More than 796 Ascaris lumbricoides worms weighing 550 g were recovered at autopsy from a 2-year-old black South African girl. Most of the worms were taken from necrotic small intestine, but worms were also in the stomach, esophagus, intrahepatic and extrahepatic bile ducts, and gallbladder. The worms had caused torsion and gangrene of the ileum, which was interpreted as the cause of death. Worms were formalin-fixed and individually weighed. There were 796 intact worms and 112 appreciably large (greater than 0.2 g) fragments of worms. Statistical analysis of the weights revealed 2 distinct populations of worms: 16 large worms (0.5-2.3 g) and 778 small worms (0.03-0.95 g). The difference in weight between these 2 groups of worms was significant (male and female worms treated separately; P less than 0.05 to P less than 0.001). These observations reveal that the patient acquired a massive and fatal infection with A. lumbricoides while hosting a relatively burden.
在尸检时,从一名2岁南非黑人女孩体内取出了796条以上重550克的蛔虫。大多数蛔虫取自坏死的小肠,但胃、食管、肝内和肝外胆管以及胆囊中也有蛔虫。这些蛔虫导致了回肠扭转和坏疽,这被认为是死亡原因。蛔虫用福尔马林固定并分别称重。有796条完整的蛔虫和112块明显较大(大于0.2克)的蛔虫碎片。对重量的统计分析显示有两类不同的蛔虫群体:16条大蛔虫(0.5 - 2.3克)和778条小蛔虫(0.03 - 0.95克)。这两组蛔虫的重量差异显著(雌雄蛔虫分别处理;P小于0.05至P小于0.001)。这些观察结果表明,该患者在感染相对较轻时感染了大量致命的蛔虫。
