Interpretive Summary:

Technical Abstract: Organisms resembling Campylobacter, now designated as Arcobacter, have been described from aborted farm animals in Europe and Canada and from cases of human enteritis throughout the world. The goals of this study were: (1) to recover Arcobacter spp. from cases of porcine abortion submitted to the state veterinary diagnostic laboratories, and (2) to characterize these isolates by conventional phenotypic tests and ribotyping. Isolates of Arcobacter from North Carolina (n=32) and Iowa (n=33) were recovered from porcine tissues using both direct plating and filtration from P-80 transport medium. In the Iowa portion of the study, Arcobacter were recovered from 43% (13/30) of porcine abortion cases examined. Isolations were made from placenta (42%), kidney (46%), and stomach contents (12%) which were the only tissues examined. The most reliable tests used to phenotype A. butzleri included: growth in 1% glycine and in 1.5% NaCl, weak catalase activity, and resistance to cadmium chloride. Arcobacter cryaerophilus strains were characterized by strong catalase activity, variable ability to grow in 1% glycine, and sensitivity to cadmium chloride. The two subgroups of A. cryaerophilus could not be distinguished using common Campylobacter phenotypic tests.
