Aspects of photosensitization in bovines grazing on pastures of Brachiaria decumbens Stapf infested with Pithomyces chartarum (Berk. & Curt.) M.B. Ellis infested all pastures 45(2):117-136, 1978. This paper reports experimental studies on photosensitization in bovines grazing on different pastures of Brachiaria decumbens Stapf in the "Cerrados" region (Planaltina, DF). Climatic conditions, zinc content and occurence of fungi on pastures were investigated. Pithomyces chartarum (Berk. & Curt.) M.B. Ellis infested all pastures examined. Photosensitization was observed in one animal maintained on a pasture of B. decumbens formed with seeds from Australia. Clinical and necropsy data were similar to those related in literature for sporidesmin-intoxicated animals. An isolate of P. chartarum and samples of bovine bile were assayed for sporidesmin presence.
在被炭疽状梨孢霉（Berk. & Curt.）M.B. 埃利斯侵染的俯仰臂形草（Brachiaria decumbens Stapf）牧场上放牧的牛的光敏化情况，侵染了所有牧场，《巴西农业研究》45(2):117 - 136，1978年。本文报道了在“塞拉多斯”地区（巴西联邦区普拉纳蒂纳）不同俯仰臂形草牧场上放牧的牛的光敏化实验研究。对牧场的气候条件、锌含量和真菌发生情况进行了调查。炭疽状梨孢霉（Berk. & Curt.）M.B. 埃利斯侵染了所有检查的牧场。在一头以来自澳大利亚种子形成的俯仰臂形草牧场饲养的动物身上观察到了光敏化。临床和尸检数据与文献中关于孢霉毒素中毒动物的相关数据相似。对一株炭疽状梨孢霉分离株和牛胆汁样本进行了孢霉毒素存在情况的检测。
