Phages, viruses targeting bacteria, have potential therapeutic applications in the control of infections with antibiotic-resistant bacteria. In this study, an Enterobacter cloacae phage, Ec_L1, was isolated from sewage sludge samples collected from a hospital. The genome of phage Ec_L1 consists of 51,894 bp with 48.24% G+C content. Nineteen of the 85 putative proteins encoded by this phage have known functions, and no rRNA or tRNA genes were found. Comparative analysis of genome sequences suggested that phage Ec_L1 should be considered a member of the subfamily Tunavirinae, which includes T1-like phages. According to the International Committee on Taxonomy of Viruses (ICTV), phage Ec_L1 is the type member of the new genus “Eclunavirus”, whose name was derived from Ec_L1.

噬菌体是针对细菌的病毒，在控制抗生素抗性细菌的感染方面具有潜在的治疗应用。在这项研究中，从医院收集的污水污泥样本中分离出了阴沟肠杆菌噬菌体Ec_L1。噬菌体Ec_L1的基因组由51,894 bp组成，G + C含量为48.24％。该噬菌体编码的85种推定蛋白中有19种具有已知功能，没有发现rRNA或tRNA基因。基因组序列的比较分析表明，噬菌体Ec_L1应该被视为Tunavirinae亚家族的成员，该家族包括T1样噬菌体。根据国际病毒分类学委员会（ICTV）的研究，噬菌体Ec_L1是“埃克卢病毒”这一新属的类型成员。”，其名称源自Ec_L1。
