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).
