shed reasonable
doubt on the correct classification of the species.
Consequently, the most recent revision of this species led to the
reclassification of the subspecies P. l. larvae and P. l. pulvifaciens as
one species P. larvae without subspecies differentiation. Classical
methods (colony morphology, electron microscopical analysis of
spore morphology) and state-of-the-art molecular methods like
pulsed-field gel electrophoresis (PFGE), protein profiling via SDS–
PAGE analysis, and repetitive-element PCR (rep-PCR)
