The genera Campylobacter, Arcobacter, Helicobacter, Wolinella, and "Flexispira" constitute, within the class Proteobacteria, a separate eubacterial lineage identified as rRNA superfamily VI. A considerable number of common genotypic and phenotypic features differentiate the genera Campylobacter and Arcobacter from the other members of this group. Therefore, we propose that the genera Campylobacter and Arcobacter should be included in a separate family, for which the name Campylobacteraceae is proposed.The bacteria now known as campylobacters were first isolated at the beginning of this century (20), when they were named Vibrio fetus (37). In the subsequent decades, similar organisms were found and included in the genus Vibrio as Vibrio jejuni (36), Vibrio coli (6), Vibrio sputorum (26) In Bergey 's Manual of Determinative Bacteriology, 8th ed., the genera Spirillum and Campylobacter constitute the family Spirillaceae (33). The grouping of these taxa in one family was based mainly on a number of morphological features. In 1984, when Bergey's Manual of Systematic Bacteriology was published, the phylogenetic relationships of these organisms were still largely unknown. Therefore, it was decided to discontinue the use of the family name Spirillaceae (13). The genus Campylobacter and some other genera, such as Spirillum, Aquaspirillum , Oceanospirillum , and Azospirillum, were considered to belong to a loose assemblage of taxa that have some morphological or physiological similarities which are useful for identification (13). In Bergey's Manual of Systematic Bacteriology, the genus Campylobacter consists of the following five species (35): C. fetus, C . jejuni, C. coli, C. sputorum, and Campylobacter concisus. C. concisus was described in 1981 by Tanner et al. (41). Furthermore, Smibert listed a third subspecies of C. sputorum, C. sputorum subsp. mucosalis (16), which had been described and named by Roop et al. (29,30) as a separate species. These authors also showed that V . fecalis (7) is related to C. sputorum at the species level and proposed that C. sputorum subsp. sputorum, C. sputorum subsp. bubulus, and V. fecalis (7) should be considered biovars of C . sputorum (C. sputorum biovar sputorum, C. sputorum biovar bubulus, and C. sputorum biovar fecalis, respectively fetus, C. hyointestinalis, C. concisus, C. mucosalis, C. sputorum, C. coli, C. jejuni, C. lari, and "C. upsaliensis." C. cinaedi, C. fennelliae, C . pylori, and W . succinogenes constitute a second rRNA homology group, and C. cryaerophila and C. nitrofigilis form a third rRNA homology group. Goodwin et al. (11) transferred one of these species, C. pylori, to the new genus Helicobacter; although no suprageneric studies were performed, a second species, C. mustelae, was also included in the same genus.All known campylobacters, wolinellas, and Campylobacter-like organisms were included in an extensive DNArRNA hybridization study by Vandamme et al. (45). These authors found that all campylobacters and their relatives (including the genera Wolinella a...

“…These oxidase-positive, catalase-negative bacteria were found to constitute a separate DNA relatedness group and were therefore removed as a subspecies of C. sputorum and given status as a separate species (145). The characteristics of C. mucosalis and its close relationship to C. concisus have been investigated in detail by Roop et al (144,145) and Tanner et al (166,167). C. mucosalis requires hydrogen or formate (from which it produces hydrogen) as an electron donor for growth.…”

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.

MatdovsU Norika, Olga SladU, o. Mdz, Z. MatyU and Iva Tomancova: Campylobacter jejuni in Slaughtered Chickens from the Viewpoint of Food Hygiene. Acta vet. Bmo, 61, 1992: 61-67.A total of 440 slaughtered chickens coming from 27 farms were examined for presence of Campylobacter jejuni between 1st Feb. 1990 and 31st Tan. 1991. The relevant specimens were taken from the outer and inner carcass surfaces, ileum contents, liver parenchyma and bile from groups of 10 birds each week. Isolation attempts yielded 366 C. jejuni strains. Of the 38 and 47 (10.3 % and 12.8 %) were isolated from the outer and inner carcass surfaces, respectively, 121 (35 %) from ileum contents, 92 (25 %) from liver parenchyma and 68 (18.6 %) from bile.The proportions of contaminated chicken carcasses showed two peaks, reaching 62.5 % and 62 % in Mayand October, respectively. An almost parallel trend vas recorded for the isolations from ileum contents and liver parenchyma where the highest number of strains (45 % and 30 % respectively) coincided with the May peak, whereas the highest proportions of isolations from bile (30 %) coincided rather with the second peak. The proportions of C. jejuni isolated from the outer and inner carcass surfaces were relatively low, averaging 9.4 % and 11.4 % respectively, and did not show much fluctuation. The proportions of C. jejuni isolated from bile averaged 13.8 %.In 82 (22.4 %) C. jejuni strains solitary colonies were observed also after control aerobic incubation at 42 °c, but attempts at their further passage under these conditions yielded negative results. C. jejuni carriers and shedders as well as the incidence of asymptomatic C. jejuni infection among chickens do not urge either the farmer or the veterinarian to take any measures, but the consumption of C.jejuni-infected chicken meat constitutes a major health hazard for man. Campylobacter jejuni, slaughtered chickens, food hygieneCampylobacter jejuni was first described as Vibrio jejuni a ones et a1. 1931) and is also known under the names of Vibrio hepaticus (Mathey and Rissberger 1964) or Campylobacter fetus subsp. jejuni (Smibert 1974). It is a causative agent of abortion in sheep, diarrhoea in calves and lambs, campylobacter hepatitis in chickens and febrile enteritis in man.A point of particular epidemiological importance is the fact that C. jejuni can also be iso'ated from the intestinal tract of clinically healthy cattle, sheep, goats, pigs, rabbits, domestic fowls, nirkeys, ducks, pigeons, dogs, cats, monkeys, sparrows, blackbirds and starlings (Smibert 1984). From the intestinal tract it can make its way to the liver and, upon evisceration, also to the outer and inner surfaces of farm animal carcasses. In the domestic fowl this possibility has been demonstrated:(1) on the outer sUrface after scalding and plucking (Baker et al. 1987) in 20 % of the carcasses;(2) on the inner surface after evisceration (Pl!gfimkova 1986, Marinescu et al. 1987 Mfl!-kova 1987) in 28.7 % to 92 % of the carcasses; (3) in the liver (Khalafalla 1990) in 40...
