The fluorescence images on the top are the result of incubating second-stage infective juveniles of two species of root-knot nematode, Meloidogyne incognita and M. arenaria to an antibody conjugated to FITC that was raised against M. incognita. The antibody shows that the cuticle surface of these two species are immunologically very different. Pasteuria endospore attachment tests reveal that this difference is also functionally important in that different populations of endospores vary in their ability to attach to these two species of nematode. The 'Holy Grail' of diagnistics from an agricultural perspective is to develop tests that are predictive of a pathogen's host range.
