新的分子生物学技术,特别是代表性差异分析、基于共识序列的聚合酶链式反应和互补DNA文库筛选,已经导致了几种以前无法培养的感染性病原体的鉴定。在卡波西氏肉瘤、非甲型、非乙型肝炎、汉坦病毒肺综合征、杆状血管瘤病和惠普尔病患者的组织中发现了新的药物,这些技术不需要直接培养。新方法依赖于从可疑病原体中识别亚基因组片段。在从疾病组织中分离出属于某一病原体的唯一核酸片段后,可以对该片段进行测序,并将其用作探针,以识别其他感染组织或获得该病原体基因组的扩展部分。对于不能用标准技术培养的试剂,这些方法被证明对于鉴定和表征研究是非常有价值的。将这些技术应用于其他疑似感染病原学的人类疾病,可能会迅速阐明新的候选病原体。
New molecular biologic techniques, particularly representational difference analysis, consensus sequence-based polymerase chain reaction, and complementary DNA library screening, have led to the identification of several previously unculturable infectious agents. New agents have been found in tissues from patients with Kaposi's sarcoma, non-A, non-B hepatitis, hantavirus pulmonary syndrome, bacillary angiomatosis, and Whipple's disease by using these techniques without direct culture. The new methods rely on identifying subgenomic fragments from the suspected agent. After a unique nucleic acid fragment belonging to an agent is isolated from diseased tissues, the fragment can be sequenced and used as a probe to identify additional infected tissues or obtain extended portions of the agent's genome. For agents that cannot be cultured by standard techniques, these approaches have proved invaluable for identification and characterization studies. Applying these techniques to other human diseases of suspected infectious etiology may rapidly elucidate novel candidate pathogens.
