The two canine adenoviruses, infectious canine hepatitis (ICH) virus and infectious canine laryngotracheitis (ICL) virus (also designated as Toronto A26/61 virus), were studied with respect to their morphology and the biological properties of their soluble components. The two viruses were found to be composed of soluble components similar to, and carrying biological activities corresponding to, those of the human adenoviruses after fractionation by rate zonal centrifugation and anion-exchange chromatography. The following soluble components were identified: hexons (carrying a common group-specific complement-fixing antigen), penton oligomers (complete soluble hemagglutinin), and penton and fiber monomers (incomplete soluble hemagglutinins). The latter were indicated by hemagglutination enhancement with selected antisera directed against human adenovirus soluble components. Elution characteristics of corresponding components of the two viruses in anion-exchange chromatography experiments were distinctly different. Electron microscopic examination of purified virions and soluble components revealed the fiber component of ICL virus to be 35 to 37 nm in length, and that of ICH virus to be 25 to 27 nm long.
对两种犬腺病毒,即犬传染性肝炎(ICH)病毒和犬传染性喉气管炎(ICL)病毒(也称为多伦多A26/61病毒),就其形态以及可溶性成分的生物学特性进行了研究。通过速率区带离心和阴离子交换色谱法分级分离后发现,这两种病毒的可溶性成分与人类腺病毒的相似,并具有与之对应的生物学活性。鉴定出了以下可溶性成分:六邻体(携带共同的群特异性补体结合抗原)、五邻体寡聚体(完整的可溶性血凝素)以及五邻体和纤维单体(不完整的可溶性血凝素)。针对人类腺病毒可溶性成分的特定抗血清通过血凝增强作用表明了后者的存在。在阴离子交换色谱实验中,两种病毒相应成分的洗脱特性明显不同。对纯化病毒粒子和可溶性成分的电子显微镜检查显示,ICL病毒的纤维成分长度为35至37纳米,ICH病毒的纤维成分长度为25至27纳米。
