Abstract

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 endodontalis (strain ATCC 35406), and Porphyromonas asaccharolytica (strain ATCC 25260), which were isolated from humans, or with the type strains of Porphyromonas salivosa (strain NCTC 11632) and Porphyromonascircumdentaria (strain NCTC 12469), which were isolated from cats. The major cellular fatty acid of P. gingivicanis and P. crevioricanis is13-methyltetradecanoic acid (iso-C-15:0 acid). Glutamate and malate dehydrogenases are present in both species, and 6-phosphogluconate and glucose-6-phosphate dehydrogenases are absent; neither organism exhibits trypsin activity. P. gingivicanis and P. crevioricanis produce large amounts of acetic and isovaleric acids and minor amounts of isobutyric and succinic acids as end products of metabolism in GAM medium. P. gingivicanis also produces large amounts of butyric acid and smalt amounts of propionic acid, while P. crevioricanis produces large amounts of propionic acid and minor amounts of butyric and phenylacetic acids. The G+C contents of the DNA of P. gingivicanis is 41 to 42 mol%; the G+C content of the DNA of P. crevioricanis is 44 to 45 mol%. Catalase is produced by P. gingivicanis but not by P. crevioricanis; strains ofP. crevioricanis agglutinate sheep erythrocytes, but strains of P. gingivicanis do not. The type strain of P. gingivicanis is NUM 301 (= ATCC 55562), and the type strain of P. crevioricanis is NUM 402 (= ATCC 55563).
