Abstract
Four alpine goats developed diarrhea soon after the owner placed plant clippings believed to be yellow oleander (Thevetia peruviana) into their pen on a suburban property near Palm Desert, CA, USA. A 1-y-old female goat died suddenly ~1 h after eating the plant clippings and was submitted to the San Bernardino Branch of the California Animal Health and Food Safety Laboratory System for postmortem examination. The main autopsy and histopathologic findings were myocardial hemorrhage and necrosis, consistent with cardiac glycoside intoxication. Rumen contents were analyzed by LC-MS/MS; peruvoside, a cardiac glycoside, was detected, but oleandrin, the cardiac glycoside of common oleander (Nerium oleander), was not. An LC-high-resolution MS (LC-HRMS) analysis revealed the presence of peruvoside and neriifolin in the rumen contents and in a tested plant fragment, indicating that the plant was a member of the Thevetia genus. A clipping from the plant fed to the goats and submitted by the owner was identified as yellow oleander, Thevetia peruviana (also known as Cascabela thevetia).
