Sixty-two isolates of Campylobacter cryaerophila were recovered from aborted porcine and bovine fetuses, from porcine, bovine, and equine feces, and from different tissues of a dead piglet. Phenotypic characterization was carried out on all isolates, and the results were compared with those obtained with the reference strains of C. cryaerophila, C. jejuni, C. coli, C. laridis, and C. hyointestinalis. The ability of C. cryaerophila strains to grow under aerobic conditions at 16 degrees C was found to be most useful in differentiating them from strains of other Campylobacter species. Studies were undertaken to develop a serotyping system for C. cryaerophila on the basis of the Lior serotyping system for C. jejuni and C. coli by use of a tube agglutination test with formalinized whole-cell (FWC) and boiled whole-cell (BWC) antigens. Antisera against 18 strains of C. cryaerophila were produced in rabbits. Thirty-five percent of C. cryaerophila strains were typed with the FWC suspension as an antigen, and 61% were typed with the BWC suspension as an antigen. None of the C. cryaerophila strains tested autoagglutinated in saline. BWC antigens of C. jejuni, C. coli, and C. laridis cross-reacted with C. cryaerophila, whereas FWC antigens did not cross-react. Neither FWC nor BWC antigens of C. hyointestinalis reacted with C. cryaerophila antisera.
