BACKGROUND: An adult male Brachyteles arachanoides, kept in captivity since 1990, was found dead without apparent clinical evidence. METHODS: Necropsy report, histopathology, immunohistochemistry, and ultrastructural examination were conducted. RESULTS: Pulmonary syncytial cells were positive for respiratory syncytial virus (RSV), and ultrastructural examination revealed viral particles inside macrophages compatible with the Paramyxoviridae family. CONCLUSIONS: Muriquis are susceptible to RSV pneumonia followed by respiratory distress syndrome and death.
