In an enclosure with nine collared peccaries (Pecari tajacu) from the Rio de Janeiro city Zoo, Brazil, one specimen was found dead and two others developed prostration, apathy and dehydration, resulting on its death. Necropsy of two animals pointed to pulmonary and renal damage. Histological examination revealed vasculitis in spleen from both P. tajacu, suggesting a systemic viral infection. Lungs from one specimen showed fibrinoid vasculitis, alveolar damage with hyaline membrane, and interstitial lymphocytes infiltration. Virome analysis in anal wash samples from the latter two animals revealed a new type of Betacoronavirus, lineage A, provisionally named Ptajacu-CoV. |
