Pasteuria is a genus of mycelial and endospore-forming, nonmotile gram-positive bacteria that are obligate parasites of some nematodes and crustaceans.
[6] In water fleas, the ability of the endospore to successfully attach during the infection process is related to the genotype of the host and the parasite.
endospore germination usually occurs sometime between the nematode entering the root, setting up the feeding site and the first molt as currently there are no reports of second-stage juveniles (J2) of Meloidogyne spp.
Interestingly, endopores that do not infect water fleas and pass through a resistant host can still remain viable and infectious.
[15] In 2013, Syngenta launched CLARIVA™ pn, which has the active ingredient of Pasteuria nishizawae to combat the soybean cyst nematode.
