已经确定了73个感染细菌肠杆菌科成员的尾状芽孢杆菌的全基因组序列。生物学标准，如基因组大小，基因组织和基因方向被用来把这些物种分类。有13个这样的类别，其中一些本身就非常多样化。讨论了这些类别之间和内部的关系，重点是头部组装基因。虽然它们中的一些显然是同源的，表明一个非常古老的起源，有很少的证据表明这些噬菌体类别之间的个别头部基因的交换。最近的水平交换噬菌体尾纤维和早期蛋白质之间的类别发生，但可能不是非常迅速。(C)2008年，Elsevier Masson SAS。所有的战斗保留。
Complete genome sequences have been determined for 73 tailed-phages that infect members of the bacterial Enterobacteriaceae family. Biological criteria such as genome size, gene organization and gene orientation were used to place these phages into categories. There are 13 such categories, some of which are themselves extremely diverse. The relationships between and within these categories are discussed with an emphasis on the head assembly genes. Although some of them are clearly homologues, suggesting a very ancient origin, there is little evidence for exchange of individual head genes between these phage categories. More recent horizontal exchange of phage tail fiber and early proteins between the categories occurs, but is probably not extremely rapid. (C) 2008 Elsevier Masson SAS. All fights reserved.
