Histology and immunohistochemistry of right ventricle from two dogs with heartworm. Dog 1: (a–c) the asterisk points the presence of necrosis (a, H&E, 20×), which corresponded in the same area with a decreased staining for troponin I (b, immunostaining for troponin I, 20×) and myoglobin (c, immunostaining for myoglobin, 20×). (d–e) healthy myocardial tissue (d, H&E, 10×) and immunostaining of the same area where a consistent and uniform staining was observed (e, immunostaining for troponin I, 10×).
