Prevalence of Arcobacter Species in Drinking Water, Spring Water, and Raw Milk as Determined by Multiplex PCR

The aim of this study was to investigate the incidence of Arcobacter species in water sources and raw milk from healthy animals in Kayseri, Turkey. A total of 175 samples of drinking water (n = 100), spring water (n = 25), and raw milk (n = 50) were examined. Arcobacter species were isolated using the membrane filtration technique. Overall, 7 (4%) of the 175 samples yielded Arcobacter spp.: 3 (3%) drinking water samples, 1 (4%) spring water sample, and 3 (6%) raw milk samples. Two species of Arcobacter were recovered from the seven positive samples: Arcobacter butzleri, Arcobacter skirrowii, and A. brazier( plus A. skirrowii found in 3 (1.7%), 2 (1.1%), and 2 (1.1%) samples, respectively. Our study is the first to report the isolation of both A. brazieri and A. skirrowii together from drinking water and is the first report of Arcobacter in milk from healthy cows in Turkey. Based on these findings, the presence of Arcobacter species in environmental waters and raw milk may pose a potential hazard for human health.
