柠檬酸黄单胞菌的温带噬菌体经氯仿处理后完全失活，而毒性噬菌体对氯仿处理则相当稳定。大约80%（但不是全部）的广泛系列柑橘X.分离物被噬菌体Cp1裂解。Cp2，或者两者都有。43种黄单胞菌136株分离株中，7种黄单胞菌仅分离9株[X]。秋海棠（XB8, XB111）、双头棘球绦虫（XB115）、葫芦棘球绦虫（XC6）、phaseoli棘球绦虫（XP4, Xph）、phaseoli变种sojense棘球绦虫（XP21）、marantae棘球绦虫（XM126）、translucens棘球绦虫phleum-pratense棘球绦虫（XT103）)对柑橘棘球绦虫的噬菌体均有敏感性。Stolp-Starr噬菌体之一ph25对几乎所有柑橘X.菌株以及许多其他黄单胞菌都有裂解反应。黄单胞菌与不同来源的噬菌体的交叉敏感性试验表明，黄单胞菌噬菌体通常可以在土壤中形成针尖大小的小斑块，并且它们的宿主范围非常广泛，不仅可以在同一种的不同菌株中发现，也可以在许多异源的菌株中发现。相比之下，从患病植物组织中分离的黄单胞菌噬菌体通常具有非常有限的宿主范围。
The temperate phages of Xanthomonas citri are completely inactivated by chloroform treatment, whereas the virulent phages are quite stable to the treatment. About 80 percent (but not all) of an extensive series of X. citri isolates is lysed by phage Cp1. Cp2, or both. Among 136 isolates of 43 Xanthomonas nomenspecies, only 9 isolates belonging to 7 nomenspecies [X. begoniae (XB8, XB111), X. blepharidis (XB115), X. cucurbitae (XC6), X. phaseoli (XP4, Xph), X. phaseoli var. sojense (XP21), X. marantae (XM126), and X. translucens f. sp. phleum-pratense (XT103)] showed susceptibility to any of the X. citri phages. One of the Stolp-Starr phages, ph25, showed lytic reactions on almost all isolates of X. citri, as well as on many other Xanthomonas nomenspecies. From the cross-susceptibility tests between Xanthomonas bacteria and various phages from different sources, it was concluded that, in general, the Xanthomonas phages which form tiny plaques of pinhead size could frequently be found in soil, and that they showed very broad host ranges, which extended not only over the different isolates of a homologous nomenspecies but also over strains of many heterologous nomenspecies. In contrast, the Xanthomonas phages which were isolated from diseased plant tissues usually showed very limited host ranges.
