We document columbid herpesvirus-1 (CoHV-1) infection in two barking owls (Ninox connivens), a powerful owl (Ninox strenua) and an Australian hobby (Falco longipennis). Antemortem signs of infection were non-specific and the birds either died soon after they were identified as ill or were found dead unexpectedly. Gross postmortem findings were also not specific. Microscopically, marked to massive splenic and hepatic necrosis with the presence of eosinophilic inclusion bodies in remaining splenocytes and hepatocytes was found in all birds. Herpesvirus virions were identified in liver sections from one of the boobook owls by electron microscopy. Using CoHV-1-specific primers and polymerase chain reaction, CoHV-1 DNA was amplified from tissue samples from all birds. A comparison of these sequences to previously reported sequences of CoHV-1 found them to be identical or to vary by a single base pair. These findings increase the number of known species of birds of prey that are susceptible to CoHV-1 infection and indicate that rock pigeons (Columbia livia) should not be included in the diet of captive Australian birds of prey.
我们记录了两只斑林鸮（Ninox connivens）、一只猛鹰鸮（Ninox strenua）和一只澳大利亚侏隼（Falco longipennis）感染鸽疱疹病毒1型（CoHV-1）的情况。感染的生前症状不具特异性，这些鸟类在被认定生病后不久便死亡，或者意外死亡。死后大体检查结果也不具特异性。显微镜检查发现，所有鸟类均出现明显至大面积的脾脏和肝脏坏死，剩余脾细胞和肝细胞中存在嗜酸性包涵体。通过电子显微镜在一只林斑小鸮的肝脏切片中鉴定出疱疹病毒颗粒。使用CoHV-1特异性引物和聚合酶链反应，从所有鸟类的组织样本中扩增出CoHV-1 DNA。将这些序列与先前报道的CoHV-1序列进行比较，发现它们完全相同或仅相差一个碱基对。这些发现增加了已知易感染CoHV-1的猛禽种类数量，并表明圈养的澳大利亚猛禽的饮食中不应包含岩鸽（Columbia livia）。
