MOLECULAR IDENTIFICATION AND GROWTH OF XENORHABDUS AND PHOTORHABDUS SYMBIONTS OF ENTOMOPATHOGENIC NEMATODES

From the characterisation, partial 16 S gene sequences obtained for two bacteria were subjected to blast-bootstrap analysis obtain phylogenetic tree. In assessing similarity of Xenorhabdus bovienii with five other spp., it was found be 96% similar X. nematophila and japonica Accession Numbers D78006 NR027194 respectively. The closer beddingii 95% kazodoii 97% poinarii. tree, species belong genera Xenorhabadus Photorhabdus. compared NR027194, nematophila, poinarii DQ211703, AY278675 kozodoii Eu 190977. results showed that at 20 ? both Photorhabdus luminescens increased a log concentration 7.5 after 6 h. They then slightly up 15 At 25 had 6.1 1 h but only slowly 6.6 However, P. started 5.6 smoothly 30 6.2
