  1. Data represent mean scores (± SD) for IHC staining and histopathological changes at each time of sampling (n = 5) shown for the inoculated (A) and cohabitant group (B). The IHC staining was performed with both Anti-σ1 and Anti-μ1C and scored (0-5) for positive leukocyte-like cells and cardiomyocytes. The histological changes were scored (0-3) for epicardial- and myocardial changes.
