During a survey in a dairy plant in Italy, the second strain (strain FG 206) of Arcobacter suis described in the literature was isolated from raw water buffalo milk.

Phenotypical characterization and 16S rRNA-RFLP gave a complete overlap of results for the two strains.

The recovery of strain FG 206 from a dairy plant shows that this species of Arcobacter is present in the food chain.

Abstract

During a survey in a dairy plant in Italy, the second strain (strain FG 206) of Arcobacter suis described in the literature was isolated from raw water buffalo milk. The objective of this study was to confirm the species identification, better define the species by comparing its characteristics with those of the reference strain (F41T =CECT 7833T =LMG 26152T) and to investigate its potential clinical relevance by detecting the virulence gene pattern of the new strain. Phenotypical characterization and 16S rRNA-RFLP gave a complete overlap of results for the two strains. As expected, an RFLP pattern common to A. suis and A. defluvii was obtained by MseI endonuclease digestion, and a pattern specific for A. suis was obtained by BfaI endonuclease digestion. 16S rRNA sequencing and multilocus phylogenetic analysis (MLPA) showed a robust relatedness of strain FG 206 to the A. suis type strain F41T. The recovery of strain FG 206 from a dairy plant shows that this species of Arcobacter is present in the food chain. Like the type strain recovered from pig meat, the species Arcobacter suis may not be confined to a single type of food.
