic, propionic, butyric, isobutyric, and isovaleric acids, only one species, B. gin giv'alis, produces phenylacetic acid (63,101,209). In addition, Bourgeau and Mayrand (9) found that the production of this acid was directly proportional to the Trypticase content of the medium and that L-phenylalanine, as well as peptides containing L-phenylalanine, also stimulated phenylacetic acid production.…”

t(alis, and Bacteroiles gingih'alis. (Note: Whenever possible, and appropriate, we will use the most accepted taxonomic designation for the members of the genus Bacteroides. When first discussed, we will use the original designation by the authors followed by our interpretation of that species, using presently accepted taxonomic criteria.) In this review we have attempted to provide a useful synthesis of the literature relevant to the taxonomy, ultrastructure, physiology, serology, ecology, and pathogenicity of the asaccharolytic BPBs and to provide a perspective for their possible role in pathogenesis. OVERVIEW OF THE TAXONOMY In 1921, Oliver and Wherry (130) isolated a small anaerobic gram-negative rod from a variety of sites, including the oral cavity, urine, human feces, and respiratory tract, as well as from postsurgical infections. This rod, when grown on blood agar plates, produced colonies which were black in pigmentation. The pigment was considered to be melanin, and they named the culture Bacteriumn inelaninogenicumn. This bacterium was first described in the third edition of Bergev 's Manula(il of Determinative Bacteriology (7) as Hue-mo10p/uilus 1el(anlilogenicius because better growth was obtained on solid medium containing X and V growth factors characteristic of the members of the genus Haie,niophiluis.

“…The species name Bacteroides gingivalis was proposed by Coykendall et al (2) to accommodate certain brown-toblack-pigmenting organisms, formerly identified as B. asaccharolyticus, found in association with periodontal disease that were probably B. gingivalis (5,7). Members of the species B. gingivalis have been implicated in various forms of periodontal disease and may be associated with other diseases in humans (9,17,23). Although B. asaccharolyticus and B. gingivalis are distinctly different in their DNA guanine-plus-cytosine content (moles percent, G+C) and DNA-DNA homology, their phenotypic characteristics are highly similar (9).…”

Considerable effort has been exerted by various investigators to develop practical, reliable techniques that aid in differentiating or identifying B. gingivalis and B. asaccharolyticus and other phenotypically similar Bacteroides species.…”

Bacteroides gingivalis has been implicated in various forms of periodontal disease and may be responsible for other diseases in humans. The role of B. gingivalis in disease has been difficult to assess, because it is inhibited by most selective media commonly used by clinical laboratories to aid in isolating gram-negative, nonsporeforming anaerobes. We have developed a new mnedium, Bacteroides gingivalis agar, which contains * Corresponding author.

“…in the etiology and pathogenesis of human periodontal diseases and other oral and nonoral infections is being increasingly appreciated (15,17,22,23,26). Bergey's Manual of Systematic Bacteriology (6) recognizes nine black-pigmented Bacteroides species, distinguishable on the basis of phenotypic characteristics and DNA relatedness (1,3,5,7,8). A 10th species of black-pigmented Bacteroides, Bacteroides endodontalis, has recently been proposed (24).…”

Strains of 10 black-pigmented Bacteroides species were serologically characterized using absorbed and unabsorbed rabbit antisera. An agglutination test using intact cells or heated cells (100°C for 60 min) from each species and unabsorbed antisera revealed only homologous reactions with little or no reactivity in heterologous assays. Immunodiffusion tests using sonicated antigen demonstrated that Bacteroides gingivalis, B. endodontalis, B. asaccharolyticus, B. macacae, and B. levii are antigenically distinct. Strains of B. gingivalis, B. endodontalis, and B. asaccharolyticus were also clearly identified by the indirect immunofluorescent antibody method. B. intermedius, B. corporis, B. loescheii, B. melaninogenicus, and B. denticola possessed common antigens; however, species-specific antigens detectable with immunoabsorbed antisera were also demonstrated. B. intermedius strains isolated from the human oral cavity included at least two serogroups. In each black-pigmented Bacteroides species, lipopolysaccharide constituted one of the species-specific antigens.
