Designation of aerotolerant Campylobacter-like organisms from porcine and bovine abortions to the genus Campylobacter.

Unusual helically-curved bacteria isolated from porcine and bovine abortions measured 1.8 microns long and 0.4 microns wide, failed to produce poly beta-hydroxybutyric acid granules and had DNA base compositions within the span 29--34 moles per cent. From this evidence, it was concluded that these organisms are members of the genus Campylobacter.
