概括

在腐烂的尸体中诊断疟疾是困难的. 实时PCR (RT-PCR) 成功检测到巴尔萨姆化尸体器官中的Plasmodium falciparum DNA,证实致命的脑疟疾.

科学领域:

法医病理学法医病理学
传染性疾病传染性疾病
分子诊断学分子诊断

背景情况:

在腐烂或防腐尸体中诊断疟疾存在重大挑战,原因是非特异性的宏观发现和生物样本的退化.
传统的诊断方法,如血涂片检查和快速免疫染色学测试,在死后病例中通常是不可行的,因为病例的分解或长时间存储已晚.

研究的目的:

调查实时聚合酶连锁反应 (RT-PCR) 实时聚合酶连锁反应 (RT-PCR) 的实用性,以诊断致命的脑疟疾,在一个涉及长期储存和防腐尸体的具有挑战性的法医病例中.
为了确定23岁的白人男性死亡的原因,他曾经去过非洲.

主要方法:

在一个尸体上进行了法医解剖,该尸体在最初的尸体解剖后被调解并储存了8.5个月.
从各种内部器官中提取遗传物质,包括大脑,心脏,肺部,脏,肝脏和脏.
实时聚合酶连锁反应 (RT-PCR) 用于在提取的样本中检测Plasmodium falciparum DNA.

主要成果:

在来自大脑,肺部,脏,肝脏和脏的样本中成功识别了Plasmodium falciparum遗传物质.
这些器官中寄生虫DNA的存在证实了疟疾的诊断.

结论:

实时PCR (RT-PCR) 是一种可行且有效的方法来诊断疟疾,包括致命的大脑疟疾,在涉及腐烂和化尸体的挑战性死后病例中.
这种分子技术克服了传统方法的局限性,使得在保存的组织中能够准确识别Plasmodium DNA.

Malaria

Malaria pathogenesis in humans reflects a delicate interplay between parasite biology and host response. Clinical illness reflects a host’s immune response to the parasite’s asexual replication cycle, which is often asymptomatic in individuals with partial immunity. From the parasite's perspective, transmission between mosquito and human with minimal host pathology is evolutionarily advantageous. Among the six Plasmodium species infecting humans, P. falciparum and P. vivax dominate in global...
