Some characteristics of Bacillus subtilis phage SPO2 which show that it is a temperate phage are presented. Wild-type SPO2 forms turbid plaques, similar to those of other temperate phages. SPO2 lysogenic strains which are resistant to SPO2 can be isolated; these strains remain stable lysogens despite the fact that they can no longer adsorb SPO2. SPO2 lysogenic strains can be grown for many generations in SPO2 antiserum and remain lysogenic. Phage SPO2 plates on phi105 lysogens and phage phi105 plates on SPO2 lysogens; this indicates that SPO2 and phi105 are heteroimmune. Phage phi105 plates on an SPO2-resistant strain; this indicates that SPO2 and phi105 adsorb to different receptor sites on the bacterial surface.
本文介绍了枯草芽孢杆菌噬菌体SPO2的一些特性，这些特性表明它是一种温和噬菌体。野生型SPO2形成浑浊噬菌斑，类似于其他温和噬菌体的噬菌斑。可以分离出对SPO2具有抗性的SPO2溶原性菌株；尽管这些菌株不再能吸附SPO2，但它们仍保持稳定的溶原状态。SPO2溶原性菌株可以在SPO2抗血清中传代培养多代并保持溶原状态。噬菌体SPO2能在phi105溶原菌上形成噬菌斑，而噬菌体phi105能在SPO2溶原菌上形成噬菌斑；这表明SPO2和phi105是异免疫的。噬菌体phi105能在对SPO2有抗性的菌株上形成噬菌斑；这表明SPO2和phi105吸附在细菌表面的不同受体位点上。
