Abstract:
Antisera were prepared to Victorian and Rhodesian strains of Pseudomonas solanacearum, and to a culture of the ring rot organism, Corynebacterium sepedonicum, from Canada. It was found that the two strains of Ps. Solanacearum were similar, though distinct serologically, and each quite different from C. sepedonicum, although there was some serological affinity between the three organisms. The common agglutinins were absorbed to produce specific absorbed serum for each organism, the potential value of which is briefly discussed.
