Comparative Detection and Quantification of Arcobacter butzleri in Stools from Diarrheic and Nondiarrheic People in Southwestern Alberta, Canada. J Clin Microbiol 2016; 54:1082-8. [PMID: 26865686 DOI: 10.1128/jcm.03202-15] [Citation(s) in RCA: 27] [Impact Index Per Article: 3.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/04/2015] [Accepted: 02/01/2016] [Indexed: 01/18/2023] Open
Abstract
Arcobacter butzleri has been linked to enteric disease in humans, but its pathogenicity and epidemiology remain poorly understood. The lack of suitable detection methods is a major limitation. Using comparative genome analysis, we developed PCR primers for direct detection and quantification ofA. butzleri DNA in microbiologically complex matrices. These primers, along with existing molecular and culture-based methods, were used to detectA. butzleri and enteric pathogens in stools of diarrheic and nondiarrheic people (n= 1,596) living in southwestern Alberta, Canada, from May to November 2008. In addition, quantitative PCR was used to compare A. butzleridensities in diarrheic and nondiarrheic stools.Arcobacter butzleriwas detected more often by PCR (59.6%) than by isolation methods (0.8%). Comparison by PCR-based detection found no difference in the prevalence ofA. butzleri between diarrheic (56.7%) and nondiarrheic (45.5%) individuals. Rates of detection in diarrheic stools peaked in June (71.1%) and October (68.7%), but there was no statistically significant correlation between the presence ofA. butzleri and patient age, sex, or place of habitation. Densities ofA. butzleriDNA in diarrheic stools (1.6 ± 0.59 log10 copies mg(-1)) were higher (P= 0.007) than in nondiarrheic stools (1.3 ± 0.63 log10copies mg(-1)). Of the 892 diarrheic samples that were positive for A. butzleri, 74.1% were not positive for other bacterial and/or viral pathogens. The current study supports previous work suggesting that A. butzleri pathogenicity is strain specific and/or dependent on other factors, such as the level of host resistance.

A severe case of persistent diarrhoea associated with Arcobacter cryaerophilus but attributed to Campylobacter sp. and a review of the clinical incidence of Arcobacter spp. New Microbes New Infect 2014; 2:31-7. [PMID: 25356338 PMCID: PMC4184587 DOI: 10.1002/2052-2975.35] [Citation(s) in RCA: 70] [Impact Index Per Article: 7.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/03/2013] [Revised: 12/16/2013] [Accepted: 12/19/2013] [Indexed: 01/19/2023] Open
Abstract
Although rarely, Arcobacter spp. have been associated with diarrhoea and bacteraemia. We report a persistent case in a healthy 26-year-old Spanish male of bloody diarrhoea, which was attributed to Campylobacter but in fact was caused by Arcobacter cryaerophilus, as determined by sequencing of the rpoB gene. The isolate was re-identified by matrix-assisted laser desorption ionization time of flight (MALDI-TOF) and genotyped for five putative virulence genes and for seven genes included in the Arcobacter multilocus sequence typing database. The low score obtained by MALDI-TOF indicates the need to complement the database with more isolates. Only the ciaB gene, which encodes for an invasin, was detected. Despite the isolate belonging to a new sequence type, three of the alleles (glnA, pgm and tkt) had been found previously in isolates from faeces of patients with diarrhoea. This study, together with the reviewed literature, indicates that Arcobacter can produce bacteraemia and that the isolation from patients with diarrhoea range from 0.11% to 1.25%. This study also demonstrates that Arcobacter species are confused with Campylobacter spp., as previously suggested. This is one of the factors that leads to underestimation of their incidence together with the use of inappropriate detection and identification methods.

Emerging pathogen Arcobacter spp. in acute gastroenteritis: molecular identification, antibiotic susceptibilities and genotyping of the isolated arcobacters. J Med Microbiol 2012; 61:1439-1444.

Abstract
The aims of this study were as follows: (i) to isolate Arcobacter spp. from the stool samples of patients with gastroenteritis; (ii) to identify them with molecular methods; (iii) to genotype them using enterobacterial repetitive intergenic consensus (ERIC)-PCR; and (iv) to determine their antibiotic susceptibilities. For the study, a total of 3287 diarrhoeal stool samples submitted to the Microbiology Laboratory of the Kayseri Training and Research Hospital, Kayseri, Turkey, between 2010 and 2011 were analysed. Campylobacter blood-free selective medium supplemented with cefoperazone, amphotericin B and teicoplanin was used for isolation. Medium inoculated with stool samples was incubated microaerobically at 37 °C for 72-96 h. Phenotypic tests, a genus-specific PCR and a multiplex PCR were used to identify the arcobacters, whilst ERIC-PCR was used for genotyping and the antibiotic susceptibilities of the isolates were detected by E-test. Arcobacter spp. were isolated from nine of the 3287 samples. These nine isolates were identified as Arcobacter butzleri and all showed different ERIC-PCR profiles. All nine isolates were resistant to ampicillin and susceptible to gentamicin, tetracycline, erythromycin and ciprofloxacin. As far as is known, this is the first study in which A. butzleri has been isolated from human acute gastrointestinal infections in Turkey. According to these results, it is recommended that, when investigating the aetiology of infections of the digestive system in humans, Arcobacter spp. be considered for inclusion. The results of this study should contribute to our knowledge related to A. butzleri infections in humans.

Abstract
The genus Arcobacter, defined almost 20 years ago from members of the genus Campylobacter, has become increasingly important because its members are being considered emergent enteropathogens and/or potential zoonotic agents. Over recent years information that is relevant for microbiologists, especially those working in the medical and veterinary fields and in the food safety sector, has accumulated. Recently, the genus has been enlarged with several new species. The complete genomes of Arcobacter butzleri and Arcobacter nitrofigilis are available, with the former revealing diverse pathways characteristic of free-living microbes and virulence genes homologous to those of Campylobacter. The first multilocus sequence typing analysis showed a great diversity of sequence types, with no association with specific hosts or geographical regions. Advances in detection and identification techniques, mostly based on molecular methods, have been made. These microbes have been associated with water outbreaks and with indicators of fecal pollution, with food products and water as the suspected routes of transmission. This review updates this knowledge and provides the most recent data on the taxonomy, species diversity, methods of detection, and identification of these microbes as well as on their virulence potential and implication in human and animal diseases.
