| description of porphyromonas circumdentaria sp. nov. and reassignment of bacteroides salivosus (love, johnson, jones, and calverley 1987) as porphyromonas (shah and collins 1988) salivosa comb. nov. | a new species, porphyromonas circumdentaria, is proposed for pigmented, asaccharolytic strains that were isolated from the gingival margins or mouth-associated diseases of cats. this bacterium is an obligately anaerobic, gram-negative, brown- or black-pigmented, asaccharolytic, nonmotile, nonsporing, rod-shaped organism which does not grow in bile and has a guanine-plus-cytosine content of 40 to 42 mol%. it produces major amounts of acetic, butyric, and isovaleric acids and minor amounts of prop ... | 1992 | 1503973 |
| porphyromonas gingivicanis sp. nov. and porphyromonas crevioricanis sp. nov., isolated from beagles. | two new species, porphyromonas gingivicanis and porphyromonas crevioricanis, are proposed for black-pigmented, asaccharolytic, anaerobic, nonmotile, non-spore-forming, gram-negative, rod-shaped organisms. these organisms were isolated from the gingival crevicular fluids of beagles. p. gingivicanis and p. crevioricanis do not grow in the presence of 20% bile. they exhibit less than 5% dna-dna homology with the type strains of porphyromonas gingivalis (strain atcc 33277), porphyromonas endodontali ... | 1994 | 7981094 |
| porphyromonas canoris sp. nov., an asaccharolytic, black-pigmented species from the gingival sulcus of dogs. | a new species, porphyromonas canoris, is proposed for black-pigmented asaccharolytic strains isolated from subgingival plaque samples from dogs with naturally occurring periodontal disease. this bacterium is an obligately anaerobic, nonmotile, non-spore-forming, gram-negative, rod-shaped organism. on laked rabbit blood or sheep blood agar plates, colonies are light brown to greenish brown after 2 to 4 days of incubation and dark brown after 14 days of incubation. colonies on egg yolk agar and on ... | 1994 | 8186085 |
| structural characterization of the o-antigenic polysaccharide chain of porphyromonas circumdentaria nctc 12469. | structural studies were carried out on an o-antigenic polysaccharide moiety derived from porphyromonas circumdentaria nctc 12469, a reference strain of porphyromonas species. the polysaccharide chain was composed of d-glucose, d-galactose, n-acetyl-d-glucosamine, and n-acetyl-d-galactosamine in a molar ratio of 1:2:1:1. on the basis of results from 1h- and 13c-nmr spectroscopic analyses including cosy, tocsy, and hmqc experiments together with results of smith degradation, methylation analysis, ... | 2001 | 11386420 |

| the influence of oral bacteria on tissue levels of toll-like receptor and cytokine mrnas in feline chronic gingivostomatitis and oral health. | feline chronic gingivostomatitis (fcgs) is an inflammatory disease of the oral cavity that causes severe pain and distress in affected cats. treatment methods are currently very limited. the aims of this study were to assess the feline innate immune response by investigating the levels of cytokine and toll-like receptor (tlr) mrnas in tissue biopsies of cats with and without fcgs, and to relate this to the presence or absence of putative oral pathogens identified previously within these cats. mu ... | 2012 | 23287555 |
