From: Evaluation of mouse enteroids as a model for Lawsonia intracellularis infection
L. intracellularis infection in epithelial cells of mouse enteroids infected by the “incubation and seed” method. A L. intracellularis antigen is associated mostly with cell debris (arrow heads), ×200. B L. intracellularis antigen is associated with cell debris (arrow heads) and in close proximity to enteroid cells (black arrows), ×200. C L. intracellularis antigen is observed in close association with mouse enteroid cells (black arrows), ×200. D A few L. intracellularis antigens are observed in this image, some close to mouse enteroid cells (black arrow), and some associated with cell debris (arrow head), ×200. Enteroid lumen is indicated by an asterisk (*).
