Immunohistochemistry of the surface endometrial epithelium of a heifer 6 weeks after experimental infection with 106 T. foetus at estrus. Stained with mAb TF1.15 (specific for TF 1.17 antigen) and developed with peroxidase conjugate. Note the antigen uptake by epithelial cells with intense staining at the apical surface. Intraepithelial plus subepithelial lymphocytes are also detected.
