Histopathological kidney changes and myoglobinuria in neotropical non-human primates attacked by dogs, Brazil.

Background: Non-human primates (NHPs) are susceptible to dogs' attacks, events that may cause muscle damage along with stress, and could be in some extent compatible with capture myopathy, a syndrome that results in myoglobinuria and renal damage.

Methods: We aimed to evaluate by histopathology pre-existing lesions and subsequent sequelae related to dogs' attacks, acute tubular necrosis (ATN) and myoglobinuria, as well as the usefulness of Pearls Stain and IHC to diagnose it. Histopathology was performed in available organs, and sections of kidney submitted to Prussian blue stain and myoglobin immunohistochemistry.
