“…The base compositions of the DNAs from C. sputorum subsp. mucosalis strains 79-12009 and NCTC llOOOT were 38 and 39 mol% G + C , respectively; these values are higher than the value of 34 mol% G+C reported for strain NCTC llOOOT by Lawson et al (7). The difference may be attributable in part to the use of different equations for calculating the base compositions of the DNAs.…”

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.

“…Topical interest in enteric Campylobacter strains has highlighted the taxonomic diversity of the intestinal strains (52,53), and subsequent characterization studies have identified several new and potentially new species for inclusion within the expanding genus Campylobacter (2,11,16,33,39,60,61).…”

A total of 90 aerotolerant Campylobacter strains, which were isolated mainly from animal abortions, were examined by using a wide range of biochemical and physiological tests. The resulting data, together with data for reference Campylobacter strains that were similarly examined, were compared by using several numerical taxonomic analysis methods. Our analyses demonstrated that there is a strong similarity between the aerotolerant strains and strains of Campylobacter fetus, Campylobacter jejuni, Campylobacter coli, and Campylobacter sputorum. For practical purposes this study revealed four possible taxa; one taxon consisted of C. fetus strains, one taxon consisted of the C. sputorum strains, and a third taxan consisted of the thermophilic strains, having C. coli and C . jejuni strains as separate entities. The fourth. group consisted of all of the aerotolerant strains and was considered a new species of Campylobacter. All of the aerotolerant strains exhibited a tolerance to lower temperatures and higher oxygen concentrations than previously observed with strains of Campylobacter; the name Campylobacter cryaerophila sp. nov. is suggested for these strains. In this paper we present identification characteristics of C. cryaerophila strains and a description of the new species.Since the original observation of "Vibrio fetus" in specimens from ovine abortions (40), a variety ofmicroaerophilic vibrios having the same general description have been reported (2,12,14,16,26,28,34,48,57,60). These organisms have been included in the existing genus Campylobacter (54). Of the catalase-positive strains, Campylobacter fetus strains are usually associated with problems of infertility and abortion in domestic animals. However, we have described the recovery of other spiral, Campylobacter-like organisms from abortions in several animal species (8,9,45). These isolates were recovered by using methods and media that are not usually used for Campylobacter isolation. The isolates were tolerant to atmospheric oxygen on subculture and, although assigned to the genus Campylohacter, did not appear to belong to any of the established groups that have been described previously (44).In the present study, 90 strains recovered from different sources were examined by using physiological and biochemical tests. A numerical taxonomic comparison of these strains and reference Campylohacter strains was made to establish their relationship within the genus Campylohacter and to formulate a scheme for their differentiation. MATERIALS AND METHODSStrains. In this study we used 133 strains, including type and reference strains of some related species (Table 1); 17 of these strains were examined in duplicate to allow us to estimate test error. Most strains had been held for various periods at -70°C or in liquid nitrogen before use, but recently isolated strains were also included. The other reference strains included a " Vihrio percolans" strain, which was representative of aerobic Campylohacter-like organisms isolated from semen (51). The aerotolerant Ca...

Cam.py' lo.bac.ter . Gr. adj. campylo curved; Gr. n. bacter rod; M.L. masc. n. Campylobacter a curved rod. Proteobacteria / Epsilonproteobacteria / Campylobacterales / Campylobacteraceae / Campylobacter Cells of most species are slender, spirally curved rods , 0.2–0.8 × 0.5–5 µm; cells of some species are predominantly curved or straight rods. The rods may have one or more spirals and can be as long as 8 µm. They also appear S‐shaped and gull‐winged when two cells form short chains. Nonsporeforming. Cells in old cultures may form spherical or coccoid bodies. Cells have a multilaminar polar membrane at both ends of the cell that is located under the cytoplasmic membrane. Gram negative. Cells of most species are motile with a characteristic corkscrewlike motion by means of a single polar unsheathed flagellum at one or both ends of the cell. The flagella may be 2–3 times the length of the cells. Cells of other species are nonmotile ( Campylobacter gracilis ) or have multiple flagella ( Campylobacter showae ). Occasionally differences in the number of flagella shown by cells in a single culture are seen ( Campylobacter hyointestinalis ). The mol % G + C of the DNA is : 29–47. Type species : Campylobacter fetus (Smith and Taylor 1919) Sebald and Véron 1963, 907 ( Vibrio fetus Smith and Taylor 1919, 301.)
