“…In the current study, a total of 16 isolates of various Arcobacter spp., including A. cryaerophilus (7), A. skirrowii (7), and A. butzleri (2), that were isolated from 90 samples from the cloacae of domestic geese were examined for their susceptibilities to 20 antibiotics. The results are summarized in the Table. All strains of the 3 Arcobacter spp.…”

“…The genus Arcobacter, previously known as 'aerotolerant campylobacters' , was initially isolated from aborted bovine and pig fetuses (1,2). In 1991, Vandamme et al performed a comprehensive taxonomic study of all known Campylobacter-like organisms and proposed the genus name Arcobacter, which belongs to the epsilon subdivision of the Proteobacteria, called rRNA superfamily VI (3,4).…”

On 6 September 2009 (GMT 21:49) a moderate Mw5.4 earthquake sequence burst at the eastern border of Albania with the Former Yugoslav Republic of Macedonia (FYROM). Th e main shock was located ~6 km north of the epicentre of the 30 November 1967 Mw6.2 Dibra (or Debar) earthquake, which caused loss of life and considerable damage to buildings. We use broad band waveforms recorded by the Hellenic Unifi ed Seismic Network (HUSN), which receives real-time waveforms from the neighbouring networks, to compute focal mechanisms, obtain the slip model and derive the ShakeMap of the mainshock. Th e focal mechanisms of 18 of the stronger events of the sequence, obtained through time-domain moment tensor inversion, indicate that deformation is taken up by NNE−SSW-trending normal faults, in agreement with the ~E−W extension previously identifi ed within the Albanian orogen. Our results show that the 2009 main shock ruptured a roughly 9 km normal fault at a depth of 6 km, which strikes at 194° and dips west at ~45°. Th e slip of the main shock was confi ned to a single patch of ~9 km × 6 km, the average slip was 5 cm and the peak slip was 18 cm. Th e slip model was incorporated in a forward modelling scheme to simulate the ground motion distribution in the near fi eld. Th e ShakeMap thus obtained, based on the distribution of Peak Ground Velocity at phantom stations, outlines the mesoseismal area within the Dibra and Bulqiza districts in Albania, in accordance with macroseismic observations. Th e region aff ected by the 2009 sequence, together with the seismogenic region of the 1967 Dibra event, form a roughly NNE−SSW-trending structure which is an active seismotectonic zone in eastern Albania constituting a threat for nearby urban areas.

“…The genus Arcobacter differs from the genus Campylobacter as it can also grow in normal air at an optimal temperature of 30°C, it does not produce H2S and will grow in the presence of 2-5% NaCl. Arcobacter cryaerophilus has been detected in tissues and faeces from cattle, swine and poultry [15][16][17][18][19] and in man [20]. This bacterium has also been isolated from surface waters in Italy in a survey of the Savena river [21].…”

Arcobacter cryaerophilusand thermophilic campylobacters in a sewage treatment plant in Italy: two secondary treatments compared

SUMMARYMicroaerophilic organisms were monitored in sewage effluent undergoing two secondary treatments: air and oxygen-activated sludge. The mean numbers of Arcobacter cryaerophilus and thermophilic campylobacters detected in incoming sewage were 5639/100 ml and 1720/100 ml respectively.Secondary treatment in air tanks reduced the population of A. cryaerophilus by 971 % and of thermophilic campylobacters by 99-08 %, whereas treatment in oxygen tanks reduced the bacteria 97-8 % and 99-63 % respectively, showing that oxygen-activated sludge treatment was more effective. Subsequent tertiary treatment with 2 p.p.m. chlorine dioxide evidenced the removal ofA. cryaerophilus to 99 9 % and eliminated thermophilic campylobacters.Campylobacter jejuni and C. coli constituted 54-1 % and 45-9 % of 74 thermophilic campylobacter strains isolated. In air-activated sludge effluent C. jejuni was found more often, thus appearing more sensitive to oxygen.The most probable number assay used for detection of campylobacters, blood medium for enrichment and blood-free medium for plating, also appeared to be fit for A. cryaerophilus, the high density of which in urban sewage may be due to inflows from slaughterhouses.

“…Slender, curved, aerotolerant Campylobacter-like bacteria were first isolated from the organs of aborted bovine and porcine fetuses (Ellis et al, 1977(Ellis et al, , 1978. The genus Arcobacter was described in 1991 as a second genus within the family Campylobacteraceae to encompass these bacteria that differ from campylobacters by their ability to grow at temperatures below 30 u C and their aerotolerance (Vandamme et al, 1991).…”

During a Danish study on the prevalence of campylobacteria in pig abortions and food of animal origin, eight Gram-negative, slightly curved, rod-shaped, non-spore-forming bacteria were clustered by using amplified fragment length polymorphism analysis in a distinct phenon within the genus Arcobacter. In the present study, numerical analysis of whole-cell protein profiles also showed that all isolates clustered in a single group distinct from other recognized Arcobacter species. DNA-DNA hybridization among two representative strains exhibited a mean DNA-DNA relatedness value of 79 %. DNA-DNA hybridization with the type strains of recognized Arcobacter species revealed levels of DNA-DNA relatedness of 41 % or less. The DNA G+C content of the type strain was 28.5 mol%. Pairwise comparison of the 16S rRNA gene sequences with those of the type strains of established species identified Arcobacter cryaerophilus (97.9 %), Arcobacter cibarius (97.5 %) and Arcobacter skirrowii (97.2 %) as the nearest phylogenetic neighbours. The isolates could be distinguished from other Arcobacter species by means of the following biochemical tests: activities of catalase and urease, reduction of nitrate and growth on minimal medium, lack of growth at 37 6C under standardized aerobic and microaerobic conditions, in 4 % NaCl and 1 % glycine media. Finally, DNA fingerprints obtained by using enterobacterial repetitive intergenic consenus-PCR showed that the eight isolates represent eight strains of a single novel Arcobacter species, for which the name Arcobacter thereius sp. nov. is proposed. The type strain is LMG 24486 T (5CCUG 56902 T ).
