“…strain FWKO B. Arcobacter spp., like FWKO B, are gram-negative, motile, curved rods. They do not ferment glucose, and they grow at temperatures between 15 and 40°C, reduce nitrate, and grow under microaerophilic conditions (38,39,64,68). However, unlike other Arcobacter spp., FWKO B is catalase and oxidase negative.…”

Bacterial strains CVO and FWKO B were isolated from produced brine at the Coleville oil field in Saskatchewan, Canada. Both strains are obligate chemolithotrophs, with hydrogen, formate, and sulfide serving as the only known energy sources for FWKO B, whereas sulfide and elemental sulfur are the only known electron donors for CVO. Neither strain uses thiosulfate as an energy source. Both strains are microaerophiles (1% O 2 ). In addition, CVO grows by denitrification of nitrate or nitrite whereas FWKO B reduces nitrate only to nitrite. Elemental sulfur is the sole product of sulfide oxidation by FWKO B, while CVO produces either elemental sulfur or sulfate, depending on the initial concentration of sulfide. Both strains are capable of growth under strictly autotrophic conditions, but CVO uses acetate as well as CO 2 as its sole carbon source. Neither strain reduces sulfate; however, FWKO B reduces sulfur and displays chemolithoautotrophic growth in the presence of elemental sulfur, hydrogen, and CO 2 . Both strains grow at temperatures between 5 and 40°C. CVO is capable of growth at NaCl concentrations as high as 7%. The present 16s rRNA analysis suggests that both strains are members of the epsilon subdivision of the division Proteobacteria, with CVO most closely related to Thiomicrospira denitrifcans and FWKO B most closely related to members of the genus Arcobacter. The isolation of these two novel chemolithotrophic sulfur bacteria from oil field brine suggests the presence of a subterranean sulfur cycle driven entirely by hydrogen, carbon dioxide, and nitrate.

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.

The genus Campylobacter: a decade of progress

In 1977, microbiologists and clinicians were awakened to the importance of the genus Campylobacter when it was learned that one species, Campylobacter jejuni, was a major cause of human enteritis. In the following decade substantial advances were made in diagnosis, isolation technology, identification, classification, serotyping, and epidemiology. The genus has undergone rapid expansion as advantage was taken of the deoxyribonucleic acid-deoxyribonucleic acid hybridization technique in defining new species. The 14 species now included in the genus, however, constitute a widely diverse group, and one species, C. pylori, which is associated with human gastroduodenitis, is under consideration for reassignment to another genus. The nomenclature of the subspecies of C. fetus has been resolved and the role of C. fetus subsp. fetus as an agent of human infections has been more clearly defined. The thermophilic campylobacteria that are etiological agents of human enteritis now include three species, C. jejuni, C. coli, and C. laridis. Recently defined species that have also been implicated as enteritis-causing agents include C. hyointestinalis, "C. upsaliensis," "C. cinaedi," and "C. fennelliae." The aerotolerant campylobacteria are now included in the species C. cryaerophila, and the campylobacteria isolated from salt marshes are included in C. nitrofigilis. The taxonomy and nomenclature of C. sputorum have been revised. C. sputorum now consists of three biovars (biotypes). Two of these, biovar sputorum and biovar bubulus, were previously considered to be separate subspecies and the third, biovar fecalis, was previously regarded as a separate species and known as "C. fecalis." The former subspecies C. sputorum subsp. mucosalis has been elevated to the rank of species. C. mucosalis is metabolically closely related to C. consisus. Human pathogens have not been identified among C. sputorum, C. mucosalis, or C. concisus. The goal of this article is to review developments during the last 10 years with emphasis on changes in taxonomy that are important from the perspective of the clinical microbiologist.
