Vb-AphaS-CL131 is a novel cyanosiphovirus that infects harmful Aphanizomenon flos-aquae. This cyanophage has an isometric head, 97 nm in diameter and a long, flexible non-contractile tail, 361 nm long. With a genome size of ~120 kb, it is the second largest cyanosiphovirus isolated to date. The latent period was estimated to be ~36 h and a single infected cell produces, on average, 218 infectious cyanophages. Cyanophage infection significantly suppresses host biomass production and alters population phenotype.
Vb-AphaS-CL131是一种新型的蓝藻病毒，可感染有害的水华束丝藻。这种噬藻体有一个直径97纳米的等轴状头部和一条长361纳米的、细长且可弯曲的非收缩性尾部。其基因组大小约为120 kb，是迄今为止分离出的第二大蓝藻病毒。潜伏期估计约为36小时，单个受感染细胞平均产生218个有感染性的噬藻体。噬藻体感染显著抑制宿主生物量的产生并改变群体表型。
