Occurrence and strain diversity of Arcobacter species isolated from healthy Belgian pigs

In this study, Arcobacter species were isolated from clinically healthy porkers and sows on four unrelated pig farms, using a quantitative isolation protocol. Isolates were identified by m-PCR, and fingerprints were distinguished by modified ERIC-PCR. The prevalence of Arcobacter in pigs ranged from 16 to 85%. Arcobacter excretion ranged from 0 to 10 4 CFU g −1 feces. Arcobacter butzleri was the most frequently occurring species, but simultaneous shedding of two or three species occurred. Large heterogeneity among the Arcobacter species was detected in pigs and on the farms.
