Xanthomonas phaseoli pv. manihotis (Xpm) and X. cassavae (Xc) are two bacterial pathogens attacking cassava. Cassava bacterial blight (CBB) is a systemic disease caused by Xpm, which might have dramatic effects on plant growth and crop production. Cassava bacterial necrosis is a nonvascular disease caused by Xc with foliar symptoms similar to CBB, but its impacts on the plant vigour and the crop are limited. In this review, we describe the epidemiology and ecology of the two pathogens, the impacts and management of the diseases, and the main research achievements for each pathosystem. Because Xc data are sparse, our main focus is on Xpm and CBB.
菜豆细菌性疫病（Xpm）和木薯细菌性枯萎病（Xc）是两种攻击木薯的细菌病原体。由 Xpm 引起的木薯细菌性枯萎病是一种系统性疾病，可能对植物生长和作物产量产生巨大影响。木薯细菌性坏死病是一种非维管束疾病，由 Xc 引起，其叶片症状与 CBB 相似，但对植物活力和作物的影响有限。在这篇综述中，我们描述了两种病原体的流行病学和生态学、疾病的影响和管理，以及每个病理系统的主要研究成果。由于 Xc 的数据较为稀少，我们主要关注 Xpm 和 CBB。
