Plants have diverse and vast niches colonized by endophytic microorganisms that promote the well being of host plant. These microbes inhabit internal plant tissues with no signs of ill health. Bacterial endophytes from many plants have been isolated and characterized due to their beneficial roles however their diversity in leguminous plants still remain unexploited. Diversity of bacterial endophytes isolated from L. diversifolia, S. sesban and C. Salothyrsus were assessed using morphological and molecular characteristics. A total of 27 pure isolates were recovered from C. Calothyrsus, L. diversifolia and S. sesban constituting 44.4%, 31.8% and 23.8% from the leaves, stems and roots respectively. The isolates differentiated into Gram positive and negative with rods and spherical shapes. Analysis of 16S rRNA gene sequence revealed 10 closely related bacterial genera that consisted of Bacilli (33.3%), Staphylococcus (22.2%), Alcaligens (11.2%), Xanthomonas and Sphingomonas (47.4 %). Others included Enterobacteria, Pantoea, Acinetobacter, Pseudomonas and Bacterium. These results indicate the presence of high diversity of endophytic bacteria associated with the different parts of L. diversifolia, S. sesban and C. salothyrsus growing in western Kenya.
