“…Using a qPCR approach, abundance of Arcobacter in Lake Erie beach water was negatively correlated with water temperature in agreement with previous research reporting that they survive better at lower water temperatures (Lee et al, 2012;Salas-Massó et al, 2016). Campylobacter has been observed to have a seasonal occurrence in environmental surface waters in summer/fall that were identified as being from a bovine or wild bird host (Strachan et al, 2013). As Arcobacter has a similar host distribution as Campylobacter it is possible that Arcobacter follows a similar temporal distribution.…”

“…Travel abroad is a prominent risk factor for Campylobacter infection in some northern countries, like Norway, where it occurred in 65% of the cases (8), but less common in others, like Scotland (17%) (9), where it is in the same range as in France.…”

Comparison of Characteristics of Patients Infected by Campylobacter jejuni, Campylobacter coli, and Campylobacter fetus

A large database of Campylobacter isolates precisely identified at the species level was used to compare patients' characteristics. In a multivariate analysis, Campylobacter coli was found more often in older patients and in patients having traveled abroad and less often in summertime than Campylobacter jejuni. Campylobacter fetus infection occurred in much older patients and in hospitalized patients with a systemic disease.T hermotolerant Campylobacter spp. are recognized as the leading cause of bacterial enteric infections worldwide, while Campylobacter fetus often causes systemic infection.A subset of French clinical laboratories participates in the surveillance of Campylobacter infection, carried out by the National Reference Centre (NRC) for Campylobacters and Helicobacters under the leadership of the Institut de Veille Sanitaire (InVS), sending approximately a quarter of campylobacters isolated in France to the NRC.Our aim was to use this large database (Ͼ22,000 strains) to look for differences in the characteristics of the patients and the circumstances under which these Campylobacter species were isolated.(The results of this study were presented as posters at the European Congress of Clinical Microbiology and Infectious Diseases, London, United Kingdom, 2012, and at the Réunion Interdisciplinaire de Chimiothérapie Anti-infectieuse, Paris, France, November 2012.)Network of laboratories. The laboratories sending strains were not randomly selected but were contacted from the list of laboratories already sending isolated Salmonella species to the corresponding NRC. A survey performed in 2009 showed that equal proportions of all strains isolated came from the different regions, with a few exceptions (InVS-NRC, unpublished data). The methods used by these laboratories to isolate Campylobacter species were fairly uniform, including the use of Karmali medium or Campylosel (bioMérieux, Marcy l'Etoile, France) but no filtration techniques.Identification of campylobacters at the NRC. All of the Campylobacter isolates were identified by phenotypic methods at the genus level. From 2003 to 2009, identification to species level was performed both by standard phenotypic methods and a real-time PCR targeting the gyrA gene (accuracy, 99.9%) to differentiate Campylobacter jejuni and Campylobacter coli (1). In the case of negative results, primers specific for C. fetus were used. If no result was obtained, a PCR specific for Arcobacter species was carried out (2). These PCRs allowed the identification of approximately 99% of the isolates. For the remaining 1%, the 16S rRNA gene was sequenced. In 2010, these methods were replaced by matrix-assisted laser desorption ionization-time-of-flight (MALDI-TOF) mass spectrometry identification, which has an accuracy of 99.4% for C. jejuni and 100% for the other Campylobacter species (3).Susceptibility testing was performed by disk diffusion with the same methods and cutoffs from the Comité de l'Antibiogramme de la Société Française de Microbiologie (CA-SFM) that have been used durin...

“…1 In general, reported Campylobacter infections are markedly higher in specific age groups; young children in particular (<5years of age). 3 There are probably varied risk factors with different age groups. [3][4][5] Outside areas other than Europe and North America, incidence reports are relatively rare, and frequently show low detection rates from human samples.…”

“…livestock & wild birds, cause a higher incidence in young rural children in late spring. 3 An extended summer peak linked with chicken strains has been found in adult populations, 3 partially because of barbeques and summer holidays. International trade and travel influence public health globally by affecting patterns of antimicrobial use and resistance selection.…”
