Evaluation of immunohistochemistry and microscopic lesions. At 14, 21 and 28 dpi immunohistochemistry (IHC) was performed to semi-quantify L. intracellularis in tissue and hematoxylin and eosin (HE) stain was performed to evaluate microscopic lesions. IHC scores used were of 0: absence of antigen in tissue; 1: 0–25%, 2: 25–50%; 3: 50–75%; 4: 75–100% of enteric crypts containing L. intracellularis antigen. HE scores used were of 1: focal lesions; 2: multifocal lesions; 3: diffuse lesions. A IHC score per time point after infection. B Percent of animals with microscopic lesions evaluated by HE. C HE score per time point after infection. Different letters indicate statistical significance (p < 0.05), error bars represent the standard error.
