Gram variable, 1.8-3.7/0.6-0.9 μm, motile bacillus. Peritrichous flagella.
Ellipsoidal, deforming spore located central or paracentral & positioned excentric
(lateral), conferring to the vegetative cell a letter C or canoe aspect. No capsule
present.

Isolated from water, honeybees larvae dead of’ European foulbrood and from the
healthy worker-bee intestine. Produces hetero- & auto-antibiotics.
healthy worker-bee intestine. Produces hetero- & auto-antibiotics.
Rather saprophytic bacteria, can intensively multiply in honeybees larvae dead of’
European foulbrood, its evolution resembling Paenibacillus alvei. Is a component of
associative flora in European foulbrood, probably more active in the last stages of the
disease.
