By standard bacteriological techniques the organism was considered to belong to the Chromobacterium lividum group. It was shown to fix nitrogen. By using an antiserum prepared against one strain, four strains were found to be serologically identical and showed some cross-reaction with Agrobacterium tumefaciens. An immunofluorescence technique was used in a search for these organisms in the seed embryo, leaf nodules and other tissues of a number of leaf-nodulated Rubiaceae and Myrsinaceae including Psychotria nairobiensis, Ardisia crispa and a non- nodulated species of Myrsinaceae, Ardisia elliptica. From the results obtained it is concluded that this serotype of Chromobacterium lividum is present in the leaf-nodulated members of these families of plants.", }
