非人灵长类结核病的诊断方法及进展

目前非人灵长类结核病的诊断方法单一,给饲养和管理带来影响。通过总结和讨论人的结核病诊断技术,结合非人灵长类的实际情况,指出在结核病检疫中,虽然结核菌素是经典的早期诊断的方法,但血清抗体的检测是结核菌素试验的有效辅助手段,尤其对无反应猴群的结核病检测具有独特的优势。然而,IFNγ的检测有望替代结核菌素试验,实现体外检测结核病。传统的结核菌培养技术时间长,假阴性多,污染率高,给猴的结核病的确诊带来困难。原位PCR技术,能加快诊断速度,提高检出率,特别有利于对小病灶区的病源诊断。虽然目前该技术还不能替代细菌学诊断技术,但两种方法的有效结合将有利于提高非人灵长类的结核病的病源诊断。

Evolvement of Diagnostic Tools for Primates Tuberculosis

In order to detect rodent coronavirus, a pair of PCR primers were designed according to the compared sequences of rodent coronavirus and SARS coronavirus. The primers derived from the specific and conservative N gene , RT-PCR method was established. Result of rodent RT-PCR amplification showed the amplified products of 148bp length; RT-PCR method of rodent coronavirus has been used to detect the samples. The rodent RT-PCR method is important to determine early rodent coronavirus and discriminate SARS coronavirus.
