Banana streak virus (BSV) is a badnavirus that causes a viral leaf streak disease of banana and plantain (Musa spp.). Identified in essentially all Musa growing areas of the world, it has a deleterious effect on the productivity of infected plants as well as being a major constraint to Musa breeding programmes and germplasm dissemination. Banana is a staple food in Uganda which is, per capita, one of the worlds largest banana producers and consumers. BSV was isolated from infected plants sampled across the Ugandan Musa growing area and the isolates were analysed using molecular and serological techniques. These analyses showed that BSV is very highly variable in Uganda. They suggest that the variability is, in part, due to a series of introductions of banana into Uganda, each with a different complement of infecting viruses.
香蕉条纹病毒（BSV）是一种杆状DNA病毒，可导致香蕉和大蕉（芭蕉属物种）出现病毒性叶斑病。在世界上几乎所有的芭蕉种植区都发现了这种病毒，它对受感染植物的生产力有有害影响，同时也是芭蕉育种计划和种质传播的主要制约因素。香蕉是乌干达的主食，该国是世界上人均香蕉产量和消费量最大的国家之一。从乌干达芭蕉种植区采集的受感染植物中分离出了BSV，并使用分子和血清学技术对分离株进行了分析。这些分析表明，BSV在乌干达具有高度变异性。它们表明，这种变异性部分是由于一系列香蕉被引入乌干达，每次引入时携带的感染病毒组合都不同。
