| Abstract: | We studied the relationship between ten authentic Campylobacter fetus and two C. bubulus strains, and seventeen named vibrios of animal and human origin. All organisms fall within the genus Campylobacter, as defined. Their DNA base composition ranges from 29.8 to 35.9% (G+C). On the basis of similarity of differential biochemical tests and % (G+C), they can be divided into four closely similar groups. - C. fetus var. intestinalis and var. venerialis with 34.7 to 35.9% (G+C).
- Vibrio fecalis with 32.0 to 32.8% (G+C).
- C. bubulus with 30.1 and 30.6% (G+C).
- The cluster V. jejuni, V. coli, Vibrio sp. from fowl, and related vibrios from man and sheep with 29.8 to 34.0% (G+C).
We propose that all the vibrios used here be included in the genus Campylobacter. |
