Three outbreaks of hepatogenous photosensitization caused by pods of Enterolobium contortisiliquum are reported in cattle. Clinical signs were anorexia, depression, photosensitization and abortion. Most affected cattle recovered in 30-40 d. At necropsies, liver was present, the gallbladder was enlarged and edematous, and numerous seeds of E contortisiliquum were in the forestomachs and abomasum. Fruits of the plants administrated to 2 calves produced clinical signs and 2/4 died. Clinical chemistry, gross necropsies and histopathology confirmed gastrointestinal irritation and liver degeneration. One calf dosed with only E contortisiliquum leaves did not develop clinical signs.
据报道,牛群中发生了三起因卷曲豆荚引起的肝源性光敏反应疫情。临床症状为厌食、抑郁、光敏反应和流产。大多数受影响的牛在30至40天内康复。尸检时,肝脏存在,胆囊肿大且水肿,前胃和皱胃中有大量卷曲豆种子。给2头犊牛投喂该植物果实出现了临床症状,其中2/4死亡。临床化学、大体尸检和组织病理学证实存在胃肠道刺激和肝脏变性。1头仅投喂卷曲豆叶子的犊牛未出现临床症状。
