在4月初之前,人人都怀疑一种新发现的冠状病毒是引起严重急性呼吸道综合症(SARS)的病因。为了加以证实,研究人员必须用这种病毒去感染动物,以此观察动物是否会得病,或得病后在体内是否会产生SARS病毒。换句话说,他们必须满足柯赫氏定律。 这一动物实验最终由荷兰鹿特丹伊斯默斯大学医学中心的病毒学家艾伯特·奥斯特豪斯(Albert Osterh-aus)等人完成。他们在严格的生物安全条件下用冠状病毒感染猴子,然后解剖猴子以便仔细研究它们的
Before early April, everyone suspected that a newly discovered coronavirus was the cause of severe acute respiratory syndrome (SARS). To confirm this, researchers must use the virus to infect animals in order to see if the animals get sick, or whether the SARS virus will be produced in the body after getting sick. In other words, they must satisfy Koch’s law. This animal experiment was eventually completed by Albert Osterh-aus et al., A virologist at the Ismas University Medical Center in Rotterdam, the Netherlands. They infected the monkeys with the coronavirus under strict biosafety conditions and then dissected the monkeys to study them carefully
