VIBRIOS FROM CALVES AND THEIR SEROLOGICAL RELATION TO VIBRIO FETUS.

The calf vibrios thus far studied include one strain serologically distinct from the fetal strains. The others are closely related to the fetal strains though not identical with them. The pathogenic characters of the calf vibrios, either as possible descendents of Vibrio fetus, or as independent factors in the production of enteritis have not been demonstrated.
