Using a DNA microarray to investigate the distribution of insect virulence factors in strains of photorhabdus bacteria

J Bacteriol. 2003 Aug;185(15):4648-56. doi: 10.1128/JB.185.15.4648-4656.2003.

Abstract

Photorhabdus is an insect-pathogenic bacterium in which oral toxicity to insects is found in two distinct taxonomic groups. Using a DNA microarray and comparative genomics, we show that oral toxicity is associated with toxin complex genes tcaABC and that this locus can be mobilized or deleted within different strains.
