The infection of two Helicobacter pylori strains with a phage-containing supernate of the lysogenic H. pylori strain IMMi 290/89 resulted in a lytic cycle and propagation of phage HP1. In negatively-stained preparations, the empty phage heads measured 55-60 nm in diameter and mature heads measured 50 nm. The flexible, striated phage tail was c. 170 nm in length and 9.5 nm in diameter. The phage showed a mean density of 1.40 g/cm3 in sucrose-density gradients and contained double-stranded DNA c. 22,000 bp in length.
用溶原性幽门螺杆菌菌株IMMi 290/89的含噬菌体的上清液感染两种幽门螺杆菌菌株，导致噬菌体HP1的裂解循环和增殖。在负染制剂中，空噬菌体头部直径为55 - 60 nm，成熟头部直径为50 nm。柔性的、有条纹的噬菌体尾部长度约为170 nm，直径为9.5 nm。该噬菌体在蔗糖密度梯度中的平均密度为1.40 g/cm³，含有长度约为22,000 bp的双链DNA。
