Cats may be spreading brain cancer to their owners, scientists warned last night.They have linked a parasite that breeds in cats’ stomachs with brain tumours in people. While they can’t prove that our feline friends are to blame, they say that properly researching the link could spare some people from developing the deadly disease. 科学家警告“养猫咪”这种习惯有可能增加主人患上癌症的可能,他们将脑部肿瘤与寄生在猫肠胃中的寄生虫联系起来,发现两者竟然有着不为人知的关系。
Brain cancer, in its various guises, claims more than 3,500 lives a year in the UK alone, and its causes are largely unknown. The parasite in the frame – Toxoplasma gondii – is carried by around a third of the world’s population deep inside their brains and has been linked to personality changes, in people as well as animals.
脑癌,有很多种表现形式,单单在英国被查出确切患上脑癌的患者每年就3500人,而因脑部肿瘤引发的案例更是无从计算。专家分析,有一种名为“弓形虫”与脑部肿瘤的发展有关系。弓形虫病又称弓浆虫病或毒浆原虫病,是一种世界性分布的人兽共患寄生性原虫病,病原为龚地弓形虫(Toxoplasma gondii),是一种细胞内的专性寄生原虫,在家畜和野生动物中广泛存在,感染率高,危害严重。此外,它还是由肉孢子虫科弓形虫属的龚地弓形虫引起的一种人畜共患的原虫病,其特点是虫体寄生于中间宿主体内所有的有核细胞内。
