Abstract
The diversity of 43 bacterial strains isolated from Beninese entomopathogenic nematodes was investigated molecularly by analyzing the 16S rRNA, recA, and gyrB genes. Based on 16S rRNA sequence analysis, 15 bacterial strains were identified as Xenorhabdus sp., 27 strains as Photorhabdus sp., and one as Serratia sp. The Xenorhabdus strains were isolated from Steinernema nematodes and identified as Xenorhabdus indica based on 16S rRNA gene and concatenated recA and gyrB sequence analysis. However, analysis of 16S rRNA and concatenated recA and gyrB gene sequences of the Photorhabdus strains, all isolated from Heterorhabditis nematodes, resulted in two separate sub-clusters (A) and (B) within the Photorhabdus luminescens group, distinct from the existing subspecies. They share low sequence similarities with nearest phylogenetic neighbors Photorhabdus luminescens subsp. luminescens Hb(T), Photorhabdus luminescens subsp. caribbeanensis HG29(T), and Photorhabdus luminescens subsp. noenieputensis AM7(T).
