Nathan,

There are publications that specifically say Photorhabdus luminescens is linked to these infections; however, this is not the case. Upon genetic squencing, these cases were actually caused by a newly identified species of Photorhabdus, Photorhabdus asymbiotica. P. asymbiotica is also luminescent when cultured in the clinical laboratory. The nematode host carrying this bacteria was recently (< 2 years ago) discovered in Austrailia.
