澳大利亚的研究发现,Giardia寄生虫在人体中性繁殖,有助于传播和抗药。 Australian study finds Giardia parasite reproduces sexually in humans, aiding spread and drug resistance.

由澳大利亚牵头的研究表明,每年造成数百万感染的Giardia寄生虫在性和非性方面繁殖,解决了长达几十年的科学辩论。 Australian-led research has revealed that the Giardia parasite, which causes millions of infections annually, reproduces both sexually and asexually, resolving a decades-long scientific debate. 科学家们利用对来自人类、宠物和牲畜的100个样本的遗传分析,发现虽然实验室研究侧重于非性紧张,但人类的性形式更为常见,并有可能有助于遗传多样性、适应性和动物流行病的传播。 Using genetic analysis of 100 samples from humans, pets, and livestock, scientists found that while lab studies focused on an asexual strain, the more common sexual form exists in humans and likely aids genetic diversity, adaptation, and zoonotic spread. 这一发现有助于解释大约20%病例的抗药性,并可以改进预防和治疗战略。 This discovery helps explain drug resistance in about 20% of cases and could improve prevention and treatment strategies.
