a. The explanted lens capsule contains lens cortical material with granular bacterial colonies (asterisks), and a sparse focal inflammatory infiltrate. b. High-magnification photomicrograph highlights the organisms (arrow), associated with a subacute inflammation. c. Gram stain confirms the presence of Gram-positive coccobacilli, focally in the cytoplasm of inflammatory cells. d. A large colony of Gram-positive pleomorphic coccobacilli is present within the cataractous lens material, unassociated with inflammatory reaction.
