Fibro-purulent bronchopneumonia and chronic kidney disease (CKD) in the antillean manatee (trichechus manatus manatus L. 1758)

Abstract

The aim of this study was to present a first case of fibro-purulent pneumonia and chronic kidney disease in the Antillean manatee. The 23-yr-old female of Antillean manatee (Therese von Bayern) was moved from the Tierpark Berlin (Germany) to the Wroclaw Zoological Garden (Poland), on the 15th of December 2014. The manatee died on the 4th of April 2015. Postmortem examination revealed the right lung dark red lesions indicative of pulmonary congestion and extravasations. There was a fist-sized cavity filled with a bloody fluid and fragments of lung tissue at one-third of the length of that lung. Both kidneys with no pathologic changes, pale pink, with fragile structure. Histopathologic examination revealed fibro-purulent bronchopneumonia, interstitial renal fibrosis, nephritis and glomerulonephritis with protein deposits and acute tubular necrosis (ATN), hepatic fibrosis and hepatocellular degeneration. The lung tissue expressed cytokeratin, vimentin and a CD68 macrophage marker.
