Dilated cardiomyopathy and amebic gastritis in a giant anteater (Myrmecophaga tridactyla).
An approximately 11-mo-old female giant anteater (Myrmecophaga tridactyla) exhibited anorexia, lethargy, hypothermia, depression, and minimal response to external stimuli. Radiography and ultrasonography revealed an enlarged heart, with free gas and fluid in the abdomen. Abdominocentesis produced a clear brown fluid with an acute to subacute septic suppurative exudate. Cardiac ultrasonography revealed a dilated, thin-walled left ventricle with a comparatively low fractional shortening. Despite intensive supportive care, the anteater died. Postmortem findings included gastric ulceration with perforation near the pylorus. Entameba spp. and Acanthamoeba spp. were both identified in large numbers at the site of the gastric ulceration and perforation.
