Shigella fiexneri phage SGF2 is a novel lytic phage isolated from a sewage sample. Morphological characterization indicates that phage SGF2 is a member of the Podoviridae family, producing virions with an isometric head (82.6 ± 8 nm diameter) and a short non-contractile tail (length 52 ± 8 nm). This phage specifically infected the Shigella fiexneri. One-step growth curves indicated that the burst period of phage SGF2 is 30 min, with an approximate burst size of 38. The full-length genome was sequenced and potential virulence genes were detected. We will discuss the potential application of phage SGF2 in phage therapy.

感染 Shigella fiexneri 并从污水中分离的新型毒力噬菌体的基因组特征。

Shigella fiexneri 噬菌体 SGF2 是一种从污水样品中分离出来的新型裂解噬菌体。形态学特征表明噬菌体 SGF2 是 Podoviridae 家族的成员，产生具有等距头部（直径 82.6 ± 8 nm）和短的非收缩尾（长度 52 ± 8 nm）的病毒粒子。这种噬菌体专门感染了志贺氏菌。一步生长曲线表明噬菌体SGF2的爆发期为30 min，爆发期约为38。对全长基因组进行测序并检测到潜在的毒力基因。我们将讨论噬菌体 SGF2 在噬菌体治疗中的潜在应用。
