Xenorhabdus magdalenensis

New entomopathogenic nematode Steinernema australe from an island Isla Magdalena by Ganpati Jagdale

New entomopathogenic nematode and its symbiotic bacteria

Based on both the morphological and molecular characteristics, an entomopathogenic Steinernematid nematode isolated from a soil sample collected from Chilean island, Isla Magdalena has been identified as a new species, Steinernema australe (Edgington et al., 2009). This nematode is also symbiotically associated with symbiotic bacteria called Xenorhabdus magdalenensis, which was identified using 16S rRNA gene sequence similarities and a multigene approach (Tailliez et al., 2012).
