Description:Prepared using the Brown & Brenn method of staining, and under a magnification of 125X, this photomicrograph reveals histopathologic changes indicative of the presence of the Gram-positive, rod-shaped bacteria, Arachnia propionica.
Arachnia propionica has now been renamed as Propionibacterium propionicus, and has been found to be one of the causative agents in the disease actinomycosis. See PHIL 4201, and 4217 for two additional views of this granule at under successively greater magnifications.
