Six related Staphylococcus phages spontaneously produced various abnormal head and tail structures: (i) giant capsids which were tailed and apparently contained nucleic acid; (ii) regular and irregular smooth polyheads; (iii) heads and polyheads with wavy outlines; (iv) mottled heads and polyheads; (v) abnormally long and short tails; and (vi) "double capsids" connected by a small bridge. Some of these structures are rare, or have not yet been reported. The frequency os specific aberrant particles varied from one phage to another. Length distribution of smooth irregular polyheads and of abnormal tails indicated that these structures assemble at random from protein synthesized in excess. These phages represent an interesting model for genetic and morphogentic studies.
（i）有尾的巨大衣壳，显然含有核酸；（ii）规则和不规则的光滑多面体头部；（iii）轮廓呈波浪状的头部和多面体头部；（iv）斑驳的头部和多面体头部；（v）异常长和短的尾部；以及（vi）通过小桥连接的“双衣壳”。其中一些结构很罕见，或者尚未见报道。特定异常颗粒的频率因噬菌体而异。光滑不规则多面体头部和异常尾部的长度分布表明，这些结构是由过量合成的蛋白质随机组装而成的。这些噬菌体代表了遗传和形态发生研究的一个有趣模型。
