An extensive survey was carried out in the Dominican Republic in order to monitor the prevalence of the three most widespread BSV species: Banana streak OL virus (BSOLV), Banana streak GF virus (BGFV) and Banana streak IM virus (BSIMV), in Macho x Hembra (MxH) and FHIA-21 plantains and in Cavendish dessert banana throughout all banana-producing areas. This survey led to the first detection of BSVs in the Dominican Republic. BSGFV was the most prevalent of the three targeted BSV species in both FHIA-21 and MxH varieties. Prevalence of BSGFV and BSOLV were substantially higher in FHIA-21 than in MxH. Molecular analysis of the eBSV pattern of sampled FHIA-21 and MxH plants showed that both varieties harbor infectious alleles OL1 (eBSOLV) and GF7 (eBSGFV) and are devoid of eBSIMV. Very low prevalence was recorded for both BSOLV and BSGFV in Cavendish banana, which is devoid of infectious eBSVs. BSIMV was not detected at all. Our results point to a marginal role of insect-borne transmission in the epidemiology of BSVs in the Dominican Republic.

多米尼加共和国香蕉条纹病毒的流行率和多样性

在多米尼加共和国进行了一项广泛的调查，以监测三种最普遍的 BSV 物种：香蕉条纹 OL 病毒 (BSOLV)、香蕉条纹 GF 病毒 (BGFV) 和香蕉条纹 IM 病毒 (BSIMV) 在 Macho x Hembra (MxH) 和 FHIA-21 大蕉以及所有香蕉产区的卡文迪什甜点香蕉。这项调查导致在多米尼加共和国首次发现 BSV。BSGFV 是 FHIA-21 和 MxH 品种中三种靶向 BSV 物种中最流行的。FHIA-21 中 BSGFV 和 BSOLV 的患病率明显高于 MxH。FHIA-21 和 MxH 植物样本的 eBSV 模式的分子分析表明，这两个品种都含有传染性等位基因 OL1 (eBSOLV) 和 GF7 (eBSGFV)，并且没有 eBSIMV。在没有传染性 eBSV 的卡文迪什香蕉中，BSOLV 和 BSGFV 的流行率都非常低。根本没有检测到 BSIMV。我们的研究结果表明，昆虫传播在多米尼加共和国 BSV 的流行病学中的作用微乎其微。
