Approximately 2 500 specimens from 96 renal transplant recipients were examined for virus particles. Electron microscopy of negatively stained preparations showed that only 3 virus groups were present, namely polyomavirus, adenovirus and herpesvirus. No RNA viruses or oncogenic RNA viruses (retraviridae) were detected. Over a 5-year period polyomavirus was excreted by 37,5% of patients. Both herpesvirus and adenovirus were excreted by approximately 11% of the patients. Although trace quantities of other viruses may have been missed, the absence of RNA virus suggests that immunosuppressive treatment activates these DNA viruses. The failure to detect RNA viruses suggests that they are absent or may require different means of activation.
对96名肾移植受者的约2500份标本进行了病毒颗粒检测。对负染制剂进行电子显微镜检查显示，仅存在3种病毒组，即多瘤病毒、腺病毒和疱疹病毒。未检测到RNA病毒或致癌RNA病毒（逆转录病毒科）。在5年期间，37.5%的患者排出了多瘤病毒。约11%的患者排出了疱疹病毒和腺病毒。尽管可能遗漏了微量的其他病毒，但未检测到RNA病毒表明免疫抑制治疗激活了这些DNA病毒。未能检测到RNA病毒表明它们不存在或可能需要不同的激活方式。
