Electron microscopical examination of the new virulent bacteriophage phi KZ, specific for Pseudomonas aeruginosa, has revealed an unusual structure in its capsid. In the center of the phage head is a cylinder of low electron density ("inner body"), surrounded by fibrous material which is packed around the inner body in a spoollike manner. The inner body itself has a springlike appearance. These structures disappear after adsorption of phage particles to bacteria. Various morphological forms, which can be interpreted as intermediate steps in phi KZ DNA condensation, have been seen in ultrathin sections of phi KZ-infected cells.
对特异性针对铜绿假单胞菌的新型烈性噬菌体phi KZ进行电子显微镜检查，发现其衣壳结构异常。在噬菌体头部中央是一个电子密度低的圆柱体（“内部体”），周围是纤维状物质，这些物质以卷轴状围绕内部体堆积。内部体本身呈弹簧状外观。噬菌体颗粒吸附到细菌上后，这些结构消失。在phi KZ感染细胞的超薄切片中观察到了各种形态形式，可将其解释为phi KZ DNA浓缩的中间步骤。
