Four genotypes of the psittacid herpesvirus (PsHV) cause Pacheco disease in parrots. Viruses that are serologically cross-reactive to the PsHVs have also been isolated from passerine species. DNA was amplified from a herpesvirus isolated from a superb starling (Lamprotornis superbus) with PsHV-specific primers and polymerase chain reaction. A comparison of the partial sequence of the UL 16 gene from this herpesvirus with sequences from viruses of known PsHV genotypes showed that the herpesvirus from the superb starling was a PsHV genotype 1 virus. This finding expands the range of birds that are known to be susceptible to PsHV genotype 1 infections and suggests that PsHVs should be considered as a differential in passerines with herpesvirus infections.
鹦鹉疱疹病毒（PsHV）的四种基因型可导致鹦鹉患帕切科病。在雀形目鸟类中也分离出了与PsHVs血清学交叉反应的病毒。用PsHV特异性引物和聚合酶链反应从一只超级椋鸟（Lamprotornis superbus）分离出的疱疹病毒中扩增出DNA。将该疱疹病毒UL 16基因的部分序列与已知PsHV基因型病毒的序列进行比较，结果表明超级椋鸟的疱疹病毒是PsHV基因型1病毒。这一发现扩大了已知易感染PsHV基因型1的鸟类范围，并表明在患有疱疹病毒感染的雀形目鸟类中应将PsHVs视为一种鉴别诊断因素。
