Horses develop severe and often fatal hemolytic anemia after ingesting dried leaves from red maple (Acer rubrum) trees. Toxicosis appears related to an unknown oxidant present in the dried or wilted leaves. This case report describes 2 horses that aborted and developed fatal hemolytic anemia after consuming wilted leaves from red maple (Acer rubrum). While an absolute diagnosis was not confirmed due to lack of proper antemortem and postmortem examinations, red maple toxicosis appeared a reasonable diagnosis based on clinical signs and laboratory findings. Other differentials include equine infectious anemia, autoimmune hemolytic anemia, piroplasmosis, leptospirosis, ehrlichiosis, and other plant or chemical sources of oxidants (onion, garlic, kale, phenothiazines).
马匹在摄入红枫树（Acer rubrum）的干叶后会患上严重且往往致命的溶血性贫血。中毒似乎与干叶或枯萎叶片中存在的一种未知氧化剂有关。本病例报告描述了2匹马在食用红枫树（Acer rubrum）的枯萎叶片后流产并患上致命的溶血性贫血。由于缺乏适当的生前和死后检查，未能确诊，但基于临床症状和实验室检查结果，红枫中毒似乎是一个合理的诊断。其他鉴别诊断包括马传染性贫血、自身免疫性溶血性贫血、梨形虫病、钩端螺旋体病、埃立克体病以及其他植物或化学来源的氧化剂（洋葱、大蒜、羽衣甘蓝、吩噻嗪）。
