“Background Arcobacter spp. are emerging enteropathogens and potential zoonotic this website agents that can be transmitted by food and water [1]. Previous studies have demonstrated a relationship between the presence of arcobacters in water samples and bacterial indicators of faecal pollution [2, 3]. This genus Selleckchem RAD001 belongs to the Campylobacteraceae family and was originally proposed by Vandamme et al. in 1991 [4] to accommodate two aerotolerant species (Arcobacter cryaerophilus

and Arcobacter nitrofigilis), which had previously been included in the Campylobacter genus. Since 2009, the number of newly described species has risen exponentially, and the genus currently comprises 18 species, eight of which were described in our laboratory [1, 5–8]. The identification of Arcobacter spp. by phenotypic testing is difficult. This is because they can easily be confused with Campylobacter spp. [1, 9]. This has led to the design of many different molecular detection and identification methods. These are based on conventional PCR, multiplex PCR (m-PCR), ADP ribosylation factor Real Time PCR (RT-PCR), Restriction Fragment Length Polymorphism (RFLP), Denaturing Gradient Gel Electrophoresis PCR (DGGE-PCR), Fluorescence in situ Hybridisation (FISH)

and Matrix Assisted Laser Desorption Ionization Mass Spectrometry (MALDITOF MS); these methods are reviewed by Collado & Figueras [1]. The majority of PCR based methods [10–13] target the genus, or only Arcobacter butzleri and/or A. cryaerophilus[1] and references therein]. Others also include Arcobacter skirrowii[14, 15] or Arcobacter cibarius[16]. In 2010, Douidah et al. proposed a new m-PCR method that could identify the five species associated with humans or other mammals, i.e. A. butzleri, A. cryaerophilus, A. skirrowii, A. cibarius and Arcobacter thereius[9]. This m-PCR method was not able to detect Arcobacter trophiarum, which was originally isolated from pigs by De Smet et al. [17].
