Progressive wasting was observed in 4/1000 steers grazing Brachiaria decumbens pastures. Yellow liver and whitish hard nodules in the mesenteric and hepatic lymph nodes were observed at necropsy. At histologic examination multifocal accumulation of foamy macrophages were in the livers, spleens, lmph nodes, and intestinal submucosa. It is suggested that the wasting syndrome was due to the intestinal granulomatous lesions of B decumbens.
在1000头放牧于俯仰臂形草牧场的公牛中，观察到4头发病牛出现进行性消瘦。尸检时发现肝脏发黄，肠系膜和肝淋巴结有白色硬结节。组织学检查发现，肝脏、脾脏、淋巴结和肠黏膜下层有多处泡沫状巨噬细胞聚集。提示消瘦综合征是由俯仰臂形草的肠道肉芽肿性病变引起的。
