“…Of the 23 positive-testing dog samples, 16 (70%) harbored C. upsaliensis, 12 (52%) harbored C. jejuni, and 3 (13%) harbored C. lari. This distribution is consistent with other reports on dogs (3,9,12,16).…”

“…The role of Campylobacter as an enteric pathogen in dogs is much less evident. It is frequently isolated both from animals with symptoms of enteritis and from healthy animals (3,9,12,16). The poor identification of Campylobacter species as animal pathogens may result from the simultaneous presence of multiple strains or species with various pathogenicity characteristics.…”

“…Our findings indicate that CNW strain CG-1, which represents a distinct species as determined by DNA homology data (36), also belongs to this subgroup. A comparison of the phenotypic properties of the four species indicates that they can all grow at 42°C (2, 10, 35,36,39) and that they are all catalase positive except the CNW strains, which may give a negative, weakly positive, or delayed reaction depending on the cultural conditions (37).…”

The phylogenetic relationships of all species in the genus Cantpylobacter, Wolinella succinogenes, and other gram-negative bacteria were determined by comparison of partial 16s ribosomal ribonucleic acid sequences. The results of this study indicate that species now recognized in the genus Campylobacter make up three separate ribosomal ribonucleic acid sequence homology groups. Homology group I contains the following true Campylobacter species: Campylobacter fetus (type species), Campylobacter coli, Campylobacter jejuni, Campylobacter laridis, Campylobacter hyointestinalis, Campylobacter concisus, Campylobacter mucosalis, Campylobacter sputorum, and ' 'Campylobacter upsaliensis" (CNW strains). "Campylobacter cinaedi," 'Campylobacter fennelliue," Campylobacter pylori, and W. succinogenes constitute homology group 11. Homology group I11 contains Campylobacter ctyaerophiza and Campylobacter nitrofigilis. We consider the three homology groups to represent separate genera. However, at present, easily determinable phenotypic characteristics needed to clearly differentiate them are not apparent. The three homology groups are only distantly related to representatives of the alpha, beta, and gamma branches of the purple bacteria, indicating that these bacteria do not belong to any previously defined branch of this phylum.

“…These cultures were incubated aerobically at 37°C for 24 to 48 h. The growth from eight Roux bottles was usually sufficient to yield enough DNA for the experiments. Strain CG-1, which was obtained from C. Gebhart and is an unclassified, catalase-negative or weakly catalasepositive strain similar to the strains described by Sandstedt et al (19), was grown under similar conditions; however, ferrous-bisulfite-pyruvate medium (4) was used in the Roux bottles instead of BF medium supplemented with 0.2% sodium formate. C .…”

Seven strains of Campylobacter sputorum subsp. mucosalis, reference strains of Campylobacter fetus, Campylobacter jejuni, Campylobacter coli, Campylobacter laridis, "Campylobacter hyointestinulis, " ' 'Campylobacter fecalis, " C. sputorum subsp. sputorum, C . sputorum subsp. bubulus, and Campylobacter nitrofigilis, aerotolerant Campylobacter sp. strain 02790, and catalase-negative or weakly catalase-positive strain CG-1 were compared with C. sputorum subsp. mucosalis type strain NCTC 11000 in deoxyribonucleic acid hybridization experiments. Strain NCTC llOOOT (T = type strain) showed a high level of deoxyribonucleic acid homology with all of the C. sputorum subsp. mucosalis strains tested, but no significant homology with any of the other reference strains used, including C. sputorum subsp. sputorum and C. sputorum subsp. bubulus strains. Based on these observations, we propose that C. sputorum subsp. mucosalis be reclassified as Campylobacter mucosalis comb. nov.
