Seven novel tailed lytic viruses (Ds3CZ, Ds5CZ, Ds9CZ, Ds16CZ, Ds20CZ, Ds23CZ, Ds25CZ) infecting the bacterium Dickeya solani were isolated in the Czech Republic. Genomes of these viruses are dsDNA, 149,364 to 155,285 bp in length, and the genome arrangement is very similar to that of the type virus Dickeya virus LIMEstone 1. All but the Ds25CZ virus should be regarded as strains of a single species. Most of the sequence differences are due to the presence or absence of homing endonuclease (HE) genes, with 23 HEs found in Ds3CZ, Ds5CZ, and Ds20CZ, 22 in Ds9CZ, 19 in Ds16CZ, 18 in Ds25CZ, and 15 in Ds23CZ.
在捷克共和国分离到了 7 种新型尾部裂解病毒（Ds3CZ、Ds5CZ、Ds9CZ、Ds16CZ、Ds20CZ、Ds23CZ 和 Ds25CZ），它们感染细菌 Dickeya solani。这些病毒的基因组为 dsDNA，长度为 149364 到 155285bp，基因组排列与典型病毒 Dickeya virus LIMEstone 1 非常相似。除了 Ds25CZ 病毒之外，其余的都应该被视为单一物种的菌株。大多数序列差异是由于存在或不存在归巢内切酶（HE）基因所致，在 Ds3CZ、Ds5CZ 和 Ds20CZ 中发现了 23 个 HE，在 Ds9CZ 中发现了 22 个，在 Ds16CZ 中发现了 19 个，在 Ds25CZ 中发现了 18 个，在 Ds23CZ 中发现了 15 个。
