Plaque-purified and non-plaque-purified velogenic viscerotropic Newcastle disease viruses (VVNDVs) were inoculated into golden-mantled rosellas (Platycercus eximius). VVNDV produced acute clinical disease in this species: all birds died within 6 days postexposure. There was no difference between the two inoculation groups in clinical signs. Seven tissues and five tissue swabs were collected from each of 15 birds. The VVNDV concentration in each specimen was titrated, and the concentrations were compared. The lung and trachea had the highest concentrations of virus in both the tissue suspensions and the swab suspensions. The average virus concentrations of the lung were 10(5.9) 50% embryo lethal doses (ELD50) per 0.1 ml for the tissue suspension and 10(4.9) for the swab. The average virus concentrations of the trachea were 10(5.6) ELD50 per 0.1 ml of tissue suspension and 10(4.6) for the swab.
将经蚀斑纯化和未经蚀斑纯化的速发型嗜内脏型新城疫病毒（VVNDV）接种到金披风玫瑰鹦鹉（Platycercus eximius）体内。VVNDV在该物种中引发了急性临床疾病：所有鸟类在接触后6天内死亡。两个接种组在临床症状上没有差异。从15只鸟中每只采集了7种组织和5份组织拭子。对每个样本中的VVNDV浓度进行了滴定，并对浓度进行了比较。在组织悬液和拭子悬液中，肺和气管中的病毒浓度最高。肺组织悬液中每0.1 ml的平均病毒浓度为10(5.9) 50%胚致死剂量（ELD50），拭子中的平均病毒浓度为10(4.9)。气管组织悬液中每0.1 ml的平均病毒浓度为10(5.6) ELD50，拭子中的平均病毒浓度为10(4.6)。
